I had a patch series that did that; last posting was v3 back in November: https://marc.info/?l=linux-netdev&m=154221888012410&w=2 However, Eric raised some issues, also some Mellanox folks privately reported that using it in their driver regressed performance, and I've been too busy since to make progress with it. Since you seem to be much better than me at perf investigations, Jesper, maybe you could take over the series?
