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 allow 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. Any further comments are welcomed.
