Add WPA-None support:
* WPA-None requires ap_scan=2: The major difference between ap_scan=1 (default) and 2 is, that no IEEE80211_IOC_SCAN* ioctls/functions are called, though, there is a dependency on those. For example the call to wpa_driver_bsd_scan() sets the interface UP, this never happens, therefore the interface must be marked up in wpa_driver_bsd_associate(). IEEE80211_IOC_SSID also is not called, which means that the SSID has not been set prior to the IEEE80211_MLME_ASSOC call. * WPA-None has no support for sequence number updates, it doesn't make sense to check for replay violations.. * I had some crashes right after the switch to RUN state, issue is that sc->sc_lastrs was not yet defined. Approved by: rpaulo (mentor) MFC after: 3 weeks
