Subject: [PATCH net-next 0/3] Make sja1105 treat tag_8021q VLANs more like real DSA tags

This series solves a nuisance with the sja1105 driver, which is that
non-DSA tagged packets sent directly by the DSA master would still exit
the switch just fine.

We also had an issue for packets coming from the outside world with a
crafted DSA tag, the switch would not reject that tag but think it was
valid.

Vladimir Oltean (3):
  net: dsa: sja1105: prevent tag_8021q VLANs from being received on user
    ports
  net: dsa: sja1105: drop untagged packets on the CPU and DSA ports
  net: dsa: tag_sja1105: stop asking the sja1105 driver in
    sja1105_xmit_tpid
