In this version of switch driver, we split the dma channels for the switch.
2 for port0 and 2 for port1. So that we can do internal bridging if necessary.
In switch mode, packets coming in from port0 or port1 is able to do Destination
address lookup. Packets coming from port0 with destination address of port1 should
not go to pmac again. The switch hardware should be able to do the switch in the hard
ware level. Packets coming from the pmac should not do the DA look up in that the
desination is already known for the kernel. It only needs to go to the correct NIC to
find its way out.
