even without 802.11r when devices are roaming within the same SSID, some 
don't refresh DHCP after changing the BSSID. I believe a recent version 
of MAC OS was doing so and maybe others, though I'm not sure which HW/SW 
exactly was used on client side. So that is why I built DHCP-Snooping / 
IP+ARP-Filter on my APs in a way that those stations don't loose network
