The TI folks had a similar patch that broke open networks, not sure
what was wrong there.
Ultimately, depending on the nl80211 capabilities, the station should
in fact be added (as unauthenticated) before even sending the
authentication response frame, and then stepping through the stages
It should also react to errors by sending a negative association
response I guess.
