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.
