zxAnZesrPreForwardingTime

During the time between the transit node detecting that its link is
restored and the master node detecting that the ring is restored, 
the secondary port of the master node is still open -- creating the
possibility of a temporary loop in the topology.  To prevent this,
the transit node will place all the protected VLANs transiting the
newly restored port into a temporary blocked state, remember which
port has been temporarily blocked, and transition into the 'pre-
forwarding' state.  When the transit node in the 'pre-forwarding'
state receives a control frame instructing it to flush its bridging
table, it will flush the bridging table, unblock the previously
blocked protected VLANs on the newly restored port, and transition 
to the 'normal' state.
