Why not? It is just a plain boring LED. It can be used for anything, heartbeat, panic SOS in Morse code, shift lock, disk activity. Any of the triggers can be applied to it. It can be found in /sys/class/leds/f1072004.mdio-mii:00:WAN. But when we come to using it for ledtrig-netdev, the user is more likely to follow /sys/class/net/eth0/phydev/leds/f1072004.mdio-mii\:00\:WAN/ > (Plus the netdev trigger should be tested; we'll > need some kind of link to the ethernet device if we want this to work > on multi-ethernet systems). Since this is a plain boring LED, it could actually blink for any netdev. When we get to offloading blinking to hardware, then things change, we need to check the netdev which is configured in the ledtrig-netdev is the same one the PHY is associated to. But i have a patchset for that which will appear later. > Should documentation be added to Documentation/leds/well-known-leds.txt ? Saying what. That there might be LEDs in your RJ45 connector, which can be used for anything which is supported by an Linux LED trigger? Andrew
