Once the gateway support is merged I'd like to implement some ARP table improvements.

The main thing I would like:

Actual table with 16 elements. Use simple hash to determine index (xor of all nibbles maybe?)
Add crossbar to arp table. Allow IP rx to write entries. In a lot of scenarios a UDP component will only reply to incoming packets. This means it will remove the need for ARP queries in this scenario at all. It will also allow DHCP to query ARP entries in the future.
