The goal of the current implementation was to get minimal implementation
to pass mandatory certification requirements with a driver (not
nl80211-based). In other words, wpa_supplicant was accepting any request
if NoA was not used at the GO and rejecting any request if NoA was used.
As pointed out in this thread, more complete support needs quite a bit
more work and needs to include with architecture design for NoA
management in general.
In other words, I cannot apply this patch, but I would be fine with a
small patch to make this minimal design "work" with nl80211, i.e., make
sure we do not accept any request incorrectly if the device happens to
be using NoA internally without letting mac80211/wpa_supplicant know.
