> Yes, can you point me to the discussion? It has gone through many cycles :-( The linux-led list is probably the better archive to look through, it is a lot lower volume than netdev. https://www.spinics.net/lists/linux-leds/msg18652.html https://www.spinics.net/lists/linux-leds/msg18527.html > I post this as RFC for this exact reason...

Most of the discussion so far has been about PHY LEDs, where the PHY driver controls the LEDs. However some Ethernet switches also have LED controls, which are not part of the PHY. And then there are some MAC drivers which control the PHY in firmware, and have firmware calls for controlling the LEDs. We need a generic solution which scales across all this. And it needs to work without DT, or at least, not block ACPI being added later. But progress is slow. I hope that the PHY use case will drive things forward, get the ABI defined. We can then scale it out to include switches, maybe with a bit of code refactoring. Andrew
