The best 100base cards I've used under NetBSD have been
the -old- Netgear cards with the DEC chipset on them.  The=20
latency is way low and throughput is fantastic.  These suckers=20
are hard to find now as all the new NetGear cards have a different=20
chipset on them that doesn't work under NetBSD.  If you have a=20
local dealer that might have some old stock, the boxes=20
have a clear plastic front so you can see the actual card=20
right through the package- look for the "Digital" stamp on the=20
main chip on the NIC itself.

I'm suprised you are having problems with the 3c905 cards.=20
I have a couple 1.4 servers dual-homed with twin 3Com=20
3c905B-TX cards and they work well during their lifespan.  I=20
seem to go through them rather quickly myself,  but they do=20
work well for the period of time that they last.   These are those
real tiny PCI NIC cards- not sure if there might be other 3c905B
cards that 3com makes.

I've got one server that I'm trying the Intel NIC cards on but
that machine seems to lose the network at random times.
I'm not sure if it's the NIC or some other hardware at this
point.
