Incoming packets are both directed to * ccid_hc_rx_packet_recv() for the server half * ccid_hc_tx_packet_recv() for the client half The message gets printed since on a server the client half is currently not sending data packets. This is resolved for the moment by checking the DCCP-role first. In future times (bidirectional DCCP connections), this test may have to be more sophisticated.
