Jouni Malinen 087a1f4efd Suite B: PMKID derivation for AKM 00-0F-AC:11
The new AKM uses a different mechanism of deriving the PMKID based on
KCK instead of PMK. hostapd was already doing this after the KCK had
been derived, but wpa_supplicant functionality needs to be moved from
processing of EAPOL-Key frame 1/4 to 3/4 to have the KCK available.
