Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

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.
