From 5e19e3fcd7351de1ca87c4797cca27ba55c7e55e Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Mon, 27 Nov 2006 12:28:48 -0200 Subject: [PATCH] [DCCP] ccid3: Resolve small FIXME This considers the case - ACK received while no packet has been sent so far. Resolved by printing a (rate-limited) warning message. Further removes an unnecessary BUG_ON in ccid3_hc_tx_packet_recv, received feedback on a terminating connection is simply ignored.
