[PATCH net-next] net: dsa: use dedicated CPU port

From: Vivien Didelot
Date: Wed Sep 20 2017 - 12:31:53 EST


Each port in DSA has its own dedicated CPU port currently available in
its parent switch's ds->ports[port].cpu_dp. Use it instead of getting
the unique tree CPU port, which will be deprecated soon.
