Mismatch in FT Action Frame

while experimenting with 802.11r functionality of wpa_supplicant/hostapd I
tried roaming between to APs (configured with FT-PSK) using the command
"ft_ds f8:d1:11:15:de:d0" in wpa_cli.
In the hostapd log of one of the APs it says this:
1358436032.545729: hostapd_action_rx: FT_ACTION length 157
1358436032.545736: FT: Received FT Action frame (STA=15:6d:84:6b:f4:f8
Target AP=d1:11:15:de:d0:30 Action=0)
1358436032.545750: FT: Mismatch in FT Action STA address:
1358436032.552326: FT: RRB received packet f8:d1:11:15:de:d0 ->
In my opinion either wpa_supplicant inserts the mac addresses at the wrong
position of the action frame, or hostapd parses the received frame
incorrectly, because you can see a "shift" in the mac adresses' output:
d1:11:15:de:d0:30 should really be f8:d1:11:15:de:d0
15:6d:84:6b:f4:f8 should really be 00:15:6d:84:6b:f4
Can anyone confirm my suspicion?
