Maybe what I want to accomplish is not clear. It's like this.
Assuming I have a few SSIDs are forming a bridge, for example,

    wlan0 ( ssid 1 )
    wlan1 ( ssid 2 )
  and so on are bridge into br-lan

If I do tcpdump on br-lan, I would like to be able to identify traffic coming from wlan0 (or wlan1 ) based on the VLAN tag IDs.
Is that possible ?
