Fig 8 State after REUP sends MAC address updating packet
To support up-stream devices which don't support MAC address updating message,
when Gi0/2 changes to forwarding state, Switch D will send MAC address updating
packet on behalf of user PC, so that Switch A can update the MAC address of user PC
to Gi0/4, thus recovering downlink data transmission on Switch A.
