Oleksij Rempel says:
====================
add 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.
Compared to v6 this series includes some new patches for DSCP global
mapping support and QoS selftest script for KSZ9477 switches.
