[ale] arp port

[Shawn Zabel]

The destination host receives the request and replies with it's own hardware
address. The source host then uses the hardware address of the destination
host to send packets. If the destination host is on another subnet, the
hardware address of the local router will be used (proxy ARP). Bridges and
switches do not proxy ARP.
