+    Fix fallback from failed PMKSA caching into full EAP authentication
+    
+    Commit 83935317a78fb4157eb6e5134527b9311dbf7b8c added forced
+    disconnection in case of 4-way handshake failures. However, it should
+    not have changed the case where the supplicant is requesting fallback
+    to full EAP authentication if the PMKID in EAPOL-Key message 1/4 is
+    not know. This case needs to send an EAPOL-Start frame instead of
+    EAPOL-Key message 2/4.
+    
+    This works around a problem with APs that try to force PMKSA caching
+    even when the client does not include PMKID in (re)association request
+    frame to request it. [Bug 355]
