APs with the same SSID build up an ESSID which has to be one big L2 
broadcast domain. A STA which roams from one BSSID to another in the 
same ESSID don't need to do a DHCP request - this would break roaming 
(doing another DHCP request takes much time and if the STA get's an 
different IP in the new BSSID it would break any L3 connections).

Thomas
