In the talk we are proposing several *possible* solutions, with "pros" and "cons". We are open to new ideas, proposals and critique. I will play with implementing some of these ideas and to see if they pan-out. I want to acknowledge that Alexander Lobakin (+ co-authors) also have started coding on solutions here[3]. Lets see if we can collaborate and find a solution we can all agree on. --Jesper [1] Slide PDF: https://github.com/xdp-project/xdp-project/blob/master/conference/LLC2022/xdp_hints_hw_metadata-final.pdf [2] Slide source: https://github.com/xdp-project/xdp-project/tree/master/conference/LLC2022 [3] https://github.com/alobakin/linux/commits/xdp_hints
