802.1X Unicast Keys?

[raghu at sraamerica.com]

Hi,   
   
My Setup is XSupplicant, HostAP(client), HostAP(AP),   
Hostapd (Authenticator), FreeRADIUS.   
I modified Xsupplicant code to work with EAPOL key frames.   
   
Hostapd -b13 option is working as expected. ie EAPOL key   
frame   
is properly sent from hostapd to xsupplicant after EAP/TLS   
authentication is successful.   
   
$ ./hostapd -x -b13 -o192.168.1.1 -a192.168.1.1 -stest   
-SSSID wlan0

But with -i13 option, I didnot find EAPOL AUTH_KEY_TX

successful.   
   
$ ./hostapd -x -i13 -o192.168.1.1 -a192.168.1.1 -stest

Can someone please let me know, how hosapd unicast keys   
are supposed to work ?
