Hi Murali
It would be good if you start thinking about all the different
directions. It is not just host to port A and host to port B. What
about port A to Port B? Can it do that in hardware?

I think i need to read more about the switch. I'm starting to wonder
if it has enough intelligence to be usable. Switchdev is about pushing
configuration down into the switch. It does not however sound like
there is that much which is configurable in this switch.
