Maybe this explains why none of the five Dell Windows 2000
workstations our company recently purchased work correctly with Linux
--- they all work fine, except that they can't seem to receive packets
(except very occasionally).  We concluded that 3Com was manufacturing
junk these days and ditched the cards in favor of Intel cards, which
work fine.

Had the cards reported a different model number, I would have known
they needed updated drivers, but it's too late for that now.  They
looked identical to my working 3c905C cards on older machines in
/proc/pci, and mii-diag didn't help me any.
