This seems like a worthy enhancement. Not necessarily, we have a event based facility for that, the functions are empty though because the consumer, wpa_supplicant, is not able to make any use of it. There were some changes in 0.7 for interface states but I'm not sure what exactly changed, it might be possible to use events for the 'rfkill on' case, the 'rfkill off' might still need polling.. Once Rui has imported the new wpa stuff, someone should implemented the proper calls :) -- Bernhard
