drivers/net: delete Digital EtherWorks-3 support.
This is another one that makes sense to target for obsolescence, since it (a)appeared pre-1995, and (b)was rather rare, and (c)did not really have any statistically significant active linux user base. Removing this ISA 10Mbit driver support is unlikely to be even noticed by the user base of 3.9+ linux kernels, especially when the documentation clearly indicates the vintage with this text: "...designed to work with all kernels > 1.1.33" Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

-The EtherWORKS 3 driver in this distribution is designed to work with all
-kernels > 1.1.33 (approx) and includes tools in the 'ewrk3tools'
-subdirectory to allow set up of the card, similar to the MSDOS
-'NICSETUP.EXE' tools provided on the DOS drivers disk (type 'make' in that
-subdirectory to make the tools).
-
-The supported cards are DE203, DE204 and DE205. All other cards are NOT
-supported - refer to 'depca.c' for running the LANCE based network cards and
-'de4x5.c' for the DIGITAL Semiconductor PCI chip based adapters from
-Digital.
-
-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: Multiple cards now supported by irq=x1,x2 io=y1,y2]
- 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'.
-
-The performance we've achieved so far has been measured through the 'ttcp'
-tool at 975kB/s. This measures the total TCP stack performance which
-includes the card, so don't expect to get much nearer the 1.25MB/s
-theoretical Ethernet rate.
-
-
-Enjoy!

-/* 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.
