The name of the device can only be changed when the interface is down. Is it possible to put some scripting around it to detach and attach the leds to the interfaces on ifup/ifdown triggers?Are the led triggers available for using while the netdev is down then?Sure! On embedded systems triggers are usually attached to actual LEDs at probe time using default_trigger field of struct led_classdev, and that can be specified both in machine files or in device tree.
I also think that led triggers should be available. I asked the question because detach & attach leds to interfaces would indeed break that. btw, I tried to send a patch tuesday (my first $ git send-email) using netdev notifiers: did you receive it, and what do you think of it? Kurt
