Farallon Etherwave Nubus cards do work on the Quadra 650.

It turns out that I had set ae0 to 10.1.1.3 instead of 10.1.1.1... then
when I discovered my mistake it somehow associated 10.1.1.1 with
lo0. Coincidently, my the Mac had been set to 10.1.1.3, and that was what
was causing the problems.

At least that's what I think it was, as I got these messages:

Jul 30 23:46:27 moria /netbsd: 08:...:09 on sn0 tried to overwrite arp
info for 10.1.1.3 on lo0
... moria /netbsd: 08:...:09 on ae0 tried to overwrite arp info for
10.1.1.3 on lo0
... moria last message repeated 25 times
... moria last message repeated 24 times
... moria last message repeated 89 times

Where the "..."s are snipped text.

Are my conclusions at least close to right?

BTW: Is there some way to limit the messages that appear when root is
logged on, or it's at the login prompt? The connection messages are
especially annoying.

Thanks for your help,
Daniel
