He never proved conclusively that it wasn't a hardware issue...  We
were basicly using the same driver, and he apparently was able to send
the packet that I was unable to, but I don't remeber him providing
logs that the packet matched exactly what I was sending... (ethernet
mac and all)...

The ethernet issue is that apparently the MAC hits both an underrun
(on an 80 byte packet while 1500 byte nfs writes clear fine) and a
loss of CRS durning the preamble...

It's likely that there is some special non-ethernet MAC setting that
could be messing things up that NetBSD sets much earlier in boot, and
we aren't setting, but tracking down what that setting is won't be
easy...

He forgot to mention that his research was after a year and a half of
ignoring my requests for support before that...

I'm willing to help someone, but short of having the vendor(s) be truely
insterested in solving the ethernet issue, I'd be careful...  I did
have a request in to Cirrus a long time ago, but I can't seem to log
in to see the status..
