I believe that when the new station is added (NEW_STA event), it will
simply send out a 1/4 EAPOL frame. Since both do that, I guess it does
some kind of de-duplication? Whoever sends it first wins or something,
but I don't really know. Maybe we should take the discussion to the
hostap list at this point :-)
