当我运行下面的代码时，我得到的错误中没有10022 sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1) ，出什么问题了？

@staticmethod
    def _open(suffix, dscp):
        error, sock = ovs.socket_util.inet_open_active(socket.SOCK_STREAM,
                                                       suffix, 0, dscp)
        if not error:
            try:
                sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
            except socket.error as e:
                print("error: {}".format(e))
                sock.close()
                return ovs.socket_util.get_exception_errno(e), None
        return error, sock
