I didn't mean to say exactly this, the second phrase was an addition
through which I tried to make it clear that the "cpu" label *is* used,
but only by the drivers using platform data. With OF it's not, neither
that nor label = "dsa". We have other means of recognizing a CPU or DSA
port, by the 'ethernet' and/or 'dsa' phandles.

Additionally, the label is optional even for user port. One can have
udev rules that assign names to Ethernet ports. I think that is even
encouraged; some of the things in DSA predate the establishment of some
best practices.
