Subject: [PATCH v3 net-next 00/15] Generic adjustment for flow dissector in DSA

This is the v2 of a series initially submitted in May:

The end goal is to get rid of the unintuitive code for the flow
dissector that currently exists in the taggers. It can all be replaced
by a single, common function.

Some background work needs to be done for that. Especially the ocelot
driver poses some problems, since it has a different tag length between
RX and TX, and I didn't want to make DSA aware of that, since I could
instead make the tag lengths equal.

Changes in v3:
- Added an optimization (08/15) that makes the generic case not need to
  call the .flow_dissect function pointer. Basically .flow_dissect now
  currently only exists for sja1105.
- Moved the .promisc_on_master property to the tagger structure.
- Added the .tail_tag property to the tagger structure.
- Disabled "suppresscc = all" from my .gitconfig.

Vladimir Oltean (15):
  net: mscc: ocelot: move NPI port configuration to DSA
  net: dsa: allow drivers to request promiscuous mode on master
  net: dsa: tag_sja1105: request promiscuous mode for master
  net: dsa: tag_ocelot: use a short prefix on both ingress and egress
  net: dsa: make the .flow_dissect tagger callback return void
  net: dsa: add a generic procedure for the flow dissector
  net: dsa: point out the tail taggers
  net: flow_dissector: avoid indirect call to DSA .flow_dissect for
    generic case
