Double Tagging Operation
Step 1
If there is no SPVLAN Tag on received packet, SPVLAN Tag is added.
SPVLAN Tag = TPID : Configured TPID
VID : PVID of input port
Step 2
If a received packet is tagged with CVLAN, the switch transmits it to uplink port changing
to CVLAN. When TPID value of received packet is same with TPID of port, it
recognizes as SPVLAN, and if not as CVLAN.
