Otherwise it won't show up until 5.11. It would be good for Bullseye to have the option to use libbpf with iproute2. If Debian uses the 5.10 kernel then it should use the 5.10 version of iproute2 and 5.10 version libbpf. All the components align with consistent versioning. I have some use cases I can move from bpftool loading to iproute2 as additional testing to what Hangbin has already done. If that goes well, I can re-send the patch series against iproute2-main branch by next weekend. It would be good for others (Jesper, Toke, Jiri) to run their own testing as well.
