etharp_query() sends one etharp_request() per output packet if the address's
entry is pending. This means that a sudden burst of packets can lead to a
broadcast storm, which we might want to prevent.

Also, RFC 826 (ARP) and RFC 1122 (requirements for internet hosts) might have
something to say on this...
