In the upstream direction, WGB removes the 802.1q header from the packet while sending to the WLC. 
In the downstream direction while forwarding the packet to the switch connecting the wired-client, the 
WLC sends the packet to WGB without the 802.1q tag and WGB adds a 4-byte 802.1q header based on 
the destination mac-address. (For detailed information on VLANs, refer to
