This series got into net-next-2024-01-25--00-00, looking at the outputs it turns out that the iproute2 was crashing somewhere in libbpf :( I rebuilt latest iproute2 without libbpf support. It loads xdp_dummy.o just fine, so hopefully that's good enough for now, we'll see for sure in about 3 hours :)
