   The Pro/100B actually performs better in some benchmarks for raw speed, and
the overhead of the fxp driver is significantly lower (10-20%). On the other
hand, old Pro/100B's have a bug in the NIC that causes them to lock up when
they get garbage, and I haven't implemented (yet?) a work-around for this. In
any case, both the DEC-chip based and Intel-chip based cards work well with
FreeBSD and the current drivers for both have no known bugs.
