Apart from Alfred's suggestions to up some sysctl values, I would
suggest - specifically for 3c905* cards - to explicitly configure
the interface media (add 'media 100baseTX' to your ifconfig line).
You did not report any throughput problems, so this might not be
a problem for you; still, it might be worth trying.

G'luck,
Peter
