It takes way longer than that when it doesn't work at all.
Maybe toggle between the two modes if user space does not provide guidance (try fast way first, then slow if
fast didn't find anything), and have the supplicant send down explicit request for each behaviour so that in the
driver you know if supplicant is up to date or not?
