Instead of haing a pool of unsused BSS Id's and a list of active
BSS's (wlans), use a single array and only mark the BSS Id as used
or unused.
When leaving RUN state, release (stop) all used BSS.
Add suport to enable 80211n support on the BSS and set
station parameters through the "Add Station" procedure.
Setting 802.11n radio parameters is rudementary and does
not work yet.
The director has the opportunity to change the configuration of AC in join
connection. The virtual interfaces which encapsulate the wifi stations is
managed dynamically by the Director.
The AC must request authorization from Director for associate a station.
Complete the IEEE802.11 Station Association with interation of AC in LocalMAC mode.
After the IEEE802.11 Authorization / Association is complete, the AC can now
authorize the WTP to accept data station packets with Station Configuration Message.
The virtual interfaces are created at the startup of the wtp to reduce the time
required to configure a wireless interface.
Applied some patches to build the WTP on OpenWRT trunk
