| 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! |
