addPending :: POSIXTime -> IP4 -> ArpTable -> ArpTable Source
Assumption: there is not already a pending ARP query recorded in the ARP table for the given IP address.
lookupArpEntry :: IP4 -> ArpTable -> ArpResult Source
If the ARP table has a fully realized entry for the given IP address, then return it. Otherwise return Pending if we're waiting for this info, or Unknown if nothing is currently known about it.
