A little weird, eh? :-) CP assigns a virtual MAC to all NICs, even virtual Hipersockets, but it doesn't get used for anything, except to make apps that insist on MACs happy. I think Linux may only do this if fake_ll=yes is specified; I don't remember for sure. On a real Hipersocket, the MAC address is not shown since the h/w doesn't support it. In either case, traffic is directed by IP address, not MAC, and no ARP is performed.
