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. 20 21 What: /sys/class/leds/<led>/link 22 Date: Dec 2017 23 KernelVersion: 4.16 24 Contact: linux-leds@vger.kernel.org 25 Description: 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. 33 34 35 What: /sys/class/leds/<led>/tx 36 Date: Dec 2017 37 KernelVersion: 4.16 38 Contact: linux-leds@vger.kernel.org 39 Description: 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. 49 50 What: /sys/class/leds/<led>/rx 51 Date: Dec 2017 52 KernelVersion: 4.16 53 Contact: linux-leds@vger.kernel.org 54 Description: 55 Signal reception of data on the named network device. 56 57 If set to 0 (default), the LED will not blink on reception. 58 59 If set to 1, the
