Andrew,

Thanks for the links - the most recent attempt does look promising.
For whatever reason I don't have that series in my mail history so
it's not clear how I can respond to it.

Ansuel, are you planning on posting a v7 of 'Adds support for PHY LEDs
with offload triggers' [1]?

I'm not all that familiar with netdev led triggers. Is there a way to
configure the default offload blink mode via dt with your series? I
didn't quite follow how the offload function/blink-mode gets set.

Best Regards,

Tim
