-
-I   OVERVIEW
-
-    The 3c90X series ethernet cards are a group of high-performance busmaster
-    DMA cards from 3Com.  This particular driver supports both the 3c90x and
-    the 3c90xB revision cards.  3C90xC family support has been tested to some
-    degree but not extensively.
-

-    documentation "3c90x.txt" before compiling and using this driver.
-
-
-II  FLASH PROMS
-
-    The 3c90xB cards, according to the 3Com documentation, only accept the
-    following flash memory chips:
-
-	Atmel AT29C512 (64 kilobyte)
-	Atmel AT29C010 (128 kilobyte)
-
-    The 3c90x cards, according to the 3Com documentation, accept the
-    following flash memory chips capacities:
-
-	64  kb (8 kB)
-	128 kb (16 kB)
-	256 kb (32 kB) and
-	512 kb (64 kB)
-
-    Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
-    adapters, but flashing on the 3c905b cards would only be supported
-    through the Atmel parts.  Any device, of the supported size, should
-    be supported when programmed by a dedicated PROM programmer (e.g.
-    not the card).
-
-    To use this driver in such a PROM, visit Atmel's web site and download
-    their .PDF file containing a list of their distributors.  Contact the
-    distributors for pricing information.  The prices are quite reasonable
-    (about $3 US each for the 64 kB part), and are comparable to what one would
-    expect for similarly sized standard EPROMs.  And, the flash chips are much
-    easier to work with, as they don't need to be UV-erased to be reprogrammed.
-    The 3C905B card actually provides a method to program the flash memory
-    while it is resident on board the card itself; if someone would like to
-    write a small DOS program to do the programming, I can provide the
-    information about the registers and so forth.
-
-    A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
-    directory that allows for the on-board flashing of the ROM while Linux
-    is running.  The program has been successfully used under Linux, but I
-    have heard problem reports of its use under FreeBSD.  Anyone willing to
-    make it work under FreeBSD is more than welcome to do so!
-
-    You also have the option of using EPROM chips - the 3C905B-TX-NM has been
-    successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
-    specified access time of 100ns and faster.
-
-
-III GENERAL USE
-
-    Normally, the basic procedure for using this driver is as follows:
-
-	1.  Run the 3c90xcfg program on the driver diskette to enable the
-	boot PROM and set it to 64k or 128k, as appropriate.
-	2.  Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
-	possibly the value CFG_3C90X_XCVR defined to the transceiver type that
-	you want to use (i.e., 10/100 rj45, AUI, coax, MII).
-	3.  Run the floppy image on the PC to be network booted, to get
-	it configured, and to verify that it will boot properly.
-	4.  Build the 3c90x.rom or 3c90x.lzrom PROM image and program
-	it into the flash or EPROM memory chip.
-	5.  Put the PROM in the ethernet card, boot and enable 'boot from
-	network first' in the system BIOS, save and reboot.
-
-    Here are some issues to be aware of:
-
-	1.  If you experience crashes or different behaviour when using the
-	boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
-	steps 2-5 above.  This works around a bug in some 3c905B cards (see
-	below), but has some side-effects which may not be desirable.
-        Please note that you have to boot off a floppy (not PROM!) once for
-        this fix to take effect.
-	2.  The possible need to manually set the CFG_3C90X_XCVR value to
-	configure the transceiver type.  Values are listed below.
-	3.  The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
-	operating systems that don't intelligently determine the
-	transceiver type.
-
-    Some things that are on the 'To-Do' list, perhaps for me, but perhaps
-    for any other volunteers out there:
-
-	1.  Extend the driver to fully implement the auto-select
-	algorithm if the card has multiple media ports.
-	2.  Fix any bugs in the code <grin>....
-	3.  Extend the driver to support the 3c905c revision cards
-	"officially".  Right now, the support has been primarily empirical
-	and not based on 3c905C documentation.
-
-    Now for the details....
-
-    This driver has been tested on roughly 300 systems.  The main two
-    configuration issues to contend with are:
-
-	1.  Ensure that PCI Busmastering is enabled for the adapter (configured
-	in the CMOS setup)
-	2.  Some systems don't work properly with the adapter when plug and
-	play OS is enabled; I always set it to "No" or "Disabled" -- this makes
-	it easier and really doesn't adversely affect anything.
-
-    Roughly 95% of the systems worked when configured properly.  A few
-    have issues with booting locally once the boot PROM has been installed
-    (this number has been less than 2%).  Other configuration issues that
-    to check:
-
-	1.  Newer BIOS's actually work correctly with the network boot order.
-	Set the network adapter first.  Most older BIOS's automatically go to
-	the network boot PROM first.
-	2.  For systems where the adapter was already installed and is just
-	having the PROM installed, try setting the "reset configuration data"
-	to yes in the CMOS setup if the BIOS isn't seen at first.  If your BIOS
-	doesn't have this option, remove the card, start the system, shut down,
-	install the card and restart (or switch to a different PCI slot).
-	3.  Make sure the CMOS security settings aren't preventing a boot.
-
-    The 3c905B cards have a significant 'bug' that relates to the flash prom:
-    unless the card is set internally to the MII transceiver, it will only
-    read the first 8k of the PROM image.  Don't ask why -- it seems really
-    obscure, but it has to do with the way they mux'd the address lines
-    from the PCI bus to the ROM.  Unfortunately, most of us are not using
-    MII transceivers, and even the .lzrom image ends up being just a little
-    bit larger than 8k.  Note that the workaround for this is disabled by
-    default, because the Windows NT 4.0 driver does not like it (no packets
-    are transmitted).
-
-    So, the solution that I've used is to internally set the card's nvram
-    configuration to use MII when it boots.  The 3c905b driver does this
-    automatically.  This way, the 16k prom image can be loaded into memory,
-    and then the 3c905b driver can set the temporary configuration of the
-    card to an appropriate value, either configurable by the user or chosen
-    by the driver.
-
-    To enable the 3c905B bugfix, which is necessary for these cards when 
-    booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
-    create a floppy image and boot it once.
-    Thereafter, the card should accept the larger prom image.
-
-    The driver should choose an appropriate transceiver on the card.  However,
-    if it doesn't on your card or if you need to, for instance, set your
-    card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
-    which transceiver you want to use.  To do this, build the 3c905b.fd0
-    image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
-    values:
-
-	0	10Base-T
-	1	10mbps AUI
-	3	10Base-2 (thinnet/coax)
-	4	100Base-TX
-	5	100Base-FX
-	6	MII
-	8	Auto-negotiation 10Base-T / 100Base-TX (usually the default)
-	9	MII External MAC Mode
-	255	Allow driver to choose an 'appropriate' media port.
-
-    Then proceed from step 2 in the above 'general use' instructions.  The
-    .rom image can be built with CFG_3C90X_XCVR set to a value, but you
-    normally don't want to do this, since it is easier to change the
-    transceiver type by rebuilding a new floppy, changing the BIOS to floppy
-    boot, booting, and then changing the BIOS back to network boot.  If
-    CFG_3C90X_XCVR is not set in a particular build, it just uses the
-    current configuration (either its 'best guess' or whatever the stored
-    CFG_3C90X_XCVR value was from the last time it was set).
-
-    [[ Note for the more technically inclined:  The CFG_3C90X_XCVR value is
-    programmed into a register in the card's NVRAM that was reserved for
-    LanWorks PROM images to use.  When the driver boots, the card comes
-    up in MII mode, and the driver checks the LanWorks register to find
-    out if the user specified a transceiver type.  If it finds that
-    information, it uses that, otherwise it picks a transceiver that the
-    card has based on the 3c905b's MediaOptions register.  This driver isn't
-    quite smart enough to always determine which media port is actually
-    _connected_; maybe someone else would like to take on that task (it
-    actually involves sending a self-directed packet and seeing if it
-    comes back.  IF it does, that port is connected). ]]
-
-    Another issue to keep in mind is that it is possible that some OS'es
-    might not be happy with the way I've handled the PROM-image hack with
-    setting MII mode on bootup.  Linux 2.0.35 does not have this problem.
-    Behavior of other systems may vary.  The 3com documentation specifically
-    says that, at least with the card that I have, the device driver in the
-    OS should auto-select the media port, so other drivers should work fine
-    with this 'hack'.  However, if yours doesn't seem to, you can try defining
-    CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
-    working setting (that allowed the bootp/tftp process) across the eth_reset
-    operation.
-
-
-IV  FOR DEVELOPERS....
-
-    If you would like to fix/extend/etc. this driver, feel free to do so; just
-    be sure you can test the modified version on the 3c905B-TX cards that the
-    driver was originally designed for.  This section of this document gives
-    some information that might be relevant to a programmer.
-
-    A.  Main Entry Point
-
-	a3c90x_probe is the main entry point for this driver.  It is referred
-	to in an array in 'config.c'.
-
-    B.  Other Important Functions
-
-	The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
-	a3c90x_disable are static functions that EtherBoot finds out about
-	as a  result of a3c90x_probe setting entries in the nic structure
-	for them.  The EtherBoot framework does not use interrupts.  It is
-	polled.  All transmit and receive operations are initiated by the
-	etherboot framework, not by an interrupt or by the driver.
-
-    C.  Internal Functions
-
-	The following functions are internal to the driver:
-
-	a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
-	a3c90x_internal_SetWindow - shifts between one of eight register
-	windows onboard the 3c90x.  The bottom 16 bytes of the card's
-	I/O space are multiplexed among 128 bytes, only 16 of which are
-	visible at any one time.  This SetWindow function selects one of
-	the eight sets.
-	a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
-	card's onboard nvram.  This is NOT the BIOS boot rom.  This is
-	where the card stores such things as its hardware address.
-	a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
-	card's nvram, and recomputes the eeprom checksum.
-	a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
-	card's nvram.  Used by the above routine.
-	a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
-	card's nvram.  Used by the above routine.
-
-    D.  Globals
-
-	All global variables are inside a global structure named INF_3C90X.
-	So, wherever you see that structure referenced, you know the variable
-	is a global.  Just keeps things a little neater.
-
-    E.  Enumerations
-
-	There are quite a few enumerated type definitions for registers and
-	so forth, many for registers that I didn't even touch in the driver.
-	Register types start with 'reg', window numbers (for SetWindow)
-	start with 'win', and commands (for IssueCommand) start with 'cmd'.
-	Register offsets also include an indication in the name as to the
-	size of the register (_b = byte, _w = word, _l = long), and which
-	window the register is in, if it is windowed (0-7).
-
-    F.  Why the 'a3c90x' name?
-
-	I had to come up with a letter at the beginning of all of the
-	identifiers, since 3com so conveniently had their name start with a
-	number.  Another driver used 't' (for 'three'?); I chose 'a' for
-	no reason at all.
-
-Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
-working around the 3C905 hardware bug mentioned above:
-
-Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
-that fail to load and run the boot program the first time around. If
-they have a "Lucent" rather than a "Broadcom" chipset these cards have
-a configuration bug that causes a hang when trying to load the boot
-program from the PROM, if you try to use them right out of the box.
-
-The boot program in this floppy is the file named 3c905b-tpo100.rom
-from Etherboot version 4.6.10, compiled with the bugfix parameter
-
-			CFG_3C90X_BOOTROM_FIX
-
-You have to take the chip off the card and boot the system once using
-this floppy. Once loaded from the floppy, the boot program will access
-the card and change some setting in it, correcting the problem. After
-that you may use either this boot program or the normal one, compiled
-without this bugfix parameter, to boot the machine from the PROM chip.
-
-[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

-  Permission is granted to distribute the enclosed cs89x0.[ch] driver
-  only in conjunction with the Etherboot package.  The code is
-  ordinarily distributed under the GPL.
-  
-  Russ Nelson, January 2000
-
-  ChangeLog:
-
-  Thu Dec 6 22:40:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * disabled all "advanced" features; this should make the code more reliable
-
-  * reorganized the reset function
-
-  * always reset the address port, so that autoprobing will continue working
-
-  * some cosmetic changes
-
-  * 2.5
-
-  Thu Dec 5 21:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * tested the code against a CS8900 card
-
-  * lots of minor bug fixes and adjustments
-
-  * this is the first release, that actually works! it still requires some
-    changes in order to be more tolerant to different environments
-
-  * 4
-
-  Fri Nov 22 23:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * read the manuals for the CS89x0 chipsets and took note of all the
-    changes that will be neccessary in order to adapt Russel Nelson's code
-    to the requirements of a BOOT-Prom
-
-  * 6
-
-  Thu Nov 19 22:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * Synched with Russel Nelson's current code (v1.00)
-
-  * 2
-
-  Thu Nov 12 18:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * Cleaned up some of the code and tried to optimize the code size.
-
-  * 1.5
-
-  Sun Nov 10 16:30:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
-
-  * First experimental release. This code compiles fine, but I
-  have no way of testing whether it actually works.
-
-  * I did not (yet) bother to make the code 16bit aware, so for
-  the time being, it will only work for Etherboot/32.

-  * 12

-    This driver is written for the Digital Equipment Corporation series

-    	DE100

-	DE201 Turbo
-	DE202 Turbo (TP BNC)
-	DE210
-	DE422       (EISA)
-
-    The  driver has been tested on DE100, DE200 and DE202 cards  in  a
-    relatively busy network. The DE422 has been tested a little.
-
-    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of
-    cards,  since they have  a  new custom ASIC in   place of the AMD  LANCE
-    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
-    those cards.
-
-    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
-    a DECstation 5000/200.

-    The  driver was originally based  on   the 'lance.c' driver from  Donald
-    Becker   which  is included with  the  standard  driver distribution for
-    linux.  V0.4  is  a complete  re-write  with only  the kernel  interface

-
-    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
-    driver.
-
-    The original DEPCA  card requires that the  ethernet ROM address counter
-    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
-    only  done when a  0x08 is read as the  first address octet (to minimise
-    the chances  of writing over some  other hardware's  I/O register).  The
-    NICSR accesses   have been changed  to  byte accesses  for all the cards
-    supported by this driver, since there is only one  useful bit in the MSB
-    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
-    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
-    help debugging all this (and holding my feet to  the fire until I got it
-    right).
-
-    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
-    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
-    mode which has not  been implemented in  this driver (only the 32kB  and
-    64kB modes are supported [16kB/48kB for the original DEPCA]).
-
-    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
-    there is only provision  for two I/O base addresses  on each card (0x300
-    and 0x200). The I/O address is detected by searching for a byte sequence
-    in the Ethernet station address PROM at the expected I/O address for the
-    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
-    looking  for the self  test PROM  and detecting the  card name.   When a
-    second  DEPCA is  detected,  information  is   placed in the   base_addr
-    variable of the  next device structure (which  is created if necessary),
-    thus  enabling ethif_probe  initialization  for the device.  More than 2
-    EISA cards can  be  supported, but  care will  be  needed assigning  the
-    shared memory to ensure that each slot has the  correct IRQ, I/O address
-    and shared memory address assigned.
-
-    ************************************************************************
-
-    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
-    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
-    then 0x200.  The  base memory address for  the first device must be less
-    than that of the second so that the auto probe will correctly assign the
-    I/O and memory addresses on the same card.  I can't think of a way to do
-    this unambiguously at the moment, since there is nothing on the cards to
-    tie I/O and memory information together.
-
-    I am unable  to  test  2 cards   together for now,    so this  code   is
-    unchecked. All reports, good or bad, are welcome.
-
-    ************************************************************************
-
-    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
-    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
-    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
-    really IRQ9 in machines with 16 IRQ lines.
-
-    No 16MB memory  limitation should exist with this  driver as DMA is  not
-    used and the common memory area is in low memory on the network card (my
-    current system has 20MB and I've not had problems yet).
-
-    The ability to load this driver as a loadable module has been added. To
-    utilise this ability, you have to do <8 things:
-
-    0) have a copy of the loadable modules code installed on your system.
-    1) copy depca.c from the  /linux/drivers/net directory to your favourite
-    temporary directory.
-    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
-    address and IRQ you're using (see also 5).
-    3) compile  depca.c, but include -DMODULE in  the command line to ensure
-    that the correct bits are compiled (see end of source code).
-    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
-    kernel with the depca configuration turned off and reboot.
-    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
-       [Alan Cox: Changed the code to allow command line irq/io assignments]
-       [Dave Davies: Changed the code to allow command line mem/name
-                                                                assignments]
-    6) run the net startup bits for your eth?? interface manually 
-    (usually /etc/rc.inet[12] at boot time). 
-    7) enjoy!
-
-    Note that autoprobing is not allowed in loadable modules - the system is
-    already up and running and you're messing with interrupts.
-
-    To unload a module, turn off the associated interface 
-    'ifconfig eth?? down' then 'rmmod depca'.
-
-    To assign a base memory address for the shared memory  when running as a
-    loadable module, see 5 above.  To include the adapter  name (if you have
-    no PROM  but know the card name)  also see 5  above. Note that this last
-    option  will not work  with kernel  built-in  depca's. 
-
-    The shared memory assignment for a loadable module  makes sense to avoid
-    the 'memory autoprobe' picking the wrong shared memory  (for the case of
-    2 depca's in a PC).
-
-    ************************************************************************
-    Support for MCA EtherWORKS cards added 11-3-98.
-    Verified to work with up to 2 DE212 cards in a system (although not
-      fully stress-tested).  
-
-    Currently known bugs/limitations:
-
-    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
-           not the command line for IRQ and memory address.  You can
-           specify them if you want, but it will throw your values out.
-           You still have to pass the IO address it was configured as
-           though.

-/**************************************************************************
-Etherboot -  BOOTP/TFTP Bootstrap Program
-Intel EEPRO/10 NIC driver for Etherboot
-Adapted from Linux eepro.c from kernel 2.2.17
-
-This board accepts a 32 pin EEPROM (29C256), however a test with a
-27C010 shows that this EPROM also works in the socket, but it's not clear
-how repeatably. The two top address pins appear to be held low, thus
-the bottom 32kB of the 27C010 is visible in the CPU's address space.
-To be sure you could put 4 copies of the code in the 27C010, then
-it doesn't matter whether the extra lines are held low or high, just
-hopefully not floating as CMOS chips don't like floating inputs.
-
-Be careful with seating the EPROM as the socket on my board actually
-has 34 pins, the top row of 2 are not used.

-  command.
-
-  To complete the memory setup you only have to write the station address at
-  SA_OFFSET and create the Tx & Rx buffer lists.
-
-  The Tx command chain and buffer list is setup as follows:
-  A Tx command table, with the data buffer pointing to...
-  A Tx data buffer descriptor.  The packet is in a single buffer, rather than
-	chaining together several smaller buffers.
-  A NoOp command, which initially points to itself,
-  And the packet data.
-
-  A transmit is done by filling in the Tx command table and data buffer,
-  re-writing the NoOp command, and finally changing the offset of the last
-  command to point to the current Tx command.  When the Tx command is finished,
-  it jumps to the NoOp, when it loops until the next Tx command changes the
-  "link offset" in the NoOp.  This way the 82586 never has to go through the
-  slow restart sequence.
-
-  The Rx buffer list is set up in the obvious ring structure.  We have enough
-  memory (and low enough interrupt latency) that we can avoid the complicated
-  Rx buffer linked lists by alway associating a full-size Rx data buffer with
-  each Rx data frame.
-
-  I currently use one transmit buffer starting at TX_BUF_START (0x0100), and
-  use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

-  Etherboot DEC Tulip driver
-  adapted by Ken Yap from

-  FreeBSD netboot DEC 21143 driver
-
-  Author: David Sharp
-    date: Nov/98
-
- Known to work on DEC DE500 using 21143-PC chipset.
- Even on cards with the same chipset there can be
- incompatablity problems with the way media selection
- and status LED settings are done.  See comments below.
-
- Some code fragments were taken from verious places,
- Ken Yap's etherboot, FreeBSD's if_de.c, and various
- Linux related files.  DEC's manuals for the 21143 and
- SROM format were very helpful.  The Linux de driver
- development page has a number of links to useful
- related information.  Have a look at:
- ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/tulip-devel.html

-Date:   25 Febrary 2001
-
-Description:
-
-This file is intended to help people who want to write an Etherboot
-driver or port another driver to Etherboot.  It is a starting point.
-Perhaps someday I may write a more detailed description of writing an
-Etherboot driver. This text should help get people started, and
-studying sis900.[ch] should help show the basic structure and
-techniques involved in writing and Etherboot driver.
-
-***********************************************************************

-0. Back up all the files I need to modify:
-
-cd etherboot-4.7.20/src
-cp Makefile Makefile.orig
-cp config.c config.c.orig
-cp pci.h pci.h.orig
-cp NIC NIC.orig
-cp cards.h cards.h.orig
-
-1. Edit src/Makefile to add SIS900FLAGS to defines
-
-SIS900FLAGS=	       	-DINCLUDE_SIS900
-
-2. edit src/pci.h to add PCI signatures for card
-

-/*
- * The Schneider & Koch (SK) G16 Network device driver is based
- * on the 'ni6510' driver from Michael Hipp which can be found at
- * ftp://sunsite.unc.edu/pub/Linux/system/Network/drivers/nidrivers.tar.gz

- *                 A. Cox (A.Cox@swansea.ac.uk)
- *                 M. Hipp (mhipp@student.uni-tuebingen.de)
- *                 R. Bolz (Schneider & Koch, Germany)
- *
- * See README.sk_g16 for details about limitations and bugs for the
- * current version.
- *
- * To Do:
- *        - Support of SK_G8 and other SK Network Cards.
- *        - Autoset memory mapped RAM. Check for free memory and then
- *          configure RAM correctly.
- *        - SK_close should really set card in to initial state.
- *        - Test if IRQ 3 is not switched off. Use autoirq() functionality.
- *          (as in /drivers/net/skeleton.c)
- *        - Implement Multicast addressing. At minimum something like
- *          in depca.c.
- *        - Redo the statistics part.
- *        - Try to find out if the board is in 8 Bit or 16 Bit slot.
- *          If in 8 Bit mode don't use IRQ 11.
- *        - (Try to make it slightly faster.)

- * SK_G16 RAM
- *
- * The components are memory mapped and can be set in a region from
- * 0x00000 through 0xfc000 in 16KB steps.
- *
- * The Network components are: dual ported RAM, Prom, I/O Reg, Status-,
- * Controlregister and I/O Command.
- *
- * dual ported RAM: This is the only memory region which the LANCE chip
- *      has access to. From the Lance it is addressed from 0x0000 to
- *      0x3fbf. The host accesses it normally.
- *
- * PROM: The PROM obtains the ETHERNET-MAC-Address. It is realised as a
- *       8-Bit PROM, this means only the 16 even addresses are used of the
- *       32 Byte Address region. Access to a odd address results in invalid
- *       data.
- *
- * LANCE I/O Reg: The I/O Reg is build of 4 single Registers, Low-Byte Write,
- *       Hi-Byte Write, Low-Byte Read, Hi-Byte Read.
- *       Transfer from or to the LANCE is always in 16Bit so Low and High
- *       registers are always relevant.
- *
- *       The Data from the Readregister is not the data in the Writeregister!!
- *
- * Port: Status- and Controlregister.
- *       Two different registers which share the same address, Status is
- *       read-only, Control is write-only.
- *
- * I/O Command:
- *       Any bitcombination written in here starts the transmission between
- *       Host and LANCE.

+/* There are two ways to manage the TX descriptors on the tigon3.
+ * Either the descriptors are in host DMA'able memory, or they

+ * the same mode, they may not be configured individually.
+ *
+ * The mode we use is controlled by TG3_FLAG_HOST_TXDS in tp->tg3_flags.
+ *
+ * To use host memory TX descriptors:
+ *	1) Set GRC_MODE_HOST_SENDBDS in GRC_MODE register.
+ *	   Make sure GRC_MODE_4X_NIC_SEND_RINGS is clear.
+ *	2) Allocate DMA'able memory.
+ *	3) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to DMA address of memory
+ *	      obtained in step 2
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC.
+ *	   c) Set len field of TG3_BDINFO_MAXLEN_FLAGS to number
+ *            of TX descriptors.  Leave flags field clear.
+ *	4) Access TX descriptors via host memory.  The chip
+ *	   will refetch into local SRAM as needed when producer
+ *	   index mailboxes are updated.
+ *
+ * To use on-chip TX descriptors:
+ *	1) Set GRC_MODE_4X_NIC_SEND_RINGS in GRC_MODE register.
+ *	   Make sure GRC_MODE_HOST_SENDBDS is clear.
+ *	2) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to zero.
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC
+ *	   c) TG3_BDINFO_MAXLEN_FLAGS is don't care.
+ *	3) Access TX descriptors directly in on-chip SRAM
+ *	   using normal {read,write}l().  (and not using
+ *         pointer dereferencing of ioremap()'d memory like
+ *	   the broken Broadcom driver does)
+ *
+ * Note that BDINFO_FLAGS_DISABLED should be set in the flags field of
+ * TG3_BDINFO_MAXLEN_FLAGS of all unused SEND_RCB indices.

- *	Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
- *
- *	v1.1 Dec 20, 1999    - Removed linux version checking
- *			       Patch from Tigran Aivazian. 
- *			     - v1.1 includes Alan's SMP updates.
- *			     - We still have problems on SMP though,
- *			       but I'm looking into that. 
- *			
- *	v1.2 Jan 02, 2000    - Hopefully fixed the SMP deadlock.
- *			     - Removed dependency of HZ being 100.
- *			     - We now allow higher priority timers to 
- *			       overwrite timers like TLAN_TIMER_ACTIVITY
- *			       Patch from John Cagle <john.cagle@compaq.com>.
- *			     - Fixed a few compiler warnings.
- *
- *	v1.3 Feb 04, 2000    - Fixed the remaining HZ issues.
- *			     - Removed call to pci_present(). 
- *			     - Removed SA_INTERRUPT flag from irq handler.
- *			     - Added __init and __initdata to reduce resisdent 
- *			       code size.
- *			     - Driver now uses module_init/module_exit.
- *			     - Rewrote init_module and tlan_probe to
- *			       share a lot more code. We now use tlan_probe
- *			       with builtin and module driver.
- *			     - Driver ported to new net API. 
- *			     - tlan.txt has been reworked to reflect current 
- *			       driver (almost)
- *			     - Other minor stuff
- *
- *	v1.4 Feb 10, 2000    - Updated with more changes required after Dave's
- *	                       network cleanup in 2.3.43pre7 (Tigran & myself)
- *	                     - Minor stuff.
- *
- *	v1.5 March 22, 2000  - Fixed another timer bug that would hang the driver
- *			       if no cable/link were present.
- *			     - Cosmetic changes.
- *			     - TODO: Port completely to new PCI/DMA API
- *			     	     Auto-Neg fallback.
- *
- * 	v1.6 April 04, 2000  - Fixed driver support for kernel-parameters. Haven't
- * 			       tested it though, as the kernel support is currently 
- * 			       broken (2.3.99p4p3).
- * 			     - Updated tlan.txt accordingly.
- * 			     - Adjusted minimum/maximum frame length.
- * 			     - There is now a TLAN website up at 
- * 			       http://tlan.kernel.dk
- *
- * 	v1.7 April 07, 2000  - Started to implement custom ioctls. Driver now
- * 			       reports PHY information when used with Donald
- * 			       Beckers userspace MII diagnostics utility.
- *
- * 	v1.8 April 23, 2000  - Fixed support for forced speed/duplex settings.
- * 			     - Added link information to Auto-Neg and forced
- * 			       modes. When NIC operates with auto-neg the driver
- * 			       will report Link speed & duplex modes as well as
- * 			       link partner abilities. When forced link is used,
- * 			       the driver will report status of the established
- * 			       link.
- * 			       Please read tlan.txt for additional information. 
- * 			     - Removed call to check_region(), and used 
- * 			       return value of request_region() instead.
- *	
- *	v1.8a May 28, 2000   - Minor updates.
- *
- *	v1.9 July 25, 2000   - Fixed a few remaining Full-Duplex issues.
- *	                     - Updated with timer fixes from Andrew Morton.
- *	                     - Fixed module race in TLan_Open.
- *	                     - Added routine to monitor PHY status.
- *	                     - Added activity led support for Proliant devices.
- *
- *	v1.10 Aug 30, 2000   - Added support for EISA based tlan controllers 
- *			       like the Compaq NetFlex3/E. 
- *			     - Rewrote tlan_probe to better handle multiple
- *			       bus probes. Probing and device setup is now
- *			       done through TLan_Probe and TLan_init_one. Actual
- *			       hardware probe is done with kernel API and 
- *			       TLan_EisaProbe.
- *			     - Adjusted debug information for probing.
- *			     - Fixed bug that would cause general debug information 
- *			       to be printed after driver removal. 
- *			     - Added transmit timeout handling.
- *			     - Fixed OOM return values in tlan_probe. 
- *			     - Fixed possible mem leak in tlan_exit 
- *			       (now tlan_remove_one).
- *			     - Fixed timer bug in TLan_phyMonitor.
- *			     - This driver version is alpha quality, please
- *			       send me any bug issues you may encounter.
- *
- *	v1.11 Aug 31, 2000   - Do not try to register irq 0 if no irq line was 
- *			       set for EISA cards.
- *			     - Added support for NetFlex3/E with nibble-rate
- *			       10Base-T PHY. This is untestet as I haven't got
- *			       one of these cards.
- *			     - Fixed timer being added twice.
- *			     - Disabled PhyMonitoring by default as this is
- *			       work in progress. Define MONITOR to enable it.
- *			     - Now we don't display link info with PHYs that
- *			       doesn't support it (level1).
- *			     - Incresed tx_timeout beacuse of auto-neg.
- *			     - Adjusted timers for forced speeds.
- *
- *	v1.12 Oct 12, 2000   - Minor fixes (memleak, init, etc.)
- *
- * 	v1.13 Nov 28, 2000   - Stop flooding console with auto-neg issues
- * 			       when link can't be established.
- *			     - Added the bbuf option as a kernel parameter.
- *			     - Fixed ioaddr probe bug.
- *			     - Fixed stupid deadlock with MII interrupts.
- *			     - Added support for speed/duplex selection with 
- *			       multiple nics.
- *			     - Added partly fix for TX Channel lockup with
- *			       TLAN v1.0 silicon. This needs to be investigated
- *			       further.
- *
- * 	v1.14 Dec 16, 2000   - Added support for servicing multiple frames per.
- * 			       interrupt. Thanks goes to
- * 			       Adam Keys <adam@ti.com>
- * 			       Denis Beaudoin <dbeaudoin@ti.com>
- * 			       for providing the patch.
- * 			     - Fixed auto-neg output when using multiple
- * 			       adapters.
- * 			     - Converted to use new taskq interface.
- *
- * 	v1.14a Jan 6, 2001   - Minor adjustments (spinlocks, etc.)
- *

-This software may be used and distributed according to the terms of
-the GNU Public License, incorporated herein by reference.
-
-This is a tulip and clone driver for Etherboot.  See the revision
-history in the tulip.c file for information on changes.  This version
-of the driver incorporates changes from Bob Edwards and Paul Mackerras
-who cantributed changes to support the TRENDnet TE100-PCIA NIC which
-uses a genuine Intel 21143-PD chipset.  There are also various code
-cleanups to make time-based activities more reliable.
-
-Of course you have to have all the usual Etherboot environment
-(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
-(7.16.99) or later of the tulip.c driver compiled in to support some
-MX98715 based cards.  That file is available at:
-
-  http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
-
-NOTES
-
-I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
-a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
-both 10 and 100 mbits. Other cards based on the tulip family may work as
-well.
-
-These cards are about 20$US, are supported by Linux and now Etherboot,
-and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
-10/100 half/full duplex. It seems like a pretty good value compared to
-some of the pricier cards, and can lower the cost of building/adapting
-thin client workstations substantially while giving a considerable
-performance increase.
-
-On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver 
-lets the card choose the fastest speed it can negotiate with the peer
-device.  On other cards, it chooses 10mbit half-duplex.
-
-I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
-According to the data sheet the MX98715A supports up to 64K (27C512)
-EPROMs, 
-
-I've liberally commented the code and header files in the hope that it
-will help the next person who hacks the code or needs to support some
-tulip clone card, or wishes to add functionality.
-
-Anyway, please test this if you can on your tulip based card, and let
-me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
-know how things go.  I also would appreciate code review by people who
-program.  I'm a strong believer in "another set of eyes".
-

-
