Offloading of inter-VLAN routing. There's also some multicast and qos 
capability too.

I gather the general idea is to provide mechanisms for the hardware to 
accelerate parts of the forwarding plane. I haven't got into the details 
of that yet, my first set of requirements is just around basic L2 
switching which I think is pretty well supported at this point.
