This patch is based on the original work by Boris Presman and Victor Goldenshtein. Channel Switch Announcement support has been removed and event handling as well as channel set handling was changed, among various other changes.

|
|

|
|
* reporting with wpa_supplicant_event() and some convenience helper functions
