From: Allan Stephens <[EMAIL PROTECTED]>
This fix prevents link flopping and name table inconsistency problems arising
when a node is assigned a different <Z.C.N> value than it used previously.
(Changing the <Z.C.N> value causes other nodes to have two link endpoints
sending to the same MAC address using two different destination <Z.C.N> values,
requiring the receiving node to filter out the unwanted messages.)
