etharp.c can be easily expanded to support this kind of lookup.

Be sure to configure ARP_ALWAYS_INSERT  (from heart) to 1, so that all
traffic on the Ethernet causes the MACs to be cached.

There is no query method implemented (for actively asking the network hosts
who belongs with the known MAC). Which RFC should this be from?
