SubjectRe: natsemi.c failure in 2.4.6
Hi,

Okay, I ripped mii-diag out of the bootup scripts.

I just checked, it looks like a switch. Sorry for the confusion, but it was
advertised as a hub when I bought it, so I didn't check to see which it was.
(Until now).

Yup, it was forced to 10baseT-HD during bootup. It didn't work and a few
tcpdumps later, I changed it to 100baseTx-FD via mii-diag to see if it would
make a difference. That's when I got the mii-diag output I put in my mail.

I just booted with it disabled and tried it, but I'm still getting the same
symptoms, though the first time I tried to ping, I got *one* reply from the
NetBSD box.

Anything else I can do to help?
