Question related to this item specifically :) Do you want to individually send 4000 - 16000 (or more) TX stop / start events per second to userspace? :) At some point Heisenburg defeats low latency :) If not (and I hope not), perhaps also look into the net stack statistics already kept (or add more sampling stats if necessary), and instead trigger events based on sampling those statistics.
