12Description:
13 Specifies the duration of the LED blink in milliseconds.
14 Defaults to 50 ms.
15
16 When offloaded is true, the interval value MUST be set to the
17 default value and cannot be changed.
18 Trying to set any value in this specific mode will return
19 an EINVAL error.

25Description:
26 Signal the link state of the named network device.
27
28 If set to 0 (default), the LED's normal state is off.
29
30 If set to 1, the LED's normal state reflects the link state
31 of the named network device.
32 Setting this value also immediately changes the LED state.

38Contact: linux-leds@vger.kernel.org
39Description:
40 Signal transmission of data on the named network device.
41
42 If set to 0 (default), the LED will not blink on transmission.
43
44 If set to 1, the LED will blink for the milliseconds specified
45 in interval to signal transmission.
46
47 When offloaded is true, the blink interval is controlled by
48 hardware and won't reflect the value set in interval.

56
57 If set to 0 (default), the LED will not blink on reception.
58
59 If set to 1, the LED will blink for the milliseconds specified
60 in interval to signal reception.
61
62 When offloaded is true, the blink interval is controlled by
63 hardware and won't reflect the value set in interval.

69Description:
70 Communicate whether the LED trigger modes are offloaded to
71 hardware or whether software fallback is used.
72
73 If 0, the LED is using software fallback to blink.
74
75 If 1, the LED blinking in requested mode is offloaded to
76 hardware.
