-Subject: [PATCH 12/13] net: dsa: qca8k: implement hw_control ops
-
-Implement hw_control ops to drive Switch LEDs based on hardware events.
-
-Netdev trigger is the declared supported trigger for hw control
-operation and supports the following mode:
-- tx
-- rx
-
-When hw_control_set is called, LEDs are set to follow the requested
-mode.
-Each LEDs will blink at 4Hz by default.
