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 :)
