-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.
