	We are only getting 35mbits using ttcp.

the best i've seen on our unswitched 100base-tx hub was ~7.5MB/s, i think that's when
the acks collide with the data.

i'm hoping to get a switch in a few weeks and i can try some tests with mixes of
cards, there's certainly more tuning to be done.

i added a new card to the list today, the adaptec (cogent) ana-6910fx. it uses the
digital 21140 chip.
