Subject: [PATCH v2 net-next 0/8] 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.

Vladimir Oltean (8):
  net: dsa: felix: program host FDB entries towards PGID_CPU for
    tag_8021q too
  net: dsa: felix: bring the NPI port indirection for host MDBs to
    surface
  net: dsa: felix: bring the NPI port indirection for host flooding to
    surface
  net: dsa: introduce the dsa_cpu_ports() helper
  net: dsa: felix: manage host flooding using a specific driver callback
  net: dsa: remove port argument from ->change_tag_protocol()
  net: dsa: felix: dynamically determine tag_8021q CPU port for traps
  net: dsa: felix: reimplement tagging protocol change with function
    pointers
