What:		/sys/class/leds/<led>/device_name
Date:		Dec 2017
KernelVersion:	4.16
Contact:	linux-leds@vger.kernel.org
Description:
		Specifies the network device name to monitor.

What:		/sys/class/leds/<led>/interval
Date:		Dec 2017
KernelVersion:	4.16
Contact:	linux-leds@vger.kernel.org
Description:
		Specifies the duration of the LED blink in milliseconds.
		Defaults to 50 ms.

		With hw_control ON, the interval value MUST be set to the
		default value and cannot be changed.
		Trying to set any value in this specific mode will return
		an EINVAL error.

What:		/sys/class/leds/<led>/link
Date:		Dec 2017
KernelVersion:	4.16
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link state of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link state
		of the named network device.
		Setting this value also immediately changes the LED state.


What:		/sys/class/leds/<led>/tx
Date:		Dec 2017
KernelVersion:	4.16
Contact:	linux-leds@vger.kernel.org
Description:
		Signal transmission of data on the named network device.

		If set to 0 (default), the LED will not blink on transmission.

		If set to 1, the LED will blink for the milliseconds specified
		in interval to signal transmission.

		With hw_control ON, the blink interval is controlled by hardware
		and won't reflect the value set in interval.

What:		/sys/class/leds/<led>/rx
Date:		Dec 2017
KernelVersion:	4.16
Contact:	linux-leds@vger.kernel.org
Description:
		Signal reception of data on the named network device.

		If set to 0 (default), the LED will not blink on reception.

		If set to 1, the LED will blink for the milliseconds specified
		in interval to signal reception.

		With hw_control ON, the blink interval is controlled by hardware
		and won't reflect the value set in interval.

What:		/sys/class/leds/<led>/hw_control
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Communicate whether the LED trigger modes are driven by hardware
		or software fallback is used.

		If 0, the LED is using software fallback to blink.

		If 1, the LED is using hardware control to blink and signal the
		requested modes.

What:		/sys/class/leds/<led>/link_10
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link speed state of 10Mbps of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link state
		speed of 10MBps of the named network device.
		Setting this value also immediately changes the LED state.

What:		/sys/class/leds/<led>/link_100
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link speed state of 100Mbps of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link state
		speed of 100Mbps of the named network device.
		Setting this value also immediately changes the LED state.

What:		/sys/class/leds/<led>/link_1000
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link speed state of 1000Mbps of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link state
		speed of 1000Mbps of the named network device.
		Setting this value also immediately changes the LED state.

What:		/sys/class/leds/<led>/half_duplex
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link half duplex state of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link half
		duplex state of the named network device.
		Setting this value also immediately changes the LED state.

What:		/sys/class/leds/<led>/full_duplex
Date:		Jun 2023
KernelVersion:	6.5
Contact:	linux-leds@vger.kernel.org
Description:
		Signal the link full duplex state of the named network device.

		If set to 0 (default), the LED's normal state is off.

		If set to 1, the LED's normal state reflects the link full
		duplex state of the named network device.
		Setting this value also immediately changes the LED state.
