Description

When attempting to send a connection response (CR) without any data using:

        osmo_sccp_tx_conn_resp(scu, scu_prim->u.connect.conn_id,
                     &scu_prim->u.connect.called_addr,
                     NULL, 0);

Wireshark displays a malformed packet. To me it looks like if there is an optional parameter (the data part) announced, but the data is (of course) not there. However. CR seems to work fine when no data is attached.
