Makes sense. I was not using the DSA term, so the "a CPU port" here 
rather meant that the port connects to the CPU. I'll change it to "which 
can be used as a CPU port" on both ports, that should explain that it 
can be used as other than a CPU port, and it does not necessarily 
connect to a CPU MAC.

Thanks.
