The only use case now is in test_bpf_ip_check_defrag_ok which ends up bypassing most (or at least some) of the connect_to_fd_opts() logic. It's much better that test should have its own connect_to_fd_opts() instead. This patch adds a new "type" parameter for connect_to_fd_opts(), then opts->type can be replaced by "type" parameter in it. In test_bpf_ip_check_defrag_ok, different types are passed to it. And the strcut member "type" of network_helper_opts can be dropped now.
