Changeset 51138 in vbox for trunk/src/VBox/Devices/Network

Message:

NAT: slirp_arp_cache_update: ARP maps IP to MAC, so check for IP match
and update the MAC, not the other way around. This makes it possible
to use proxy ARP in the guest - otherwise different IPs take turns
kicking each other out of the single entry for the guest MAC.
