After you fix that you will potentially find problems with the card's
autonegotiation if you are using a switch. This can be corrected
either by upgrading to Donald's latest driver, upgrading to the latest
devel kernel, or applying this attached patch against the driver in
the 2.2.x kernel. I recommend only going with the patch if you
actually experience the problem, as I wrote it myself and my knowledge
of the tulip driver, tulip chip, and network driver programming is
miniscule compared to the collective efforts that went into the driver
in the first place, so there's a decent chance the patch causes
problems elsewhere (although I haven't had any problems).
