Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

20 Theory of Operation
21
22I. Board Compatibility
23
24This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
25Adapter.
26
27II. Board-specific settings
28
29None -- PC cards are autoconfigured.
30
31III. Driver operation
32
33The 3c574 uses a Boomerang-style interface, without the bus-master capability.
34See the Boomerang driver and documentation for most details.
35
36IV. Notes and chip documentation.
37
38Two added registers are used to enhance PIO performance, RunnerRdCtrl and
39RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the
40count of word (16 bits) reads or writes the driver is about to do to the Rx
41or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card
42translation latency by buffering the I/O operations with an 8 word FIFO.
43Note: No other chip accesses are permitted when this buffer is used.
44
45A second enhancement is that both attribute and common memory space
460x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster
47with *some* PCcard bridges) may be used instead of I/O operations.
48This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
49
50Some slow PC card bridges work better if they never see a WAIT signal.
51This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
52Only do this after testing that it is reliable and improves performance.
53
54The upper five bits of RunnerRdCtrl are used to window into PCcard
55configuration space registers. Window 0 is the regular Boomerang/Odie
56register set, 1-5 are various PC card control registers, and 16-31 are
57the (reversed!) CIS table.
58
59A final note: writing the InternalConfig register in window 3 with an
60invalid ramWidth is Very Bad.

3 A PCMCIA ethernet driver for Asix AX88190-based cards
4
5 The Asix AX88190 is a NS8390-derived chipset with a few nasty
6 idiosyncracies that make it very inconvenient to support with a
7 standard 8390 driver. This driver is based on pcnet_cs, with the
8 tweaked 8390 code grafted on the end. Much of what I did was to
9 clean up and update a similar driver supplied by Asix, which was
10 adapted by William Lee, william@asix.com.tw.

893 This is the chip-specific code for many 8390-based ethernet adaptors.
894 This is not a complete driver, it must be combined with board-specific
895 code such as ne.c, wd.c, 3c503.c, etc.
896
897 Seeing how at least eight drivers use this code, (not counting the
898 PCMCIA ones either) it is easy to break some card by what seems like
899 a simple innocent change. Please contact me or Donald if you think
900 you have found something that needs changing. -- PG
901
902 Changelog:
903
904 Paul Gortmaker : remove set_bit lock, other cleanups.
905 Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
906 ei_block_input() for eth_io_copy_and_sum().
907 Paul Gortmaker : exchange static int ei_pingpong for a #define,
908 also add better Tx error handling.
909 Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
910 Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
911 Paul Gortmaker : tweak ANK's above multicast changes a bit.
912 Paul Gortmaker : update packet statistics for v2.1.x
913 Alan Cox : support arbitary stupid port mappings on the
914 68K Macintosh. Support >16bit I/O spaces
915 Paul Gortmaker : add kmod support for auto-loading of the 8390
916 module by all drivers that require it.
917 Alan Cox : Spinlocking work, added 'BUG_83C690'
918 Paul Gortmaker : Separate out Tx timeout code from Tx path.

949 Read the 4 byte, page aligned 8390 header. *If* there is a

952 Read COUNT bytes from the packet buffer into the skb data area. Start
953 reading from RING_OFFSET, the address as the 8390 sees it. This will always
954 follow the read of the 8390 header.

980 * SMP and the 8390 setup.
981 *
982 * The 8390 isnt exactly designed to be multithreaded on RX/TX. There is
983 * a page register that controls bank and packet buffer access. We guard
984 * this with ei_local->page_lock. Nobody should assume or set the page other
985 * than zero when the lock is not held. Lock holders must restore page 0
986 * before unlocking. Even pure readers must take the lock to protect in
987 * page 0.
988 *
989 * To make life difficult the chip can also be very slow. We therefore can't
990 * just use spinlocks. For the longer lockups we disable the irq the device
991 * sits on and hold the lock. We must hold the lock because there is a dual
992 * processor case other than interrupts (get stats/set multicast list in
993 * parallel with each other and transmit).

3 A PCMCIA token-ring driver for IBM-based cards
4
5 This driver supports the IBM PCMCIA Token-Ring Card.
6 Written by Steve Kipisz, kipisz@vnet.ibm.com or
7 bungy@ibm.net
8
9 Written 1995,1996.
10
11 This code is based on pcnet_cs.c from David Hinds.
12
13 V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
14
15 Linux V2.2.x presented significant changes to the underlying
16 ibmtr.c code. Mainly the code became a lot more organized and
17 modular.
18
19 This caused the old PCMCIA Token Ring driver to give up and go
20 home early. Instead of just patching the old code to make it
21 work, the PCMCIA code has been streamlined, updated and possibly
22 improved.
23
24 This code now only contains code required for the Card Services.
25 All we do here is set the card up enough so that the real ibmtr.c
26 driver can find it and work with it properly.
27
28 i.e. We set up the io port, irq, mmio memory and shared ram
29 memory. This enables ibmtr_probe in ibmtr.c to find the card and
30 configure it as though it was a normal ISA and/or PnP card.
31
32 CHANGES
33
34 v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
35 Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
36
37 v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
38 Updated to version 2.2.7 to match the first version of the kernel
39 that the modification to ibmtr.c were incorporated into.
40
41 v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
42 Address translation feature of PCMCIA controller is usable so
43 memory windows can be placed in High memory (meaning above
44 0xFFFFF.)

2Linux PCMCIA ethernet adapter driver for the New Media Ethernet LAN.
3 nmclan_cs.c,v 0.16 1995/07/01 06:42:17 rpao Exp rpao
4
5 The Ethernet LAN uses the Advanced Micro Devices (AMD) Am79C940 Media
6 Access Controller for Ethernet (MACE). It is essentially the Am2150
7 PCMCIA Ethernet card contained in the Am2150 Demo Kit.

34 The Linux client driver is based on the 3c589_cs.c client driver by
35 David Hinds.
36
37 The Linux network driver outline is based on the 3c589_cs.c driver,
38 the 8390.c driver, and the example skeleton.c kernel code, which are
39 by Donald Becker.

48Driver Notes and Issues
49-------------------------------------------------------------------------------
50
511. Developed on a Dell 320SLi
52 PCMCIA Card Services 2.6.2
53 Linux dell 1.2.10 #1 Thu Jun 29 20:23:41 PDT 1995 i386
54
552. rc.pcmcia may require loading pcmcia_core with io_speed=300:
56 'insmod pcmcia_core.o io_speed=300'.
57 This will avoid problems with fast systems which causes rx_framecnt
58 to return random values.
59
603. If hot extraction does not work for you, use 'ifconfig eth0 down'
61 before extraction.
62
634. There is a bad slow-down problem in this driver.
64
655. Future: Multicast processing. In the meantime, do _not_ compile your
66 kernel with multicast ip enabled.

3 A PCMCIA ethernet driver for NS8390-based cards
4
5 This driver supports the D-Link DE-650 and Linksys EthernetCard
6 cards, the newer D-Link and Linksys combo cards, Accton EN2212
7 cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
8 mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
9 Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
10 mode. It will also handle the Socket EA card in either mode.

5 This driver supports Megahertz PCMCIA ethernet cards; and
6 Megahertz, Motorola, Ositech, and Psion Dacom ethernet/modem
7 multifunction cards.

12
13 This driver contains code written by Donald Becker
14 (becker@scyld.com), Rowan Hughes (x-csrdh@jcu.edu.au),
15 David Hinds (dahinds@users.sourceforge.net), and Erik Stahlman
16 (erik@vt.edu). Donald wrote the SMC 91c92 code using parts of
17 Erik's SMC 91c94 driver. Rowan wrote a similar driver, and I've
18 incorporated some parts of his driver here. I (Dave) wrote most
19 of the PCMCIA glue code, and the Ositech support code. Kelly
20 Stephens (kstephen@holli.com) added support for the Motorola
21 Mariner, with help from Allen Brost.

2 * Xircom CreditCard Ethernet Adapter IIps driver
3 * Xircom Realport 10/100 (RE-100) driver
4 *
5 * This driver supports various Xircom CreditCard Ethernet adapters
6 * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56,
7 * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100.
8 *
9 * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not
10 * autodetect the media properly. In this case use the
11 * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options
12 * to force the media type.
13 *
