   A couple of questions: Which version of FreeBSD is running on those
machines? Are you sure that the cards are Pro/100+'s and not Pro/100B's?
They look very similar, except the 100B has an extra chip. Are you using
the cards in 10Mbps mode or 100Mbps mode? Are they connected to a hub or
a switch?
