====================
net: dsa: mt7530: fix multiple CPU ports, BPDU and LLDP handling

This patch series fixes all non-theoretical issues regarding multiple CPU
ports and the handling of LLDP frames and BPDUs.

I am adding me as a maintainer, I've got some code improvements on the way.
I will keep an eye on this driver and the patches submitted for it in the
future.

v6:
- Change a small portion of the comment in the diff on "net: dsa: mt7530:
  set all CPU ports in MT7531_CPU_PMAP" with Russell's suggestion.
- Change the patch log of "net: dsa: mt7530: fix trapping frames on
  non-MT7621 SoC MT7530 switch" with Vladimir's suggestion.
- Group the code for trapping frames into a common function and call that.
- Add Vladimir and Russell's reviewed-by tags to where they're given.

v5:
- Change the comment in the diff on the first patch with Russell's words.
- Change the patch log of the first patch to state that the patch is just
  preparatory work for change "net: dsa: introduce
  preferred_default_local_cpu_port and use on MT7530" and not a fix to an
  existing problem on the code base.
- Remove the "net: dsa: mt7530: fix trapping frames with multiple CPU ports
  on MT7530" patch. It fixes a theoretical issue, therefore it is net-next
  material.
- Remove unnecessary information from the patch logs. Remove the enum
  renaming change.
- Strengthen the point of the "net: dsa: introduce
  preferred_default_local_cpu_port and use on MT7530" patch.

v4: Make the patch logs and my comments in the code easier to understand.
v3: Fix the from header on the patches. Write a cover letter.
v2: Add patches to fix the handling of LLDP frames and BPDUs.
