check_mac( $device, $node, $port_macs? )
Given a Device database object and a MAC address, perform various sanity checks which need to be done before writing an ARP/Neighbor entry to the database storage.
Returns false, and might log a debug level message, if the checks fail.
Returns a true value if these checks pass:
MAC address is well-formed (according to common formats)
MAC address is not all-zero, broadcast, CLIP, VRRP or HSRP
Optionally pass a cached set of Device port MAC addresses as the third argument, in which case an additional check is added:
MAC address does not belong to an interface on any known Device
