====================
NXP SJA1105 VLAN regressions

These are 3 patches to fix issues seen with some more varied testing
done after the changes in the "Traffic termination for sja1105 ports
under VLAN-aware bridge" series were made:
https://patchwork.kernel.org/project/netdevbpf/cover/20210726165536.1338471-1-vladimir.oltean@nxp.com/

Issue 1: traffic no longer works on a port after leaving a VLAN-aware bridge
Issue 2: untagged traffic not dropped if pvid is absent from a VLAN-aware port
Issue 3: PTP and STP broken on ports under a VLAN-aware bridge
