sending from primary node, the ring has been restored, at the same time the primary
node block its secondary port, and sends its neighbor LINK-UP-Flush-FDB packet.
After MRPP ring port refresh UP on transfer node, the primary node maybe find ring
restore after a while. For the normal data VLAN, the network maybe forms a temporary
ring and creates broadcast storm. To avoid temporary ring, transfer node finds it to
connect to ring network port to refresh UP, immediately block temporarily (only permit
control VLAN packet pass), after only receiving LINK-UP-FLUSH-FDB packet from
primary node, and releases the port block state.
