Well yes that's the fun part. netdev really liked the concept and how it
was implemented (and actually also liked the use of a dedicated trigger
instead of bloating the netdev trigger)

But I never got a review from LED team and that result in having the
patch stalled and never merged... But ok I will recover the work and
recheck/retest everything from the start hoping to get more traction
now...
