Subject: [PATCH net-next v3 0/9] Enhanced DCB and DSCP Support for KSZ Switches

This patch series is aimed at improving support for DCB (Data Center
Bridging) and DSCP (Differentiated Services Code Point) on KSZ switches.

The main goal is to introduce global DSCP and PCP (Priority Code Point)
mapping support, addressing the limitation of KSZ switches not having
per-port DSCP priority mapping. This involves extending the DSA
framework with new callbacks for managing trust settings for global DSCP
and PCP maps. Additionally, we introduce IEEE 802.1q helpers for default
configurations, benefiting other drivers too.

Change logs are in separate patches.

Oleksij Rempel (9):
  net: dsa: add support for DCB get/set apptrust configuration
  net: dsa: microchip: add IPV information support
  net: add IEEE 802.1q specific helpers
  net: dsa: microchip: add multi queue support for KSZ88X3 variants
  net: dsa: microchip: add support for different DCB app configurations
  net: dsa: microchip: dcb: add special handling for KSZ88X3 family
  net: dsa: microchip: enable ETS support for KSZ989X variants
  net: dsa: microchip: init predictable IPV to queue mapping for all non
    KSZ8xxx variants
  net: dsa: microchip: let DCB code do PCP and DSCP policy configuration
