or be "on" based on

+
+ The current supported offload triggers are:
+ - blink_tx: Blink LED on tx packet receive
+ - blink_rx: Blink LED on rx packet receive
+ - keep_link_10m: Keep LED on with 10m link speed
+ - keep_link_100m: Keep LED on with 100m link speed
+ - keep_link_1000m: Keep LED on with 1000m link speed
+ - keep_half_duplex: Keep LED on with half duplex link
+ - keep_full_duplex: Keep LED on with full duplex link
+ - option_linkup_over: Blink rules are ignored with absent link
+ - option_power_on_reset: Power ON Led on Switch/PHY reset
+ - option_blink_2hz: Set blink speed at 2hz for every blink event
+ - option_blink_4hz: Set blink speed at 4hz for every blink event
+ - option_blink_8hz: Set blink speed at 8hz for every blink event
+
+ These blink modes are present in the LED sysfs dir under
+ hardware-phy-activity if supported by the LED driver.
+
+ This trigger can be used only by LEDs that support Hardware mode.
