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 and getsockopt(SO_TYPE) can be replaced by "type" parameter in it. In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass it to connect_to_fd_opts(). In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW" and "SOCK_DGRAM" are passed to it. With these changes, the strcut member "type" of network_helper_opts can be dropped now.
