+Subject: [PATCH] net: dsa: qca8k: add support for additional modes for netdev
+ trigger
+
+The QCA8K switch supports additional modes that can be handled in
+hardware for the LED netdev trigger.
+
+Add these additional modes to further support the Switch LEDs and
+offload more blink modes.
+
+Add additional modes:
+- link_10
+- link_100
+- link_1000
+- half_duplex
