1 | 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 | ||
7 | 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. | |
11 | ||
12 | 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 | [Adam Kropelin: Multiple cards now supported by irq=x1,x2 io=y1,y2] | |
28 | 6) run the net startup bits for your new eth?? interface manually | |
29 | (usually /etc/rc.inet[12] at boot time). | |
30 | 7) enjoy! | |
31 | ||
32 | Note that autoprobing is not allowed in loadable modules - the system is | |
33 | already up and running and you're messing with interrupts. | |
34 | ||
35 | To unload a module, turn off the associated interface | |
36 | 'ifconfig eth?? down' then 'rmmod ewrk3'. | |
37 | ||
38 | The performance we've achieved so far has been measured through the 'ttcp' | |
39 | tool at 975kB/s. This measures the total TCP stack performance which | |
40 | includes the card, so don't expect to get much nearer the 1.25MB/s | |
41 | theoretical Ethernet rate. | |
42 | ||
43 | ||
44 | Enjoy! | |
