Hi Kapil,

This is what patch ports are for. They are only traversed for the first packet 
of a flow in the slow path. The resulting datapath flow entry collapses the 
processing in both bridges into a single megaflow. So there is no performance 
overhead compared to having a single bridge.

Regards, Jan
