An upstream port is a local switch port used to reach a CPU port. DSA still considers a unique CPU port in the whole switch fabric and thus return a unique upstream port for a given switch. This is wrong in a multiple CPU ports environment.
We are now switching to using the dedicated CPU port assigned to each port in order to get rid of the deprecated unique tree CPU port. This patchset makes the dsa_upstream_port() helper take a port argument and goes one step closer complete support for multiple CPU ports.
