Agree, that is a dumb idea. What's that driver going to do? Use custom
nl80211 extensions?! That way lies insanity.

The only reason for that is to be able to support the wpa_supplicant
modifications used in Android that are not acceptable for upstream
hostap.git (mainly, driver_cmd). This would not add any custom nl80211
extensions; the needed functionality should be added properly to
upstream nl80211.

What's the driver_cmd things they use? If we they add support for
whatever it is to nl80211, why can those not be normal supplicant
interfaces?

If it is fine to remove the custom wpa_supplicant modifications from
Android, this is obviously a moot point, but until that happens, the
easiest approach seems to be to provide a custom driver_*.c based on
nl80211 to isolate the custom changes to user space and to small part of
it at that. I don't really want to see new drivers trying to provide
WEXT support with private ioctls to address need for making it work with
Android..

Indeed -- no way. Seems Android needs to learn upstream.
