mac80211: fix uninitialized variable

2013-10-28T14:05:31+00:00

CSA completion could call in a driver
bss_info_changed() with a garbled `changed` flag
leading to all sorts of problems.

mac80211: process mesh channel switching using beacon

2013-10-28T14:05:30+00:00

Trigger the mesh channel switching procedure if the mesh STA
happens to miss the CSA action frame but able to receive the
beacon containing the CSA and MCSP elements from its peer
mesh STAs.

{nl,cfg,mac}80211: implement mesh channel switch userspace API

2013-10-28T14:05:30+00:00

Implement the required procedures for mesh channel switching as defined
in the IEEE Std 802.11-2012 section 10.9.8.4.3 and also handle the CSA
and MCSP elements as followed:
 * Add the function for updating the beacon and probe response frames
   with CSA and MCSP elements during the period of switching to the new
   channel. Both CSA and MCSP elements must be included in beacon and
   probe response frames until the intended channel switch time.
 * The ifmsh->csa_settings is set to NULL and the CSA and MCSP elements
   will then be removed from the beacon or probe response frames once the
   new channel is switched to.

{nl,cfg,mac}80211: enable the triggering of CSA frame in mesh

2013-10-28T14:05:29+00:00

Allow the triggering of CSA frame using mesh interface. The
rules are more or less same with IBSS, such as not allowed to
change between the band and channel width has to be same from
the previous mode. Also, move the ieee80211_send_action_csa
to a common space so that it can be re-used by mesh interface.

mac80211: process the CSA frame for mesh accordingly

2013-10-28T14:05:28+00:00

Process the CSA frame according to the procedures define in IEEE Std
802.11-2012 section 10.9.8.4.3 as follow:
* The mesh channel switch parameters element (MCSP) must be availabe.
* If the MCSP's TTL is 1, drop the frame but still process the CSA.
* If the MCSP's precedence value is less than or equal to the current
  precedence value, drop the frame and do not process the CSA.
* The CSA frame is forwarded after TTL is decremented by 1 and the
  initiator field is set to 0. Transmit restrict field and others
  are maintained as is.
* No beacon or probe response frame are handled here.

Also, introduce the debug message used for mesh CSA purpose.

mac80211: refactor the parsing of chan switch ie

2013-10-28T14:05:28+00:00

of function parameters.
