Merge branch 'dsa-changes-for-multiple-cpu-ports-part-1'
Vladimir Oltean says:
====================
DSA changes for multiple CPU ports (part 1)
I am trying to enable the second internal port pair from the NXP LS1028A
Felix switch for DSA-tagged traffic via "ocelot-8021q". This series
represents part 1 (of an unknown number) of that effort.
It does some preparation work, like managing host flooding in DSA via a
dedicated method, and removing the CPU port as argument from the tagging
protocol change procedure.
In terms of driver-specific changes, it reworks the 2 tag protocol
implementations in the Felix driver to have a structured data format.
It enables host flooding towards all tag_8021q CPU ports. It dynamically
updates the tag_8021q CPU port used for traps. It also fixes a bug
introduced by a previous refactoring/oversimplification commit in
net-next.
