I think it's not what you think it is. My understanding is, that this is a special AP mode that allows one to bridge traffic through the AP *AND* the client.

I have not done this, but since nobody else replied I'll explain what I think you have to do: Lets say you have two VLANs, tagged with 5 and 6. 1) create two VAP interfaces with iw: iw phy phy0 interface add vap5 type managed iw phy phy0 interface add vap6 type managed (I think managed is ok, hostapd will change this to ap) 2) run hostapd on each of the VAP interfaces, use different SSIDs 3) create VLAN interfaces on top of your VLAN trunk interface (e.g. where you get the tagged frames). Use either vconfig or ip to do this. vconfig add eth0 5 vconfig add eth0 6 this will create the VLAN interfaces eth0.5 and eth0.6 4) create bridges to connect the AP interfaces with the VLANs brctl addbr "br5" brctl addbr "br6" 5) connect the APs with the corresponding VLANs brctl addif br5 eth0.5 brctl addif br5 vap5 brctl addif br6 eth0.6 brctl addif br6 vap6 Now the *untagged* traffic from VLAN 5 should be bridged to vap5 and from VLAN 6 to vap6. Once again, this is untested! This is just how I think this could be done.
