ipruote2-5.15 fails to compile due an undefined reference to bpf_load_program. libbpf removed bpf_load_program in 1.0.0 with 9476dce6fe90 ("libbpf: remove deprecated low-level APIs") [1]

iproute2 5.18 compiles fine with libbpf 1.0.0, hence may I suggest to stable iproute2 5.18 (or maybe even 5.19) and drop 5.15?
