do_arpnip( $device, $snmp )

Given a Device database object, and a working SNMP connection, connect to a device and discover its ARP cache for IPv4 and Neighbor cache for IPv6.

Will also discover subnets in use on the device and update the Subnets table.

store_arp( $mac, $ip, $name, $now? )

Stores a new entry to the node_ip table with the given MAC, IP (v4 or v6) and DNS host name.

Will mark old entries for this IP as no longer active.

Optionally a literal string can be passed in the fourth argument for the time_last timestamp, otherwise the current timestamp (now()) is used.
