The EtherWORKS 3 driver in this distribution is designed to work with all
|
| 2 |
|
|
kernels > 1.1.33 (approx) and includes tools in the 'ewrk3tools'
|
| 3 |
|
|
subdirectory to allow set up of the card, similar to the MSDOS
|
| 4 |
|
|
'NICSETUP.EXE' tools provided on the DOS drivers disk (type 'make' in that
|
| 5 |
|
|
subdirectory to make the tools).
|
| 6 |
|
|
|

|
|
The supported cards are DE203, DE204 and DE205. All other cards are NOT
|
| 8 |
|
|
supported - refer to 'depca.c' for running the LANCE based network cards and
|
| 9 |
|
|
'de4x5.c' for the DIGITAL Semiconductor PCI chip based adapters from
|
| 10 |
|
|
Digital.

The ability to load this driver as a loadable module has been included and
|
| 13 |
|
|
used extensively during the driver development (to save those long reboot
|
| 14 |
|
|
sequences). To utilise this ability, you have to do 8 things:
|
| 15 |
|
|
|
| 16 |
|
|
0) have a copy of the loadable modules code installed on your system.
|
| 17 |
|
|
1) copy ewrk3.c from the /linux/drivers/net directory to your favourite
|
| 18 |
|
|
temporary directory.
|
| 19 |
|
|
2) edit the source code near line 1898 to reflect the I/O address and
|
| 20 |
|
|
IRQ you're using.
|
| 21 |
|
|
3) compile ewrk3.c, but include -DMODULE in the command line to ensure
|
| 22 |
|
|
that the correct bits are compiled (see end of source code).
|
| 23 |
|
|
4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
|
| 24 |
|
|
kernel with the ewrk3 configuration turned off and reboot.
|
| 25 |
|
|
5) insmod ewrk3.o
|
| 26 |
|
|
[Alan Cox: Changed this so you can insmod ewrk3.o irq=x io=y]
|
| 27 |
|
|
6) run the net startup bits for your new eth?? interface manually
|
| 28 |
|
|
(usually /etc/rc.inet[12] at boot time).
|
| 29 |
|
|
7) enjoy!
|
| 30 |
|
|
|
| 31 |
|
|
Note that autoprobing is not allowed in loadable modules - the system is
|
| 32 |
|
|
already up and running and you're messing with interrupts.
|
| 33 |
|
|
|
| 34 |
|
|
To unload a module, turn off the associated interface
|
| 35 |
|
|
'ifconfig eth?? down' then 'rmmod ewrk3'.
|
| 36 |
|
|
|
| 37 |
|
|
The performance we've achieved so far has been measured through the 'ttcp'
|
| 38 |
|
|
tool at 975kB/s. This measures the total tcp stack performance which
|
| 39 |
|
|
includes the card, so don't expect to get much nearer the 1.25MB/s
|
| 40 |
|
|
theoretical ethernet rate.
|

|
|

|
|
Enjoy!
