That's a typical setup for people who write network drivers. But Linux
doesn't work properly for that setup, because it returns
arp(ip2) = nic1
arp(ip1) = nic1
when the correct behavior is:
arp(ip2) = nic2
arp(ip1) = nic1
Alan Cox rejected a patch on the grounds that it's a performance issue
and the above setup is not used in production.
