Is this running with a GENERIC kernel or did you build one specially? What
do
you mean by "almost"? :)

I wasn't expecting much, but I was hoping it could at least get the link up
and
send some packets.. I don't need it to run flat out

fpa(4) is good if you wane play FDDI or if you have old machines with

Well, when I said "network core" I meant "my personal not-for-profit networ=
k
core".
If I could afford to run gigabit fiber all over the place, I wouldn't be
using NetBSD on
a bunch of old Ultra 10s!

I see that Linux "supports" this card as well with what is apparently a
slightly different
driver. I'm going to give it a shot with debian sarge when i get back home
today and see
if it has any better luck at running the DEFPA. If it works, I'll probably
just use Linux.

If that works any better, I plan to try and juxtapose the NetBSD and Linux
fpa drivers and
see if I can combine them somehow to get something working in NetBSD -- I'd
much rather
use NetBSD than Linux, ugh. I'm not promising anything -- I'm no programmer
-- but I *did*
waste, and am in fact still wasting, over five years of my life in
electrical engineering school,
so I should be able to figure something out -- right? right. :)

So I hope.
