These are the patches required to support Mesh Basic Service Set (MBSS)
channel switch.
The design is more or less same with the IBSS. Additional procedures
or elements that are required for mesh operation are as follow:
* Add additional information element (IE) known as Mesh Channel Switch
Parameters (MCSP) required in CSA action, beacon and probe response
frames.
* Forwarding of CSA frame if the conditions defined in the standard
are met.
Limitations:
* Channel switch is only allowed for the same band and also same channel
width from the previous setting.
These patches are reviewed and commented by Bob Copeland, Thomas Pedersen
and Johannes Berg. Jean-Pierre has also commented on typos error. Any
further comments are welcomed.
These patches also include refactoring the ieee80211_parse_ch_switch_ie to
reduce the number of function parameters.
Testing:
The patches are tested using ath9k.
