    I do not understand your question, but will try to explain a high-level view of CPSW.

    Port 0 of the 3-port switch is an internal port that connects to the host processor.  Ports 1 and 2 are external ports than can be operated in switch mode or dual MAC mode. 

    In switch mode, any incoming data on ports 1 or 2 will be routed to the host processor or the other external port based on the destination address of the packet.

    In ALE bypass mode the two external ports operate as two independent MACs where incoming packets are always routed to the host processor.  In this mode all packet processing is done by the application code running on the processor.
