Traffic for which there is no forwarding entry. For example, an ip
that has no arp entry for the directly connected interface. Router
then needs to arp to associate mac-ip. This is triggered by a glean
adjacency covering the directly connected network.

("glean" didn't mean much to me until we inadvertently interrupted
this normal process with a slightly too restrictive CoPP. Those kind
of lessons tend to stick with you...)
