If the fxp driver seems to be "slow as hell", I'd suggest there's
something else which is wrong with your system. As far as I know, the
NetBSD fxp driver is basically the same as the FreeBSD fxp driver,
written by David Greenman. On FreeBSD, the Intel Pro 100B (and the
newer 100+ with integrated PHY) with the fxp driver is just about
*the* fastest and most efficient 100 Mbps card/driver available. As
an example, with this card a P-133 can *receive* a full 100 Mbps, and
can *almost* send a full 100 Mbps (both measured with ttcp and NetPerf).
