Subject: [PATCH net-next v2 0/7] net: lan966x: Add support for PCP, DEI, DSCP

This patch series extends lan966x to offload to the hardware the
following features:
- PCP: this configuration is per port both at ingress and egress.
- App trust: which allows to specify a trust order of app selectors.
  This can be PCP or DSCP or DSCP/PCP.
- default priority
- DSCP: this configuration is shared between the ports both at ingress
  and egress.

v1->v2:
- fix whitespace between app_itr and .priority in patch 2
- simplify function lan966x_dcb_ieee_setapp by removing goto and use
  returns instead
- remove check against 0
