selftests: bpf: Make reuseport test output more legible
Include the name of the mismatching result in human readable format when reporting an error. The new output looks like the following: unexpected result result: [1, 0, 0, 0, 0, 0] expected: [0, 0, 0, 0, 0, 0] mismatch on DROP_ERR_INNER_MAP (bpf_prog_linum:153) check_results:FAIL:382 Signed-off-by: Lorenz Bauer <lmb@cloudflare.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Jakub Sitnicki <jakub@cloudflare.com> Acked-by: Martin KaFai Lau <kafai@fb.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Link: https://lore.kernel.org/bpf/20200124112754.19664-4-lmb@cloudflare.com
