Linux-2.6.12-rc2

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!

+/*  ewrk3.c: A DIGITAL EtherWORKS 3 ethernet driver for Linux.
+
+   Written 1994 by David C. Davies.
+
+   Copyright 1994 Digital Equipment Corporation.
+
+   This software may be used and distributed according to the terms of
+   the GNU General Public License, incorporated herein by reference.
+
+   This driver is written for the Digital Equipment Corporation series
+   of EtherWORKS ethernet cards:
+
+   DE203 Turbo (BNC)
+   DE204 Turbo (TP)
+   DE205 Turbo (TP BNC)
+
+   The driver has been tested on a relatively busy  network using the DE205
+   card and benchmarked with 'ttcp': it transferred 16M  of data at 975kB/s
+   (7.8Mb/s) to a DECstation 5000/200.
+
+   The author may be reached at davies@maniac.ultranet.com.
+
+   =========================================================================
+   This driver has been written  substantially  from scratch, although  its
+   inheritance of style and stack interface from 'depca.c' and in turn from
+   Donald Becker's 'lance.c' should be obvious.
+
+   The  DE203/4/5 boards  all  use a new proprietary   chip in place of the
+   LANCE chip used in prior cards  (DEPCA, DE100, DE200/1/2, DE210, DE422).
+   Use the depca.c driver in the standard distribution  for the LANCE based
+   cards from DIGITAL; this driver will not work with them.
+
+   The DE203/4/5 cards have 2  main modes: shared memory  and I/O only. I/O
+   only makes  all the card accesses through  I/O transactions and  no high
+   (shared)  memory is used. This  mode provides a >48% performance penalty
+   and  is deprecated in this  driver,  although allowed to provide initial
+   setup when hardstrapped.
+
+   The shared memory mode comes in 3 flavours: 2kB, 32kB and 64kB. There is
+   no point in using any mode other than the 2kB  mode - their performances
+   are virtually identical, although the driver has  been tested in the 2kB
+   and 32kB modes. I would suggest you uncomment the line:
+
+   FORCE_2K_MODE;
+
+   to allow the driver to configure the card as a  2kB card at your current
+   base  address, thus leaving more  room to clutter  your  system box with
+   other memory hungry boards.
+
+   As many ISA  and EISA cards  can be supported  under this driver  as you
+   wish, limited primarily  by the available IRQ lines,  rather than by the
+   available I/O addresses  (24 ISA,  16 EISA).   I have  checked different
+   configurations of  multiple  depca cards and  ewrk3 cards  and have  not
+   found a problem yet (provided you have at least depca.c v0.38) ...
+
+   The board IRQ setting   must be at  an unused  IRQ which is  auto-probed
+   using  Donald  Becker's autoprobe  routines.   All  these cards   are at
+   {5,10,11,15}.
+
+   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 included
+   and used  extensively during the  driver development (to save those long
+   reboot sequences). 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 ewrk3.c from the  /linux/drivers/net directory to your favourite
+   temporary directory.
+   2) edit the  source code near  line 1898 to reflect  the I/O address and
+   IRQ you're using.
+   3) compile  ewrk3.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 ewrk3 configuration turned off and reboot.
+   5) insmod ewrk3.o
+   [Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
+   [Adam Kropelin: now accepts irq=x1,x2 io=y1,y2 for multiple cards]
+   6) run the net startup bits for your new 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 ewrk3'.
+
+   Promiscuous   mode has been  turned  off  in this driver,   but  all the
+   multicast  address bits  have been   turned on. This  improved the  send
+   performance on a busy network by about 13%.
+
+   Ioctl's have now been provided (primarily because  I wanted to grab some
+   packet size statistics). They  are patterned after 'plipconfig.c' from a
+   suggestion by Alan Cox.  Using these  ioctls, you can enable promiscuous
+   mode, add/delete multicast  addresses, change the hardware address,  get
+   packet size distribution statistics and muck around with the control and
+   status register. I'll add others if and when the need arises.
