53 Contact: linux-leds@vger.kernel.org
55 Signal reception of data on the named network device.
57 If set to 0 (default), the LED will not blink on reception.
59 If set to 1, the LED will blink for the milliseconds specified
60 in interval to signal reception.
62 When offloaded is true, the blink interval is controlled by
63 hardware and won't reflect the value set in interval.
65 What: /sys/class/leds/<led>/offloaded
68 Contact: linux-leds@vger.kernel.org
70 Communicate whether the LED trigger modes are offloaded to
71 hardware or whether software fallback is used.
73 If 0, the LED is using software fallback to blink.
75 If 1, the LED blinking in requested mode is offloaded to

81 Contact: linux-leds@vger.kernel.org
83 Signal the link speed state of 10Mbps of the named network device.
85 If set to 0 (default), the LED's normal state is off.
87 If set to 1, the LED's normal state reflects the link state
88 speed of 10MBps of the named network device.
89 Setting this value also immediately changes the LED state.
91 Present only if the named network device supports 10Mbps link speed.
93 What: /sys/class/leds/<led>/link_100
96 Contact: linux-leds@vger.kernel.org
98 Signal the link speed state of 100Mbps of the named network device.
100 If set to 0 (default), the LED's normal state is off.
102 If set to 1, the LED's normal state reflects the link state
103 speed of 100Mbps of the named network device.
104 Setting this value also immediately changes the LED state.
106 Present only if the named network device supports 100Mbps link speed.
108 What: /sys/class/leds/<led>/link_1000
111 Contact: linux-leds@vger.kernel.org
113 Signal the link speed state of 1000Mbps of the named network device.
115 If set to 0 (default), the LED's normal state is off.
117 If set to 1, the LED's normal state reflects the link state
118 speed of 1000Mbps of the named network device.
119 Setting this value also immediately changes the LED state.
121 Present only if the named network device supports 1000Mbps link speed.
123 What: /sys/class/leds/<led>/link_2500
126 Contact: linux-leds@vger.kernel.org
128 Signal the link speed state of 2500Mbps of the named network device.
130 If set to 0 (default), the LED's normal state is off.
132 If set to 1, the LED's normal state reflects the link state
133 speed of 2500Mbps of the named network device.
134 Setting this value also immediately changes the LED state.
136 Present only if the named network device supports 2500Mbps link speed.
138 What: /sys/class/leds/<led>/link_5000
141 Contact: linux-leds@vger.kernel.org
143 Signal the link speed state of 5000Mbps of the named network device.
145 If set to 0 (default), the LED's normal state is off.
147 If set to 1, the LED's normal state reflects the link state
148 speed of 5000Mbps of the named network device.
149 Setting this value also immediately changes the LED state.
151 Present only if the named network device supports 5000Mbps link speed.
153 What: /sys/class/leds/<led>/link_10000
156 Contact: linux-leds@vger.kernel.org

175 If set to 0 (default), the LED's normal state is off.
177 If set to 1, the LED's normal state reflects the link half
178 duplex state of the named network device.
179 Setting this value also immediately changes the LED state.
181 What: /sys/class/leds/<led>/full_duplex
184 Contact: linux-leds@vger.kernel.org
