I don't remember seeing one.

The APs run on two computers conected via LAN, bridging of the APs is configured. When the STA is conected to one of the APs it also can talk to the computer running the other AP, so the "backbone" works. BTW: The same happens using virtual WLAN (mac80211hwsim).

Which hostapd version are you using? Please note that there were couple
of important fixes to 802.11r in February related to how the management
frames (RRB) are sent between the APs when using bridging. Those changes
are not included in any release yet, so I would recommend re-testing
with the current snapshot from hostap.git (0.8.x).
