The iwpriv call specifies whether WPA1 or WPA2 is enabled. That was really
meant for configuring the authenticator but I overloaded it's use for station
driver_madwifi.c blindly enables WPA1 so the RSN (WPA2) message elements are
discarded. The proper fix is to permit either WPA1 or WPA2 use. This
requires a minor change to the net80211 layer. Until then using iwpriv to
toggle state after scanning is started is a workaround.
I sent Wilfried a patch to test. Once he gets back to me the attached change
to driver_madwifi.c should fix things in wpa_supplicant.
