Actually I'm curious about this behaviour...if we have another IBSS with
ESSID=x and BSSID=y1 and we start a new IBSS with ESSID=x (the same) and a fixed
BSSID=y2 then the two cells will not join each other...
At this point, what is another new client supposed to do (if it has not fixed
BSSID)? join the first one? the second one? this maybe an already mentioned and
solved problem but actually this is not totally clear to me...does the ieee standard 
'allow' such scenario?
