-+ * device_name - network device name to monitor
-+ *
-+ * interval - duration of LED blink, in milliseconds
-+ *
-+ * mode - either "none" (LED is off) or a space separated list of one or more of:
-+ *   link: LED's normal state reflects whether the link is up (has carrier) or not
-+ *   tx:   LED blinks on transmitted data
