[PATCH net-next v1 0/8] net: dsa: realtek: rtl8365mb: DCB ingress QoS offload

Add DCB-based ingress QoS offload for the RTL8365MB switch via the dcbnl
app interface: a per-port default priority, PCP trust, and DSCP trust.
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.
