From 286efd34d1a1ef5d83f9441b5e59421a26738169 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Thu, 30 Apr 2026 10:47:38 +0200 Subject: [PATCH] net: airoha: configure QoS channel for HW accelerated flowtable traffic As done for the SW path, configure the QoS channel for HW accelerated traffic according to the user port index when forwarding to a DSA port, or rely on the GDM port identifier otherwise. This allows HTB shaping to be applied to HW accelerated traffic.
