			We need to know which channel is used by a running AP and mesh for channel context accounting and finding matching/active interface combination. STA/IBSS have current_bss already which allows us to check which channel a vif is tuned to. Non-fixed channel IBSS can be handled with additional changes. Monitor mode is going to be handled differently. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
