PCI lookup issue: 3c905C-TX not found by RTEMS.

[Karel Gardas]

Till,

yes, while looking for a set of supported NICs, I've also found your
excelent jumbo patch against 4.6.2 (your site seems to be the only one
noting RTEMS in conjuction with Etherexpress and 3c90x :-)). I've tested
exactly this code below, but w/o success. My NIC is still not findable...
So for debugging and reporting to rtems-users I've came back to original
code. Anyway, since I'm not 100% sure (just 99% sure) that I've done all
the steps right (i.e recompile rtems, copy *.a, relink server.exe, copy
server.exe), I will give your code a try again in a few minutes.

Thanks,
Karel
