Then define a dctcp dedicated post_socket_cb callback stg_post_socket_cb(), invoking both settcpca() and bpf_map_update_elem() in it, and set it in test_dctcp(). For passing map_fd into stg_post_socket_cb() callback, a new member map_fd is added in struct cb_opts. Add another "const struct network_helper_opts *cli_opts" to do_test() to separate it from the server "opts".
