Hi Toke, here is a target with lot of interest for it : www.gtp-guard.orgWhen dealing with mobile network data-plane, at some point you have ordering issues and shaping needs, so queuing is truly needed. Alternatively ones can implement PIFO or others built on AF_XDP but if dedicated bpf map covers the use-case, would be nice.
Watching at your LPC 2022 presentation, at the end, discussions where made around using existing Qdisc kernel framework and find a way to share the path between XDP and netstack. Is it a target for adding PIFO, or more generally getting queuing support for XDP ?

After that, and some thorough testing, it should be possible to post another revision. What's your interest in this? I.e., what do you want to use them for? Would be useful to know so I can make sure this is covered :) -Toke
