Does this really work correctly in all cases, i.e., is the WPA/RSN IE in
EAPOL-Key message 3/4 correct? I'm especially concerned of cases where
wpa_pairwise != rsn_pairwise. If the driver does not support different
sets of pairwise cipher suites for WPA and RSN/WPA2, only valid
configuration would be to set wpa_pairwise=rsn_pairwise (e.g., leave out
rsn_pairwise).
