Re: HEADSUP: arp-v2 has been committed

The flag is not needed. It is only possible to retrieve arp entries by
way of sysctl. The converse of this is you no longer need to grab all
the entries in the routing table and look at each one to determine
which are cloned routes (dynamic host routes) which contain ARP
entries.
