Operstate management

Hi all,

I have a problem with the Mac80211 driver and Wpa_supplicant in
operstate management.

My sta is connected to AP1 and I launch iperf from the sta to a computer
(behind the AP).
I force a handover from AP1 to AP2 and the sta sends an arp packed
during the WPA Handshake.

The tcpdump capture is given below:
17:43:12.964096 EAPOL key (3) v2, len 95
17:43:12.998439 EAPOL key (3) v1, len 117

I checked the wireless interface state during WPA Handshake, the
Operstate during WPA Handshake is set to IF_OPER_DORMANT.

Is it normal that the local IP stack sends a frame with this operstate ?
If I've correctly understood this state, the Local IP stack should wait
the IF_OPER_UP to transfert data. Is it right?

What is the link between the operstate and link_mode?

Any help will be appreciatted.
