In the majority of cases a port_update notification pertains a change in the properties affecting port filter, and does not affect port wiring, ie: the local vlan tag. This patch simply avoids doing port wiring/unwiring if the local vlan tag did not change. The extra overhead for the ovs-db get operation is offset by the fact that get commands are generally faster than set commands, and by avoiding executing the ovs-ofctl operation.
