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.

Right, that's why I think the only way is to use device name.

I asked the question because detach & attach leds to interfaces would
indeed break that.

Sure? I think that the trigger would be set again on reattach, as
default_trigger is checked both in led_cdev probe and
trigger_register, see:

I'll try that tonight.

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?

Sure, I got it!  I was planning to try that this weekend but I can
give you some comments earlier tonight... sorry for the dealy!

Fabio
