v11: - new patches 2, 4, 6. - drop expect_errno from network_helper_opts as Eduard and Martin suggested. - drop sockmap_ktls patches from this set. - add a new helper connect_fd_to_addr_str.
v10: - a new patch 10 is added. - patches 1-6, 8-9 unchanged, only commit logs updated. - "err = -errno" is used in patches 7, 11, 12 to get the real error number before checking value of "err".
v9: - new patches 5-7, new struct member expect_errno for network_helper_opts. - patches 1-4, 8-9 unchanged. - update patches 10-11 to make sure all tests pass.
v8: - only patch 8 updated, to fix errors reported by CI.
v7: - address Martin's comments in v6. (thanks) - use MAX(opts->backlog, 0) instead of opts->backlog. - use connect_to_fd_opts instead connect_to_fd. - more ASSERT_* to check errors.
v6: - update patch 6 as Daniel suggested. (thanks)
v5: - keep make_server and make_client as Eduard suggested.
v4: - a new patch to use make_sockaddr in sockmap_ktls. - a new patch to close fd in error path in drop_on_reuseport. - drop make_server() in patch 7. - drop make_client() too in patch 9.
v3: - a new patch to add backlog for network_helper_opts. - use start_server_str in sockmap_ktls now, not start_server.
v2: - address Eduard's comments in v1. (thanks) - fix errors reported by CI.
This patch set uses network helpers in sk_lookup, and drop the local helpers inetaddr_len() and make_socket().
