[PATCH 2/8 v3] cfg80211: emulate connect with auth/assoc

Johannes Berg
2009-06-30T11:53:55Z

This adds code to cfg80211 so that drivers (mac80211 right
now) that don't implement connect but rather auth/assoc can
still be used with the nl80211 connect command. This will
also be necessary for the wext compat code.
