From 26af3072b035daadf34a99d02510f0ff98f41f90 Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Sun, 3 Dec 2006 14:51:14 -0200 Subject: [PATCH] [DCCP] ccid3: Fix warning message about illegal ACK This avoids a (harmless) warning message being printed at the DCCP server (the receiver of a DCCP half connection). 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.
