	Okay, with that all in mind here are the snags:  The finer locking
	means that you can have one processor trying to send data
	out through an ethernet driver while another processor tries to
	access the same driver/card to do something else (such as get the
	card statistics for <tt>cat /proc/net/dev</tt>). Oops - your card
	stats just got sent out over the wire, while you got data for
	your stats instead. Yes, the card got confused by being asked
	to do two (or more!) things at once, and chances are it crashed
	your machine in the process.

	The scary
	part here is that a driver not yet updated with locks for stable
	MP operation will probably appear to be working in a MP machine
	under light network load, but will crash the machine or at least
	exhibit strange behaviour when two (or more!) processors try to
	do more than one of these three tasks at the same time.

	The updated MP aware ethernet driver will (at a
	minimum) require a lock
	around the driver that limits access at the entry points
	from the kernel into the driver to `one at a time please'.
	With this in place, things will be serialized so that the
	underlying hardware should be treated just as if it was being
	used in a UP machine, and so it should be stable. The downside
	is that the one lock around the whole ethernet driver has
	the same negative performance implications that having one big
	lock around the whole kernel had (but on a smaller scale) - i.e.
	you can only have one processor dealing with the card
	at a time.
	[Technical Note: The performance impact may also include
	increased interrupt latencies if the locks that need to be
	added are of the <tt/irqsave/ type and they are held
	for a long time.&rsqb

	Possible improvements on this situation can be made in two
	ways. You can try to minimize the time between when the lock is
	taken and when it is released, and/or you can implement finer
	grained locking within the driver (e.g. a lock around the whole
	driver would be overkill if a lock or two protecting against
	simultaneous access to a couple of sensitive registers/settings
	on the card would suffice).

	However, for older non-intelligent
	cards that were never designed with MP use in mind, neither of
	these improvements may be feasible. Worse yet is that the
	non-intelligent cards typically require the processor to move
	the data between the card and the computer memory, so in a
	worst case scenario the lock will be held the whole time that
	it takes to move each 1.5kB data packet over an ISA bus.

	The more modern intelligent cards typically move network data
	directly to and from the computer memory without any help from
	a processor.  This is a big win, since the lock is then only
	held for the short time it takes the processor to tell the card
	where in memory to get/store the next network data packet. More
	modern card designs are less apt to require a single big
	lock around the whole driver as well.

	for the different HZ value that the Alpha uses.
	(i.e <tt/timeout=2;/ becomes <tt>timeout=2*HZ/100;</tt>)

	-replace any I/O memory (640k to 1MB) pointer dereferences with
	the appropriate readb() writeb() readl() writel() calls, as
	shown in this example.

<code>
-	int *mem_base = (int *)dev->mem_start;

	Details on handling memory accesses in an architecture

	For those not yet convinced, the 3c501 can only do one
	thing at a time -- while you are removing one packet
	from the single-packet buffer it cannot receive
	another packet, nor can it receive a packet while
	loading a transmit packet. This was fine for a
	network between two 8088-based computers where
	processing each packet and replying took 10's of
	msecs, but modern networks send back-to-back
	packets for almost every transaction.

	AutoIRQ works, DMA isn't used, the autoprobe only
	looks at <tt/0x280/ and <tt/0x300/, and the debug level is set
	with the third boot-time argument.

	Once again, the use of a 3c501 is <em/strongly discouraged/!
	Even more so with a IP multicast kernel, as you will
	grind to a halt while listening to <em/all/ multicast
	packets. See the comments at the top of the source code
	for more details.

<sect2>EtherLink II, 3c503, 3c503/16<label id="3c503">
<p>
	Status: Supported, Driver Name: 3c503 (+8390)

	The 3c503 does not have ``EEPROM setup'',
	so a diagnostic/setup program
	isn't needed before running the card with Linux. The
	shared memory address of the 3c503 is set using jumpers
	that are shared with the boot PROM address. This is
	confusing to people familiar with other ISA cards,
	where you always leave the jumper set to ``disable''
	unless you have a boot PROM.

	These cards should be about the same speed as the same bus
	width WD80x3, but turn out to be actually a bit slower.
	These shared-memory ethercards also have a
	programmed I/O mode that doesn't use the 8390
	facilities (their engineers found too many bugs!)
	The Linux 3c503 driver can also work with the 3c503
	in programmed-I/O mode, but this is slower and less
	reliable than shared memory mode. Also, programmed-I/O
	mode is not as well tested when updating the drivers.
	You shouldn't use the programmed-I/O mode
	unless you need it for MS-DOS compatibility.

	The 3c503's IRQ line is set in software, with no hints
	from an EEPROM. Unlike the MS-DOS drivers, the
	Linux driver has capability to autoIRQ: it uses the
	first available IRQ line in {5,2/9,3,4}, selected each
	time the card is ifconfig'ed. (Older driver versions
	selected the IRQ at boot time.) The ioctl() call
	in `ifconfig' will return EAGAIN if no IRQ line is
	available at that time.

	Some common problems that people have with the 503
	are discussed in <ref id="3com-probs" name="Problems with...">.

	If you intend on using this driver as a loadable module
	you should probably see
	<ref id="modules" name="Using the Ethernet Drivers as Modules">
	for module specific information.

	Note that some old diskless 386 workstations have an on board
	3c503 (made by 3Com and sold under different names, like `Bull')
	but the vendor ID is not a 3Com ID and so it won't be detected.
	More details can be found in the Etherboot package, which you
	will need anyways to boot these diskless boxes.

<sect2>Etherlink Plus 3c505<label id="3c505">

	This is a driver that was written by Craig Southeren
	<tt/geoffw@extro.ucc.su.oz.au/. These cards also
	use the i82586 chip.
	There are not that many of these cards about.
	It is included in the standard kernel, but it is classed as

<sect2>Etherlink-16 3c507<label id="3c507">
<p>
	Status: Semi-Supported, Driver Name: 3c507

	This card uses one of the Intel chips, and the
	development of the driver is closely related to
	the development of the Intel Ether Express driver.
	The driver is included in the standard kernel
	release, but as an alpha driver.
	See <ref id="alfa" name="Alpha Drivers"> for important
	information on using alpha-test ethernet drivers
	with Linux. 

<sect2>Etherlink III, 3c509 / 3c509B<label id="3c509">
<p>
	Status: Supported, Driver Name: 3c509

	This card is fairly inexpensive and has
	good performance for an ISA non-bus-master design.
	The drawbacks are that the original 3c509
	requires very low interrupt latency. The 3c509B
	shouldn't suffer from the same problem, due to
	having a larger buffer. (See below.) These cards
	use PIO transfers, similar to a ne2000 card, and so
	a shared memory card such as a wd8013 will be more
	efficient in comparison.

	The original 3c509 has a small packet buffer
	(4kB total, 2kB Rx, 2kB Tx), causing the driver to
	occasionally drop a packet if interrupts are masked for
	too long. To minimize this problem, you can try unmasking
	interrupts during IDE disk transfers (see <tt/man hdparm/) and/or
	increasing your ISA bus speed so IDE transfers finish sooner.

	The newer model 3c509B has 8kB on board, and the buffer
	can be split 4/4, 5/3 or 6/2 for Rx/Tx. This setting
	is changed with the DOS configuration utility, and is stored
	on the EEPROM. This should alleviate the
	above problem with the original 3c509.

	3c509B users should use either the supplied DOS
	utility to disable the <em/plug and play/ support, <em/and/
	to set the output media to what they require. The linux
	driver currently does <em/not/ support the Autodetect
	media setting, so you <em/have/ to select 10Base-T or
	10Base-2 or AUI.
	Note that to turn off PnP entirely, you should do a
	<tt>3C5X9CFG /PNP:DISABLE</tt> and then follow that with a hard
	reset to ensure that it takes effect.

	Some people ask about the ``Server or Workstation'' and ``Highest
	Modem Speed'' settings presented in the DOS configuration utility.
	Donald writes ``These are only hints to the drivers, and the Linux
	driver does not use these parameters: it always optimizes for high
	throughput rather than low latency (`Server'). Low latency was
	critically important for old, non-windowed, IPX throughput.
	To reduce the latency the MS-DOS driver for the 3c509 disables
	interrupts for some operations, blocking serial port interrupts.
	Thus the need for the `modem speed' setting.  The Linux driver avoids
	the need to disable interrupts for long periods by operating only
	on whole packets e.g. by not starting to transmit a packet
	until it is completely transferred to the card.''

	Note that the ISA card detection uses a different method
	than most cards. Basically, you ask the cards to respond
	by sending data to an ID_PORT (port <tt/0x100/ to <tt/0x1ff/
	on intervals of <tt/0x10/).
	This detection method means that
	a particular card will <em/always/ get detected first
	in a multiple ISA 3c509 configuration.
	The card with the lowest hardware ethernet address
	will <em/always/ end up being <tt/eth0/. This shouldn't matter
	to anyone, except for those people who want to assign
	a 6 byte hardware address to a particular interface.
	If you have multiple 3c509 cards, it is best to append
	<tt/ether=0,0,ethN/ commands without the I/O port specified
	(i.e. use I/O=zero) and allow the probe to sort out which
	card is first. Using a non-zero I/O value will ensure that it
	does not detect all your cards, so don't do it.

	If this really bothers you, have a look at Donald's latest driver,
	as you may be able to use a <tt/0x3c509/ value in the unused mem
	address fields to order the detection to suit your needs.

<sect2>3c562
<p>
	Status: Supported, Driver Name: 3c589 (distributed separately)

	This PCMCIA card is the combination of a 3c589B ethernet card
	with a modem. The modem appears as a standard modem to the
	end user. The only difficulty is getting the two separate
	linux drivers to share one interrupt. There are a couple of new
	registers and some hardware interrupt sharing support.
	You need to use a v2.0 or newer kernel that has the support
	for interrupt sharing.

<!--

XXX Product discontinued so this can go soon...

	As a side note, the modem part of the card has been reported
	to be not well documented for the end user (the manual just
	says `supports the AT command set') and it may not connect
	as well as other name brand modems. The recommendation is to
	buy a 3c589B instead, and then get a PCMCIA modem card from
	a company that specializes in modems.

	Note that to access this driver during <tt/make config/
	you still have to answer `Y' when asked ``Prompt for

	the first. This is simply due to lack of feedback on the
	driver stability due to it being a relatively rare card.
	If you have problems with the driver that ships with
	the kernel then you may be interested in the alternative 
	driver available at:
	<tt>http://www.cc.hit-u.ac.jp/nagoya/at1700/</tt>

	The Allied Telesis AT1700 series ethercards are based
	on the Fujitsu MB86965. This chip uses a programmed
	I/O interface, and a pair of fixed-size transmit
	buffers. This allows small groups of packets to
	be sent back-to-back, with a short pause while
	switching buffers.
	
	A unique feature is the ability to drive 150ohm STP
	(Shielded Twisted Pair) cable commonly installed for
	Token Ring, in addition to 10baseT 100ohm UTP
	(unshielded twisted pair). A fibre optic
	version of the card (AT1700FT) exists as well.
	
	The Fujitsu chip used on the AT1700 has a design flaw:
	it can only be fully reset by doing a power cycle of the machine.
	Pressing the reset button doesn't reset the bus interface. This
	wouldn't be so bad, except that it can only be reliably detected
	when it has been freshly reset. The solution/work-around is to
	power-cycle the machine if the kernel has a problem detecting
	the AT1700.

	detailed description of all the relevant AMD ethernet
	products which helped clear up this section.

<sect2>AMD LANCE (7990, 79C960/961/961A, PCnet-ISA)<label id="lance">
<p>
	Status: Supported, Driver Name: lance

	There really is no AMD ethernet card. You are probably reading this
	because the only markings you could find on your card said AMD
	and the above number. The 7990 is the original `LANCE' chip,
	but most stuff (including this document) refer to all these
	similar chips as `LANCE' chips. (...incorrectly, I might add.)

	These above numbers refer to chips from AMD
	that are the heart of many ethernet cards.
	For example, the Allied Telesis AT1500 (see
	<ref id="at-1500" name="AT1500">) and the NE1500/2100 (see
	<ref id="ne1500" name="NE1500">)  use these chips.

	The 7990/79c90 have long been replaced by newer versions.
	The 79C960 (a.k.a. PCnet-ISA) essentially contains the 79c90
	core, along with all the other hardware support required, which
	allows a single-chip ethernet solution. The 79c961 (PCnet-ISA+)
	is a jumperless Plug and Play version of the '960. The final
	chip in the ISA series is the 79c961A (PCnet-ISA II), which
	adds full duplex capabilities.
	All cards with one of these chips should work with
	the lance.c driver, with the exception of very old cards that
	used the original 7990 in a shared memory configuration. These
	old cards can be spotted by the lack of jumpers for a DMA channel.

	One common problem people have is the `busmaster arbitration
	failure' message. This is printed out when the LANCE driver
	can't get access to the bus after a reasonable amount of time
	has elapsed (50us). This usually indicates that the motherboard
	implementation of bus-mastering DMA is broken, or some other device
	is hogging the bus, or there is a DMA channel conflict. If your BIOS
	setup has the `GAT option' (for Guaranteed Access Time) then try
	toggling/altering that setting to see if it helps.

	Also note that the driver only looks at the addresses:
	<tt/0x300, 0x320, 0x340, 0x360/ for a valid card, and any
	address supplied by an <tt/ether=/ boot argument is silently
	ignored (this will be fixed) so make sure your card is configured
	for one of the above I/O addresses for now.
	
	The driver will still work fine, even
	if more than 16MB of memory is installed, since low-memory
	`bounce-buffers' are used when needed (i.e. any data from
	above 16MB is copied into a buffer below 16MB before being
	given to the card to transmit.)

	The DMA channel can be set with the low bits
	of the otherwise-unused dev->mem_start value (a.k.a. PARAM_1).
	(see <ref id="ether" name="PARAM_1">)
	If unset it is probed for by enabling each free DMA channel
	in turn and checking if initialization succeeds.

	The HP-J2405A board is an exception: with this board it's easy
	to read the EEPROM-set values for the IRQ, and DMA.

	See <ref id="amd-notes" name="Notes on AMD...">
	for more info on these chips.

<sect2>AMD 79C965 (PCnet-32)<label id="pcnet-32">
<p>
	Status: Supported, Driver Name: pcnet32

	This is the PCnet-32 -- a 32 bit bus-master version of the
	original LANCE chip for VL-bus and local bus systems.
	chip.  While these chips can be operated with the standard
	<tt/lance.c/ driver, a 32 bit version (<tt/pcnet32.c/) is
	also available that does not have to concern itself with
	any 16MB limitations associated with the ISA bus.
	
<sect2>AMD 79C970/970A (PCnet-PCI)<label id="pcnet-pci">
<p>
	Status: Supported, Driver Name: pcnet32

	This is the PCnet-PCI -- similar to the PCnet-32, but designed
	for PCI bus based systems. Please see the
	above PCnet-32 information.
	This means that you need to build a kernel with
	PCI BIOS support enabled. The '970A adds full duplex support
	along with some other features to the original '970 design.

	Note that the Boca implementation of the 79C970 fails on
	fast Pentium machines. This is a hardware problem, as it
	affects DOS users as well. See the Boca section for more
	details.

<sect2>AMD 79C971 (PCnet-FAST)
<p>
	Status: Supported, Driver Name: pcnet32

	This is AMD's 100Mbit chip for PCI systems, which also supports
	full duplex operation. It was introduced in June 1996.

<sect2>AMD 79C972 (PCnet-FAST+)
<p>
	Status: Unknown, Driver Name: pcnet32

	This should also work just like the '971 but this has yet to
	be confirmed.

<sect2>AMD 79C974 (PCnet-SCSI)
<p>
	Status: Supported, Driver Name: pcnet32

	This is the PCnet-SCSI --  which is basically treated like
	a '970 from an Ethernet point of view.
	Also see the above information. Don't ask if the
	SCSI half of the chip is supported -- this is the
	<em/Ethernet-HowTo/, not the SCSI-HowTo.

<sect1>Ansel Communications<label id="ansel">
<p>

<sect2>AC3200 EISA
<p>
	Status: Semi-Supported, Driver Name: ac3200

	Note that to access this driver during <tt/make config/
	you still have to answer `Y' when asked ``Prompt for
	development and/or incomplete code/drivers?'' at
	the first. This is simply due to lack of feedback on the
	driver stability due to it being a relatively rare card.

	This driver is included in the present kernel as an
	alpha test driver. It is based on the common NS8390
	chip used in the ne2000 and wd80x3 cards.
	Please see <ref id="alfa" name="Alpha Drivers"> in
	this document for important information regarding
	alpha drivers.

	If you use it, let one of us know how things work out,
	as feedback has been low, even though the driver has
	been in the kernel since v1.1.25.

	If you intend on using this driver as a loadable module
	you should probably see
	<ref id="modules" name="Using the Ethernet Drivers as Modules">
	for module specific information.

<sect1>Apricot
<p>

<sect2>Apricot Xen-II On Board Ethernet
<p>
	Status: Semi-Supported, Driver Name: apricot

	This on board ethernet uses an i82596 bus-master chip.
	It can only be at I/O address <tt/0x300/.
	By looking at the driver source,
	it appears that the IRQ is also hardwired to 10.

	Earlier versions of the driver had a tendency to think
	that anything living at <tt/0x300/ was an apricot NIC.
	Since then the hardware address is checked to avoid these
	false detections.

<sect1>Arcnet<label id="arcnet">
<p>
	Status: Supported, Driver Name: arcnet (arc-rimi, com90xx, com20020)

	With the very low cost and better performance of ethernet,
	chances are that most places will be giving away their Arcnet
	hardware for free, resulting in a lot of home systems with Arcnet.

	An advantage of Arcnet is that all of the cards have identical
	interfaces, so one driver will work for everyone. It also has
	built in error handling so that it supposedly never loses a packet.
	(Great for UDP traffic!)

	Avery Pennarun's arcnet driver has been in the
	default kernel sources since 1.1.80. The arcnet driver
	uses `arc0' as its name instead of the usual `eth0' for
	ethernet devices.
	Bug reports and success stories can be mailed to:

	<tt>apenwarr@foxnet.net</tt>

	There are information files contained in the standard kernel for
	setting jumpers and general hints.

	Supposedly the driver also works with the 100Mbs ARCnet cards
	as well!

<sect1>AT&T
<p>

	Note that AT&T's StarLAN is an orphaned technology, like
	SynOptics LattisNet, and can't be used in a standard 10Base-T
	environment, without a hub that `speaks' both.

<sect2>AT&T T7231 (LanPACER+)
<p>
	Status: Not Supported.

	These StarLAN cards use an interface similar to the i82586
	chip. At one point, Matthijs Melchior
	(<tt/matthijs.n.melchior@att.com/) was playing with the 3c507
	driver, and almost had something useable working. Haven't
	heard much since that.

<sect1>Boca Research<label id="boca">
<p>

	Yes, they make more than just multi-port serial cards.  :-)

<sect2>Boca BEN (ISA, VLB, PCI)<label id="boca-ben">
<p>
	Status: Supported, Driver Name: lance, pcnet32

	These cards are based on AMD's PCnet chips.
	Perspective buyers should be warned that many users have had
	endless problems with these VLB/PCI cards. Owners of fast Pentium
	systems have been especially hit. Note that this is not a driver
	problem, as it hits DOS/Win/NT users as well.
	Boca's technical support number is (407) 241-8088, and you
	can also reach them at <tt/75300.2672@compuserve.com/.
	The older ISA cards don't appear to suffer the same problems.

	Donald did a comparitive test with a Boca PCI card and
	a similar Allied Telsyn PCnet/PCI implementation, which showed
	that the problem lies in Boca's implementation of the PCnet/PCI
	chip. These test results can be accessed on Don's www server.

	<url url="http://cesdis.gsfc.nasa.gov/linux/" name="Linux at CESDIS">

	Boca is offering a `warranty repair' for
	affected owners, which involves adding one of the missing
	capacitors, but it appears that this fix doesn't work 100
	percent for most people, although it helps some.

	If you are <em/still/ thinking of buying one of these cards, then
	at least try and get a 7 day unconditional return policy,
	so that if it doesn't work properly in your system, you
	can return it.

	Donald writes:
	`Yes, another one of these companies that won't release its
	programming information. They waited for months before actually
	confirming that all their information was proprietary, deliberately
	wasting my time. Avoid their cards like the plague if you can.
	Also note that some people have phoned Cabletron, and have been
	told things like `a D. Becker is working on a driver
	for linux' -- making it sound like I work for them. This is
	NOT the case.'

<!--
	If you feel like asking them why they don't want to release their
	low level programming info so that people can use their cards, write
	to support@ctron.com.
	Tell them that you are using Linux, and are disappointed that they
	don't support open systems. And no, the usual driver development
	kit they supply is useless. It is just a DOS object file that
	you are supposed to link against. Which you aren't allowed to

	Apparently Cabletron has changed their policy with respect to
	programming information (like Xircom) since Donald made the above
	comment several years ago -- send e-mail to <tt/support@ctron.com/
	if you want to verify this or ask for programming information.
	However, at this point in time, there is little demand for
	modified/updated drivers for the older E20xx and E21xx cards.
	

<sect2>E10**, E10**-x, E20**, E20**-x<label id="e10xx">
<p>
	Status: Semi-Supported, Driver Name: ne (+8390)

	These are NEx000 almost-clones that are reported to
	work with the standard NEx000 drivers, thanks to a
	ctron-specific check during the probe. If there are
	any problems, they are unlikely to be fixed, as the
	programming information is unavailable.

<sect2>E2100<label id="e2100">
<p>
	Status: Semi-Supported, Driver Name: e2100 (+8390)

	Again, there is not much one can do when the
	programming information is proprietary.
	The E2100 is a poor design. Whenever it maps its
	shared memory in during a packet transfer, it
	maps it into the <em/whole 128K region!/ That means you
	<bf/can't/ safely use another interrupt-driven shared
	memory device in that region, including another E2100.
	It will work most of the time, but every once in
	a while it will bite you. (Yes, this problem can
	be avoided by turning off interrupts while
	transferring packets, but that will almost certainly
	lose clock ticks.) Also, if you mis-program the board,
	or halt the machine at just the wrong moment, even
	the reset button won't bring it back. You will <em/have/
	to turn it off and <em/leave/ it off for about 30 seconds.

	Media selection is automatic, but you can override this
	with the low bits of the dev->mem_end parameter.
	See <ref id="ether" name="PARAM_2">. Module users
	can specify an <tt/xcvr=N/ value as an <tt/option/ in
	the <tt>/etc/conf.modules</tt> file.

	Also, don't confuse the E2100 for a NE2100 clone.
	The E2100 is a shared memory NatSemi DP8390 design,
	roughly similar to a brain-damaged WD8013, whereas
	the NE2100 (and NE1500) use a bus-mastering AMD
	LANCE design.

	There is an E2100 driver included in the standard kernel.
	However, seeing as programming info isn't available,
	don't expect bug-fixes. Don't use one
	unless you are already stuck with the card.

	If you intend on using this driver as a loadable module
	you should probably see
	<ref id="modules" name="Using the Ethernet Drivers as Modules">
	for module specific information.

<sect2>E22**<label id="e2200">

<sect2>Compaq Deskpro / Compaq XL (Embedded AMD Chip)
<p>
	Status: Supported, Driver Name: pcnet32

	Machines such as the XL series have an AMD 79c97x PCI chip
	on the mainboard that can be used with the standard LANCE
	driver. But before you can use it, you have to do some
	trickery to get the PCI BIOS to a place where Linux can
	see it. Frank Maas was kind enough to provide the
	details:

	`` The problem with this Compaq machine however is that the PCI
	directory is loaded in high memory, at a spot where the Linux
	kernel can't (won't) reach. Result: the card is never detected nor
	is it usable (sideline: the mouse won't work either)
	The workaround (as described thoroughly in
	http://www-c724.uibk.ac.at/XL/)
	is to load MS-DOS, launch a little driver Compaq wrote and then
	load the Linux kernel using LOADLIN. Ok, I'll give you time to
	say `yuck, yuck', but for now this is the only working solution
	I know of. The little driver simply moves the PCI directory to
	a place where it is normally stored (and where Linux can find it).''

	These cards use a proprietary

	earlier cards like the DE200. These cards support both shared
	memory or programmed I/O, although you take about a 50&percnt
	performance hit if you use PIO mode. The shared memory size can
	be set to 2kB, 32kB or 64kB, but only 2 and 32 have been tested
	with this driver. David says that the performance is virtually
	identical between the 2kB and 32kB mode. There is more information
	(including using the driver as a loadable module) at the top
	of the driver file <tt/ewrk3.c/ and also in <tt/README.ewrk3/.
	Both of these files come with the standard kernel distribution.
	This driver has Alpha CPU support like depca.c does.

	The standard driver has a number
	of interesting ioctl() calls that can be used to get or clear
	packet statistics, read/write the EEPROM, change the
	hardware address, and the like. Hackers can see the source
	code for more info on that one.

<sect2>DEC 21040, 21041, 2114x, Tulip <label id="dec-21040">
<p>
	Status: Supported, Driver Name: de4x5, tulip

	The DEC 21040 is a bus-mastering single chip ethernet solution
	from Digital, similar to AMD's PCnet chip. The 21040 is
	specifically designed for the PCI bus architecture.
	SMC's new EtherPower PCI card uses this chip.

	You have a choice of <em/two/ drivers for cards based on this
	chip. There is the DE425 driver discussed above, and the
	generic 21040  `tulip' driver.

	<bf/Warning:/ Even though your card may be based upon this chip,
	<em/the drivers may not work for you/. David C. Davies writes:

	``There are no guarantees that either `tulip.c' OR `de4x5.c'
	will run any DC2114x based card other than those they've been
	written to support.  WHY?? You ask.  Because there is a register,
	the General Purpose Register (CSR12) that (1) in the DC21140A is
	programmable by each vendor and they all do it differently
	(2) in the DC21142/3 this is now an SIA control register
	(a la DC21041). The only small ray of hope is that we can decode the
	SROM to help set up the driver. However, this is not a guaranteed
	solution since some vendors (e.g. SMC 9332 card) don't follow the
	Digital Semiconductor recommended SROM programming format."

	In non-technical terms, this means that if you aren't sure that an
	unknown card with a DC2114x chip will work with the linux driver(s),
	then make sure you can return the card to the place of
	purchase <em/before/ you pay for it.

	The updated 21041 chip is also found in place of the 21040
	on most of the later SMC EtherPower cards.
	The 21140 is for supporting 100Base-? and
	works with the Linux drivers for the 21040 chip.
	To use David's <tt/de4x5/ driver with non-DEC cards, have a
	look at <tt/README.de4x5/ for details.

	Donald has used SMC EtherPower-10/100 cards to develop
	the `tulip' driver. Note that the driver that is
	in the standard kernel tree at the moment is not the most
	up to date version. If you are having trouble with this driver,
	you should get the newest version from Donald's ftp/WWW
	site.

	<url url="http://cesdis.gsfc.nasa.gov/linux/drivers/tulip.html"
		name="Tulip Driver">

	The above URL also contains a (non-exhaustive) list of
	various cards/vendors that use the 21040 chip.

	Also note that the tulip driver is still considered an <em/alpha/
	driver (see <ref id="alfa" name="Alpha Drivers">) at the
	moment, and should be treated as such. To use it, you
	will have to edit <tt>arch/i386/config.in</tt> and
	uncomment the line for <tt/CONFIG_DEC_ELCP/ support.

	Donald has even set up a mailing list for tulip driver

	The driver in the v2.0 kernel seems to work much better
	for those who have tried it, although the driver source still
	lists it as experimental and more problematic on faster
	machines.

	The comments at the top of the
	driver source list some of the problems (and fixes!) associated

<sect1>Novell Ethernet, NExxxx and associated clones.<label id="novell">

<sect2>NE1000, NE2000<label id="ne2k">
<p>
	Status: Supported, Driver Name: ne (+8390)

	The ne2000 is now a generic name for a bare-bones design around
	the NatSemi 8390 chip. They use programmed I/O rather than
	shared memory, leading to easier installation but
	slightly lower performance and a few problems. 
	Some of the more common problems that arise
	with NE2000 cards are listed in 
	<ref id="ne2k-probs" name="Problems with...">

	Some NE2000 clones use the National
	Semiconductor `AT/LANTic' 83905 chip, which offers
	a shared memory mode similar to the wd8013 and EEPROM
	software configuration. The shared memory mode will offer
	less CPU usage (i.e. more efficient) than the programmed
	I/O mode.

	In general it is not a good idea to put a NE2000
	clone at I/O address <tt/0x300/ because nearly
	<em/every/ device driver probes there at boot. Some
	poor NE2000 clones don't take kindly to being prodded
	in the wrong areas, and will respond by locking your
	machine. Also <tt/0x320/ is bad because SCSI drivers
	probe into <tt/0x330/.

	Donald has written a NE2000 diagnostic program (ne2k.c)
	for all ne2000 cards.

<sect2>NE2000-PCI (RealTek/Winbond/Compex)<label id="ne2k-pci">
<p>
	Status: Supported, Driver Name: ne, ne2k-pci (+8390)

	Yes, believe it or not, people are making PCI cards based on
	the more than ten year old interface 
	design of the ne2000. At the moment
	nearly all of these cards are based on the RealTek 8029 chip,
	or the Winbond 89c940 chip. The Compex, KTI, VIA and Netvin cards
	apparently also use these chips, but have a different PCI ID.

	The latest v2.0 kernel has support to automatically detect all
	these cards and use them. (If you are using a kernel v2.0.34 or
	older, you should upgrade to ensure your card will be detected.)
	There are now two drivers to choose from; the original ISA/PCI
	<tt/ne.c/ driver, and a relatively new PCI-only <tt/ne2k-pci.c/
	driver.

	To use the original ISA/PCI driver you have to say `Y'  to
	the `Other ISA cards' option when running <tt/make config/ as
	you are actually using the same NE2000 driver as the ISA cards
	use. (That should also give you a hint that these cards aren't
	anywhere as intelligent as say a PCNet-PCI or DEC 21040 card...)

	The newer PCI-only driver differs from the ISA/PCI driver in
	that all the support for old NE1000 8 bit cards has been removed
	and that data is moved to/from the card in bigger blocks, without
	any intervening pauses that the older ISA-NE2000's required for
	reliable operation.  The result is a driver that is slightly
	smaller and slightly more efficient, but don't get too excited
	as the difference will not be obvious under normal use.  (If you
	really wanted maximum efficiency/low CPU use, then a PCI-NE2000
	is simply a very poor choice.) Driver updates and more
	information can be found at:

	<tt>http://cesdis.gsfc.nasa.gov/linux/drivers/ne2k-pci.html</tt>

	If you have a NE2000 PCI card that is <em/not/  detected by
	the most current version of the driver, please contact the
	maintainer of the NE2000 driver as listed
	in <tt>/usr/src/linux/MAINTAINERS</tt> along with the output
	from a <tt>cat /proc/pci</tt> and <tt>dmesg</tt> so that
	support for your card can also be added to the driver.

	Also note that various card makers have been known to put
	`NE2000 Compatible' stickers on their product boxes even when
	it is completely different (e.g. PCNet-PCI or RealTek 8139).

<sect2>ES3210
<p>
	Status: Semi-Supported, Driver Name: es3210

	This is an EISA 8390 based shared memory card. An experimetal
	driver is shipped with v2.2 kernels and it is reported to
	work fine, but the EISA IRQ and shared memory address detection
	appears not to work with (at least) the early revision cards.
	(This problem is not unique to the Linux world either...)
	In that case, you have to supply them to the driver.
	For example, card at IRQ 5 and shared memory <tt/0xd0000/,
	with a modular driver, add
	<tt/options es3210 irq=5 mem=0xd0000/ to <tt>/etc/conf.modules</tt>.
	Or with the driver compiled into the kernel, supply at
	boot <tt/ether=5,0,0xd0000,eth0/
	The I/O base is automatically detected
	and hence a value of zero should be used.

<sect2>NI5010
<p>
	Status: Semi-Supported, Driver Name: ni5010 

	You used to have to go get the driver for these old 8 bit 
	MiCom-Interlan cards separately, but now it is shipped with
	the v2.2 kernels as an experimental driver.
	
<sect2>NI5210
<p>
	Status: Semi-Supported, Driver Name: ni52

	This card also uses one of the Intel chips. 
	Michael Hipp has written a driver for this card. It is included
	in the standard kernel as an `alpha' driver. Michael would like
	to hear feedback from users that have this card. See
	<ref id="alfa" name="Alpha Drivers"> for important

<sect2>NI6510 (not EB)<label id="ni65xx">
<p>
	Status: Semi-Supported, Driver Name: ni65

	There is also a driver for the LANCE based NI6510, and it
	is also written by Michael Hipp. Again, it is also an
	`alpha' driver. For some reason, this card is not compatible
	with the generic LANCE driver. See
	<ref id="alfa" name="Alpha Drivers"> for important
	information on using alpha-test ethernet drivers
	with Linux.

<sect2>EtherBlaster (aka NI6510EB)
<p>
	Status: Supported, Driver Name: lance

	As of kernel 1.3.23, the generic LANCE driver had a check
	added to it for the <tt/0x52, 0x44/ NI6510EB specific signature.
	Others have reported that this signature is not the same
	for all NI6510EB cards however, which will cause the lance
	driver to not detect your card. If this happens to you, you
	can change the probe (at about line 322 in lance.c) to printk()
	out what the values are for your card and then use them instead
	of the <tt/0x52, 0x44/ defaults.

	The cards should probably be run in `high-performance' mode
	and not in the NI6510 compatible mode when using the lance driver.

	The ethernet part of Western Digital was bought out by SMC
	many years ago when the wd8003 and wd8013 were the main

	PCI products to their range.

<sect2>WD8003, SMC Elite
<p>
	Status: Supported, Driver Name: wd (+8390)

	These are the 8-bit versions of the card. The
	8 bit 8003 is slightly less expensive, but only
	worth the savings for light use. Note that some
	of the non-EEPROM cards (clones with jumpers, or
	old <em/old/ old wd8003 cards) have no way of reporting
	the IRQ line used. In this case, auto-irq is used, and if
	that fails, the driver silently assings IRQ 5.
	You can get the SMC setup/driver disks from SMC's ftp site.
	Note that some of the
	newer SMC `SuperDisk' programs will fail to detect
	the real old EEPROM-less cards. The file <tt/SMCDSK46.EXE/
	seems to be a good all-round choice. Also the jumper
	settings for all their cards are in an ASCII text file in the
	aforementioned archive. The latest (greatest?) version
	can be obtained from <tt/ftp.smc.com/.

	As these are basically the
	same as their 16 bit counterparts (WD8013 / SMC Elite16),
	you should see the next section for more information.


<sect2>WD8013, SMC Elite16<label id="8013">
<p>
	Status: Supported, Driver Name: wd (+8390)

	Over the
	years the design has added more registers and an
	EEPROM. (The first wd8003 cards appeared about ten years ago!)
	Clones usually go by the `8013' name, and
	usually use a non-EEPROM (jumpered) design.
	Late model SMC cards will have the SMC 83c690 chip instead
	of the original Nat Semi DP8390 found on earlier cards.
	The shared memory design makes the cards a bit faster
	than PIO cards, especially with larger packets.
	More importantly, from the
	driver's point of view, it avoids a few bugs in the
	programmed-I/O mode of the 8390, allows safe
	multi-threaded access to the packet buffer, and
	it doesn't have a programmed-I/O data register that
	hangs your machine during warm-boot probes.

	Non-EEPROM cards that can't just read the selected
	IRQ will attempt auto-irq, and if that fails, they will
	silently assign IRQ 10. (8 bit versions will assign IRQ 5)

	Cards with a non standard amount of memory on board can
	have the memory size specified at boot (or as an option
	in <tt>/etc/conf.modules</tt> if using modules).
	The standard memory size is
	8kB for an 8bit card and 16kB for a 16bit card.
	For example, the older WD8003EBT cards could be jumpered
	for 32kB memory. To make full use of that RAM, you would
	use something like (for I/O=0x280 and IRQ 9):
<code>
	LILO: linux ether=9,0x280,0xd0000,0xd8000,eth0
</code>

	Also see <ref id="8013-probs" name="8013 problems">
	for some of the more common problems and frequently
	asked questions that pop up often.

	If you intend on using this driver as a loadable module
	you should probably see
	<ref id="modules" name="Using the Ethernet Drivers as Modules">
	for module specific information.

<sect2>SMC Elite Ultra<label id="ultra">
<p>
	Status: Supported, Driver Name: smc-ultra (+8390)

	This ethercard is based on the
	83c790 chip from SMC, which has
	a few new features over the 83c690. While it has a mode that is
	similar to the older SMC ethercards, it's not entirely
	compatible with the old WD80*3 drivers. However, in
	this mode it shares most of its code with the other
	8390 drivers, while operating slightly faster than a
	WD8013 clone.

	Since part of the Ultra <em/looks like/
	an 8013, the Ultra probe is supposed to find an
	Ultra before the wd8013 probe has a chance to
	mistakenly identify it.

	Donald mentioned that it is possible to write a separate
	driver for the Ultra's `Altego' mode which allows
	chaining transmits at the cost of inefficient use of receive
	buffers, but that will probably not happen.

	Bus-Master SCSI host adaptor users take note: In the
	manual that ships with Interactive UNIX, it mentions
	that a bug in the SMC Ultra will cause data corruption
	with SCSI disks being run from an aha-154X host adaptor.
	This will probably bite aha-154X compatible cards, such
	as the BusLogic boards, and the AMI-FastDisk SCSI host
	adaptors as well.

	SMC has acknowledged the problem occurs with
	Interactive, and older Windows NT drivers. It is
	a hardware conflict with early revisions of the card
	that can be worked around in the driver design. The current
	Ultra driver protects against this by only enabling the
	shared memory during data transfers with the card. Make sure
	your kernel version is at least 1.1.84, or that the driver
	version reported at boot is at least <tt/smc-ultra.c:v1.12/
	otherwise you are vulnerable.

<sect2>SMC EtherEZ (8416)
<p>
	Status: Supported, Driver Name: smc-ultra (+8390)

	This card uses SMC's 83c795 chip and supports the Plug 'n Play
	specification. It also has an <em/SMC Ultra/ compatible mode,
	which allows it to be used with the Linux Ultra driver.
	For best results, use the SMC supplied program (avail. from
	their www/ftp site) to disable PnP and configure it for
	shared memory mode.  See the above information for notes on
	the Ultra driver.

	For v1.2 kernels, the card had to be configured for
	shared memory operation. However v2.0 kernels can use the
	card in shared memory or programmed I/O mode. Shared
	memory mode will be slightly faster, and use
	less CPU resources as well.

<sect2>SMC EtherPower PCI (8432)<label id="smc-pci">

	Status: Supported, Driver Name: de4x5, tulip

	NB: The EtherPower II is an entirely different card. See
	below!
	These cards are
	a basic DEC 21040 implementation, i.e. one big chip
	and a couple of transceivers. Donald has used one
	of these cards for his development of the generic
	21040 driver (aka <tt/tulip.c/). Thanks to Duke Kamstra,
	once again, for supplying a card to do development on.

	Some of the later revisons of this card use the newer
	DEC 21041 chip, which may cause problems with
	older versions of the tulip driver. If you have problems,
	make sure you are using the latest driver release, which
	may not yet be included in the current kernel source tree.

<sect1>Identifying an Unknown Card<label id="mystery">
<p>

	Okay, so your uncle's cousin's neighbour's friend had a brother
	who found an old ISA ethernet card in the AT case he was using as
	a cage for his son's pet hampster. Somehow you ended up with
	the card and want to try and use it with linux, but nobody
	has a clue what the card is and there isn't any documentation.

	First of all, look for any obvious model numbers that might
	give a clue. Any model number that contains 2000 will most
	likely be a NE2000 clone. Any cards with 8003 or 8013
	on them somewhere will be Western/Digital WD80x3 cards
	or SMC Elite cards or clones of them.

<sect2>Identifying the Network Interface Controller
<p>
	Look for the biggest chip on the card. This will be the
	network controller (NIC) itself, and most can be identified by
	the part number. If you know which NIC is on the card, the
	following might be able to help you figure out what card it is.

	Probably still the most common NIC is the National Semiconductor
	DP8390 aka NS32490 aka DP83901 aka DP83902 aka DP83905 aka DP83907.
	And those are just the ones made by National! Other companies
	such as Winbond and UMC make DP8390 and DP83905 clone parts,
	such as the Winbond 89c904 (DP83905 clone) and the UMC 9090.
	If the card has some form of 8390 on it, then chances are it
	is a ne1000 or ne2000 clone card. The second most common 8390
	based card are wd80x3 cards and clones. Cards with a DP83905
	can be configured to be an ne2000 <em/or/ a wd8013. Never versions
	of the genuine wd80x3 and SMC Elite cards have an 83c690 in place
	of the original DP8390. The SMC Ultra cards have an 83c790,
	and use a slightly different driver than the wd80x3 cards.
	The SMC EtherEZ cards have an 83c795, and use the same driver
	as the SMC Ultra. All BNC cards based on some sort of 8390 or
	8390 clone will usually have an 8392 (or 83c692, or ???392)
	16 pin DIP chip very close to the BNC connector.

	Another common NIC found on older cards is the Intel i82586.
	Cards having this NIC include the 3c505, 3c507, 3c523, Intel
	EtherExpress-ISA, Microdyne Exos-205T, and the Racal-Interlan NI5210.
	
	The original AMD LANCE NIC was numbered AM7990, and newer
	revisions include the 79c960, 79c961, 79c965, 79c970, and 79c974.
	Most cards with one of the above will work with the Linux LANCE
	driver, with the exception of the old Racal-Interlan NI6510
	cards that have their own driver.

	Newer PCI cards having a DEC 21040, 21041, 21140, or similar
	number on the NIC should be able to use the linux tulip or
	de4x5 driver.

	Other PCI cards having a big chip marked RTL8029 or
	89C940 or 86C926 are ne2000
	clone cards, and the ne driver in linux version v2.0 and up
	should automatically detect these cards at boot.

<sect2>Identifying the Ethernet Address
<p>

	Each ethernet card has its own six byte address that is
	unique to that card. The first three bytes of that address
	are the same for each card made by that particular manufacturer.
	For example all SMC cards start with <tt/00:00:c0/.
	The last three are assigned by the manufacturer uniquely to each
	individual card as they are produced.

	If your card has a sticker on it giving all six bits of its
	address, you can look up the vendor from the first three.
	However it is more common to see only the last three bytes
	printed onto a sticker attached to a socketed PROM,
	which tells you nothing.

	You can determine which vendors have which assigned addresses
	from RFC-1340. Apparently there is a more up to date listing
	available in various places as well. Try a WWW or FTP search
	for <tt/EtherNet-codes/ or <tt/Ethernet-codes/ and you will
	find something.

<sect2>Tips on Trying to Use an Unknown Card
<p>

	If you are still not sure what the card is, but have at least
	narrowed it down some, then you can build a kernel with a
	whole bunch of drivers included, and see if any of them
	autodetect the card at boot.

	If the kernel doesn't detect the card, it may be that the
	card is not configured to one of the addresses that the
	driver probes when looking for a card. In this case, you
	might want to try getting <tt/scanport.tar.gz/ from your
	local linux ftp site, and see if that can locate where your
	card is jumpered for. It scans ISA I/O space from <tt/0x100/
	to <tt/0x3ff/ looking for devices that aren't registered in
	<tt>/proc/ioports</tt>. If it finds an unknown device starting
	at some particular address, you can then explicity point the
	ethernet probes at that address with an <tt/ether=/ boot
	argument.

	If you manage to get the card detected, you can then
	usually figure out the unknown jumpers by changing them
	one at a time and seeing at what I/O base and IRQ that the
	card is detected at. The IRQ settings can also usually be
	determined by
	following the traces on the back of the card to where the
	jumpers are soldered through. Counting the `gold fingers'
	on the backside, from the end of the card with the metal bracket,
	you have IRQ 9, 7, 6, 5, 4, 3, 10, 11, 12, 15, 14 at fingers
	4, 21, 22, 23, 24, 25, 34, 35, 36, 37, 38 respectively.
	Eight bit cards only have up to finger 31.

	Jumpers that appear to do nothing usually are for selecting
	the memory address of an optional boot ROM. Other jumpers that
	are located near the BNC or RJ-45 or AUI connectors are usually
	to select the output media. These are also typically near
	the `black box' voltage converters marked YCL, Valor, or Fil-Mag.

	A nice collection of jumper settings for various cards can
	be found at the following URL:

	<url url="http://www.slug.org.au/NIC/" name="Ethercard Settings">


<sect1>Drivers for Non-Ethernet Devices
<p>

	There are a few other drivers that are in the linux source
	that present an <em/ethernet-like/ device to network
	programs, while not really being ethernet. These are briefly
	listed here for completeness.

	<tt/dummy.c/ - The purpose of this driver is to provide a device
	to point a route through, but not to actually transmit packets.

	<tt/eql.c/ - Load Equalizer, enslaves multiple devices (usually
	modems) and balances the Tx load across them while presenting
	a single device to the network programs.

	<tt/ibmtr.c/ - IBM Token Ring, which is not really ethernet.
	Broken-Ring requires source routing and other uglies.

	<tt/loopback.c/ - Loopback device, for which all packets
	from your machine and destined for your own machine go.
	It essentially just moves the packet off the Tx queue and
	onto the Rx queue.

	<tt/pi2.c/ - Ottawa Amateur Radio Club PI and PI2 interface.
	
	<tt/plip.c/ - Parallel Line Internet Protocol, allows two
	computers to send packets to each other over two joined
	parallel ports in a point-to-point fashion.

	<tt/ppp.c/ - Point-to-Point Protocol (RFC1331), for the
	Transmission of Multi-protocol Datagrams over a
	Point-to-Point Link (again usually modems).

	<tt/slip.c/ - Serial Line Internet Protocol, allows two
	computers to send packets to each other over two joined
	serial ports (usually via modems) in a point-to-point fashion.

	<tt/tunnel.c/ - Provides an IP tunnel through which you can
	tunnel network traffic transparently across subnets

	<tt/wavelan.c/ - An Ethernet-like radio transceiver
	controlled by the Intel 82586 coprocessor which is used on
	other ethercards such as the Intel EtherExpress.

	Note that there are a few cards out there with `on-board termination'.
	These cards have a jumper which when closed, puts a 50 ohm resistor
	across the BNC input. With these cards, you can use a BNC T and
	terminator like normal, or put the cable directly onto the card
	and close the jumper to enable the on-board termination.

	Any bus-master will have problems with other bus-masters
	that are bus-hogs, such as some primitive SCSI adaptors. A few
	badly-designed motherboard chipsets have problems with
	bus-masters. And a reason for not using <em/any/ type of
	DMA device is using a 486 processor designed for
	plug-in replacement of a 386: these processors must
	flush their cache with each DMA cycle. (This includes
	the Cx486DLC, Ti486DLC, Cx486SLC, Ti486SLC, etc.)

	There are some NE2000 clone ethercards out there that are waiting black
	holes for autoprobe drivers. While many NE2000 clones are
	safe until they are enabled, some can't be reset to a safe mode.
	These dangerous ethercards will hang any I/O access to their
	`dataports'. The typical dangerous locations are:
<code>
        Ethercard jumpered base     Dangerous locations (base + 0x10 - 0x1f)
                0x300 *                         0x310-0x317
                0x320                           0x330-0x337
                0x340                           0x350-0x357
                0x360                           0x370-0x377
</code>

	* The 0x300 location is the traditional place to put an ethercard, but
	it's also a popular place to put other devices (often SCSI
	controllers). The 0x320 location is often the next one chosen, but
	that's bad for for the AHA1542 driver probe. The 0x360 location is
	bad, because it conflicts with the parallel port at 0x378.
	If you have two IDE controllers, or two floppy controlers, then
	<tt/0x360/ is also a bad choice, as a NE2000 card will clobber
	them as well.

	Note that kernels > 1.1.7X keep a log of who uses
	which I/O ports, and will not let a driver use I/O ports registered
	by an earlier driver. This may result in probes silently failing.
	You can view who is using what I/O ports by typing
	<tt>cat /proc/ioports</tt> if you have the proc filesystem enabled.

	To avoid these lurking ethercards, here are the things you can do:

<itemize>

<item>	Probe for the device's BIOS in memory space. This is easy
	and always safe, but it only works for cards that always have
	BIOSes, like primary SCSI controllers.

<item>	Avoid probing any of the above locations until you think
	you've located your device. The NE2000 clones have a reset range
	from <base>+0x18 to <base>+0x1f that
	will read as 0xff, so probe
	there first if possible. It's also safe to probe in the 8390
	space at <base>+0x00 - <base>+0x0f, but that area
	will return quasi-random values

<item>	If you must probe in the dangerous range, for instance if your
	target device has only a few port locations, first check that
	there isn't an NE2000 there. You can see how to do this by
	looking at the probe code in /usr/src/linux/net/inet/ne.c

<item>	Use the `reserve' boot time argument to protect volatile
	areas from being probed. See the information on using boot
	time arguments with LILO in
	<ref id="reserve" name="The reserve command">

</itemize>

<sect1>Writing a Driver<label id="skel">
<p>

	The only thing that one needs to use an ethernet card with Linux
	is the appropriate driver. For this, it is essential that the
	manufacturer will release the technical programming information to
	the general public without you (or anyone) having to sign your life
	away. A good guide for the likelihood of getting documentation
	(or, if you aren't writing code, the likelihood that someone
	else will write that driver you really, really need) is the
	availability of the Crynwr (nee Clarkson) packet driver. Russ
	Nelson runs this operation, and has been very helpful in supporting
	the development of drivers for Linux. <em/Net-surfers/ can try this
	URL to look up Russ' software.

	<url url="http://www.crynwr.com/crynwr/home.html"
		name="Russ Nelson's Packet Drivers">

	Given the documentation, you can write a driver for
	your card and use it for Linux (at least in theory).
	Keep in mind that some old hardware that was designed for XT type
	machines will not function very well in a multitasking
	environment such as Linux. Use of these will lead to major
	problems if your network sees a reasonable amount of traffic.

	Most cards come with drivers for MS-DOS interfaces such as
	NDIS and ODI, but these are useless for Linux. Many people
	have suggested directly linking them in or automatic
	translation, but this is nearly impossible. The MS-DOS
	drivers expect to be in 16 bit mode and hook into `software
	interrupts', both incompatible with the Linux kernel. This
	incompatibility is actually a feature, as some Linux drivers
	are considerably better than their MS-DOS counterparts. The
	`8390' series drivers, for instance, use ping-pong transmit
	buffers, which are only now being introduced in the MS-DOS world.

	(Ping-pong Tx buffers means using at least 2 max-size
	packet buffers for Tx packets. One is loaded while the card
	is transmitting the other. The second is then sent as soon
	as the first finished, and so on. In this way, most cards
	are able to continuously send back-to-back packets onto
	the wire.)

	OK. So you have decided that you want to write a driver for the
	Foobar Ethernet card, as you have the programming information,
	and it hasn't been done yet. (...these are the two main
	requirements ;-) You should start with the skeleton
	network driver that is provided
	with the Linux kernel source tree. It can be found in the file
	/usr/src/linux/drivers/net/skeleton.c in all recent kernels.
	Also have a look at the Kernel Hackers Guide, at the
	following URL:
	<url url="http://www.redhat.com:8080/HyperNews/get/khg.html"
		name="KHG">


<sect1>Driver interface to the kernel
<p>

	Here are some notes on the functions that you would have to
	write if creating a new driver. Reading this in conjunction
	with the above skeleton driver may help clear things up.


<sect2>Probe
<p>

	Called at boot to check for existence of card. Best if it
	can check un-obtrsively by reading from memory, etc. Can
	also read from I/O ports. Initial writing to I/O ports in a probe
	is <em/not good/ as it may kill another device.
	Some device initialization is usually done here (allocating
	I/O space, IRQs,filling in the dev->??? fields etc.)
	You need to know what io ports/mem the card can be
	configured to, how to enable shared memory (if used)
	and how to select/enable interrupt generation, etc.

<sect2>Interrupt handler
<p>

	Called by the kernel when the card posts an interrupt.
	This has the job of determining why the card posted
	an interrupt, and acting accordingly. Usual interrupt
	conditions are data to be rec'd, transmit completed,
	error conditions being reported. You need to know
	any relevant interrupt status bits so that you can
	act accordingly.

<sect2>Transmit function
<p>

	Linked to dev->hard_start_xmit() and is called by the
	kernel when there is some data that the kernel wants
	to put out over the device. This puts the data onto
	the card and triggers the transmit. You need to
	know how to bundle the data and how to get it onto the
	card (shared memory copy, PIO transfer, DMA?) and in
	the right place on the card. Then you need to know
	how to tell the card to send the data down the wire, and
	(possibly) post an interrupt when done.
	When the hardware can't accept additional packets it should set
	the dev->tbusy flag. When additional room is available, usually
	during a transmit-complete interrupt, dev->tbusy should be cleared
	and the higher levels informed with <tt/mark_bh(INET_BH)/.

<sect2>Receive function
<p>

	Called by the kernel interrupt handler when the card reports
	that there is data on the card. It pulls the data off
	the card, packages it into a sk_buff and lets the
	kernel know the data is there for it by doing a
	netif_rx(sk_buff). You need to know how to enable
	interrupt generation upon Rx of data, how to check any
	relevant Rx status bits, and how to get that data off the
	card (again sh mem, PIO, DMA, etc.)

<sect2>Open function
<p>

	linked to dev->open and called by the networking layers
	when somebody does <tt/ifconfig eth0 up/ - this
	puts the device on line and enables it for Rx/Tx of
	data. Any special initialization incantations that were
	not done in the probe sequence (enabling IRQ generation, etc.)
	would go in here.

<sect2>Close function (optional)
<p>

	This puts the card in a sane state when someone
	does <tt/ifconfig eth0 down/.
	It should free the IRQs and DMA channels if the hardware permits,
        and turn off anything that will save power (like the transceiver).

<sect2>Miscellaneous functions
<p>

	Things like a reset function, so that if things go south,
	the driver can try resetting the card as a last ditch effort.
	Usually done when a Tx times out or similar. Also a function
	to read the statistics registers of the card if so equipped.

<sect1>Technical information from 3Com<label id="3com-tech">
<p>

	If you are interested in working on drivers for 3Com cards,
	you can get technical documentation from 3Com. Cameron has
	been kind enough to tell us how to go about it below:

	3Com's Ethernet Adapters are documented for driver writers
	in our `Technical References' (TRs). These manuals describe
	the programmer interfaces to the boards but they don't talk
	about the diagnostics, installation programs, etc that end
	users can see.
	
	The Network Adapter Division marketing department has the
	TRs to give away. To keep this program efficient, we
	centralized it in a thing called `CardFacts.' CardFacts is
	an automated phone system. You call it with a touch-tone
	phone and it faxes you stuff. To get a TR, call CardFacts
	at 408-727-7021. Ask it for Developer's Order Form,
	document number 9070. Have your fax number ready when you
	call. Fill out the order form and fax it to 408-764-5004.
	Manuals are shipped by Federal Express 2nd Day Service.
	
	There are people here who think we are too free with the
	manuals, and they are looking for evidence that the system
	is too expensive, or takes too much time and effort.
	So far, 3Com customers have been really good about
	this, and there's no problem with the level of requests
	we've been getting. We need your continued cooperation and
	restraint to keep it that way.
	
<sect1>Notes on AMD PCnet / LANCE Based cards<label id="amd-notes">
<p>

	The AMD LANCE (Local Area Network Controller for Ethernet)
	was the original offering, and has since been replaced by
	the `PCnet-ISA' chip, otherwise known as the 79C960.
	Note that the name `LANCE'
	has stuck, and some people will refer to the new chip by the old
	name. Dave Roberts of the Network Products Division of AMD was kind
	enough to contribute the following information regarding this chip:

	`Functionally, it is equivalent to a NE1500. The register set
	is identical to the old LANCE with the 1500/2100 architecture
	additions. Older 1500/2100 drivers will work on the PCnet-ISA.
	The NE1500 and NE2100 architecture is basically the same.
	Initially Novell called it the 2100, but then tried to distinguish
	between coax and 10BASE-T cards. Anything that was 10BASE-T only was
	to be numbered in the 1500 range. That's the only difference.

	Many companies offer PCnet-ISA based products, including HP,
	Racal-Datacom, Allied Telesis, Boca Research, Kingston Technology, etc.
	The cards are basically the same except that some manufacturers
	have added `jumperless' features that allow the card to
	be configured in software. Most have not. AMD offers a standard
	design package for a card that uses the PCnet-ISA and many
	manufacturers use our design without change.
	What this means is that anybody who wants to write drivers for
	most PCnet-ISA based cards can just get the data-sheet from AMD. Call
	our literature distribution center at (800)222-9323 and ask for the
	Am79C960, PCnet-ISA data sheet. It's free.

	A quick way to understand whether the card is a `stock' card
	is to just look at it. If it's stock, it should just have one large
	chip on it, a crystal, a small IEEE address PROM, possibly a socket
	for a boot ROM, and a connector (1, 2, or 3, depending on the media
	options offered). Note that if it's a coax card, it will have some
	transceiver stuff built onto it as well, but that should be near the
	connector and away from the PCnet-ISA.'

	A note to would-be card hackers is that different LANCE
	implementations do `restart' in different ways. Some pick up
	where they left off in the ring, and others start right from
	the beginning of the ring, as if just initialised.

<sect1>Multicast and Promiscuous Mode<label id="promisc">
<p>

	Another one of the things Donald has worked on is
	implementing multicast and promiscuous mode hooks.
	All of the <em/released/ (i.e. <bf/not/ ALPHA) ISA drivers
	now support promiscuous mode.

	Donald writes:
	`I'll start by discussing promiscuous mode, which is
	conceptually easy to implement. For most hardware you
	only have to set a register bit, and from then on you get
	every packet on the wire. Well, it's almost that easy;
	for some hardware you have to shut the board (potentially
	dropping a few packet), reconfigure it, and then re-enable
	the ethercard.
	OK, so that's easy, so I'll move on something that's not
	quite so obvious: Multicast. It can be done two ways:
	
<enum>

<item>	Use promiscuous mode, and a packet filter like the
	Berkeley packet filter (BPF). The BPF is a pattern matching
	stack language, where you write a program that picks out the
	addresses you are interested in. Its advantage is that it's
	very general and programmable. Its disadvantage is that there
	is no general way for the kernel to avoid turning on promiscuous
	mode and running every packet on the wire through every registered
	packet filter. See <ref id="bpf" name="The Berkeley Packet Filter">
	for more info.
	
<item>	Using the built-in multicast filter that most etherchips have.

</enum>
	
	I guess I should list what a few ethercards/chips provide:

<verb>
	
	Chip/card  Promiscuous  Multicast filter
	----------------------------------------
	Seeq8001/3c501  Yes     Binary filter (1)
	3Com/3c509      Yes     Binary filter (1)
	8390            Yes     Autodin II six bit hash (2) (3)
	LANCE           Yes     Autodin II six bit hash (2) (3)
	i82586          Yes     Hidden Autodin II six bit hash (2) (4)
	
</verb>

<enum>

<item>	These cards claim to have a filter, but it's a simple
	yes/no `accept all multicast packets', or `accept no
	multicast packets'.

<item>	AUTODIN II is the standard ethernet CRC (checksum)
	polynomial. In this scheme multicast addresses are hashed
	and looked up in a hash table. If the corresponding bit
	is enabled, this packet is accepted. Ethernet packets are
	laid out so that the hardware to do this is trivial -- you
	just latch six (usually) bits from the CRC circuit (needed
	anyway for error checking) after the first six octets (the
	destination address), and use them as an index into the
	hash table (six bits -- a 64-bit table).
	
<item>	These chips use the six bit hash, and must have the
	table computed and loaded by the host. This means the
	kernel must include the CRC code.
	
<item>	The 82586 uses the six bit hash internally, but it
	computes the hash table itself from a list of multicast
	addresses to accept.

</enum>

	Note that none of these chips do perfect filtering, and we
	still need a middle-level module to do the final
	filtering. Also note that in every case we must keep a
	complete list of accepted multicast addresses to recompute
	the hash table when it changes.
	
<sect1>The Berkeley Packet Filter (BPF)<label id="bpf">
<p>

	The general idea of the developers is
	that the BPF functionality should not be provided
	by the kernel, but should be in a (hopefully little-used)
	compatibility library.
	
	For those not in the know: BPF (the Berkeley Packet Filter)
	is an mechanism for specifying to the kernel networking layers
	what packets you are interested in. It's implemented as a
	specialized stack language interpreter built into a low level
	of the networking code. An application passes a program
	written in this language to the kernel, and the kernel runs the
	program on each incoming packet. If the kernel has multiple
	BPF applications, each program is run on each packet.
	
	The problem is that it's difficult to deduce what kind of
	packets the application is really interested in from the packet
	filter program, so the general solution is to always run the
	filter. Imagine a program that registers a BPF program to
	pick up a low data-rate stream sent to a multicast address.
	Most ethernet cards have a hardware multicast address filter
	implemented as a 64 entry hash table that ignores most unwanted
	multicast packets, so the capability exists to make this a very
	inexpensive operation. But with the BPF the kernel must switch
	the interface to promiscuous mode, receive _all_ packets, and
	run them through this filter. This is work, BTW, that's very
	difficult to account back to the process requesting the packets.
