It also adds the few net/core ieee8021q helpers the driver needs. Nothing changes on the wire until an admin enables PCP or DSCP trust; until then every frame takes the port default and lands on one queue. Tested on an RTL8365MB-VC. ETS scheduling and CPU-tag ingress pre-classification build on this and will follow once it lands.
