[Bridge] Bridge port states

Hi all,

Can anyone explain me why we need all this per port state information. A 
bridge port seems to be either in BR_STATE_LISTENING, BR_STATE_LEARNING 
or BR_STATE_FORWARDING. I don't get it, thought the bridge is learning 
from MAC addresses of the received packets, therefore while listening. 
Why a bridge port distinquishes these states?

Thanx,
Patrick
