Custom wpa_supplicant drivers are not the answer.  The answer is to fix
the driver to work correctly with the WEXT driver.  That's why
NetworkManager _only_ uses the WEXT driver with wpa_supplicant, because
there needs to be standardization on _one_ interface so that we don't
need to re-write stuff 50 times for each driver.

So even if the ralink driver did get into wpa_supplicant, NetworkManager
will not use that custom driver.
