br0

--------------------------------------------

eth0 eth1 eth2

Machine A machine B
suppose there is a UDP bidirectional traffic between machine A and B.
Then there will be bridge port
info in "brctl showmacs br0" command output. After some time, UDP
traffic becomes only uni directional( say
only from machine A to B , there is no traffic from B to A ). Then
before bridge ages out , B got removed ; but link eth2
is not going down ( no link down message at eth2, it can be achieved
if eth2 to a harware switch , and machine
was connected to one port of that switch ). Then traffic will flood or
will black hole till ageing timer expire.
As from code , i can see that br_handle_frame_finish() will call
br_forward() as there is an fdb entry. right ? so traffic will black
hole ?!!
