Subject: Re: [PATCH v2 16/17] leds: leds-nuc: add support for changing the
 ethernet type indicator

What possible configurations does this support?

Does this blink on rx/tx activity for a specific ethernet port?

There is a work in progress to add support for transparent offloading of
LED triggers, with the netdev trigger being the first target.

This means that after that is done, you could implement this driver so
that when netdev trigger is enabled on a supported interface, your
driver will offload the blinking to the HW.

This should probably also work for HDD activity, but this would need a
blockdev trigger first...
