Implement the required support for extrace the cipher
suite settings from the the RS Information Element and
set the station key based on the 802.11 Station Key
CAPWAP message element.
Group Key update handling is currently not implemented nor is
Station Key update handling.
RFC 5416 copies the order of the capability flags from the
IEEE 802.11 capability IE. However, the bit ordering assumtions
in RFC 5416 differ from IEEE 802.11 (in the RFC the MSB is
numbered 0, in IEEE 802.11 the MSB is numbere 15).
RFC 5416 therefore specifies the capability flags bit reversed
compared to IEEE 802.11.
After the max station inactivity has expired, a probe request
(a data null frame) is sent to the station. It the station does
not ACK this frame, it is removed from the WTP.
Note: inactivity timeout is not the same as the CAPWAP Idle Timeout.
The CAPWAP Idle Timeout would remove a station due to inactivity
even when it is still reachable from the WTP. In contrast, the
inactivity timeout probes whether the station is still present
and only removes it when not.
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.
* add a kernel bash hash list to track station to
radio and wlan id binding
* enforce binding on recv
* configure binding through netlink interface from
WTP process
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
