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
