You say one thing and revert it right in the next sentence. Ehm now you are confusing me. You state that software rfkill state is not the state as requested by mac80211. Since that is not the case b43 has 2 different methods to indicate the RFKILL state, one is the hardware rfkill state and the second is the software rfkill state. On top of that mac80211 sends configuration commands to b43 to set the radio state. Configuration commands from mac80211 should _not_ trigger rfkill events since they don't represent the RFKILL state but the RADIO state. The RFKILL states as provided by the hardware do trigger rfkill state changes. So apparently in b43 hardware you have 3 settings: * radio enabled/disabled * sw rfkill enabled/disabled * hw rfkill enabled/disabled The latter 2 provide RFKILL state changes when they are changed, but the first one is the state as requested by mac80211 and thus should not generate events.
