Add a new rc.d script, static_arp, which enables the administrator to
statically bind IPv4 <-> MAC address at boot time. In order to use this, the administrator needs to configure the following rc.conf(5) variable: - static_arp_pairs: A list of names for static bind pairs, and, - a series of static_arp_(name): the arguments that is being passed to ``arp -S'' operation. Example: static_arp_pairs="gw" static_arp_gw="192.168.1.1 00:01:02:03:04:05" See the rc.conf(5) manual page for more details. Reviewed by: -rc@ MFC after: 2 weeks
