- *
- * 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
- * rx: LED blinks on receive data

- *
- * Simple link status LED:
