Re: mad mad interrupts(bridging)

As I said I checked the mac addrs on the interfaces, and they are all
different.(maybe the identical mac addrress are myth from the older
cards?). Here is the output of netstat -i.

here is the boot message

also the card shows up as qfe on Solaris, is it normal for it to show up
as hme?

As with the bridging topology, I have another openbsd i386 box setup
exactly the same way without any problem(on a different network). I
upgraded it to dec1 -current as well the other day and it has been working
fine. any other insights?

thanks.

Jake
