SubjectRe: Ethernet NIC dual homing

no, there are examples with too long lines, or
scratched wires where the links stay up, but even arp
doesn't work.

no, simply sending ARP request for a known IP address
which will reply, so generate traffic that can be
counted to tell wether a NIC seems working or not.

I didn't try to set my own IP address though. Perhaps
with arp_filter properly set this could be usefull...

Regards,
Willy
