Really?  OK, I may have to test that again.  But why doesn't that
happen automatically?  On another host I run an agr0 interface over a
wm0/wm1 combination, and I don't have to tweak anything manually wrt.
MAC addresses to make that work.

I should perhaps mention that I've been testing agr with bnx on
netbsd-6 code.
