From 96c6f337951a03ab40e13a44cf5ea59b14725721 Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Fri, 3 May 2024 15:13:40 +0200 Subject: [PATCH] net: dsa: add support for DCB get/set apptrust configuration Add DCB support to get/set trust configuration for different packet priority information sources. Some switch allow to chose different source of packet priority classification. For example on KSZ switches it is possible to configure VLAN PCP and/or DSCP sources.
