[bpf-next,v9,05/11] selftests/bpf: Add network_helper_opts for connect_fd_to_fd

Message ID 7b0985069599970cb45187a1590670372ed1579b.1720276189.git.tanggeliang@kylinos.cn (mailing list archive)

From: Geliang Tang <tanggeliang@kylinos.cn>

To make connect_fd_to_fd() more flexible, use a struct network_helper_opts
parameter "opts" instead of timeout_ms. With this change, other opts like
"must_fail" can be used in connect_fd_to_fd() too.
