That is exactly what ft_bridge is designed for, so it will certainly
need extra patches. The most recent version was posted as "[PATCH 00/44]
Improvements for roaming" (2016-02-24) on the hostapd mailing list.

I've seen stations that do and that do not perform an DHCP REQUEST after
roaming, so I think that might require extra steps like extra per-sta
routes or getting the station to change its ip. Hostapd will currently
not exchange (push/pull response) an sta ip address information during
802.11r roaming.
