From b9df3cb8cf9a96e63dfdcd3056a9cbc71f2459e7 Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Tue, 14 Nov 2006 11:21:36 -0200 Subject: [TCP/DCCP]: Introduce net_xmit_eval Throughout the TCP/DCCP (and tunnelling) code, it often happens that the return code of a transmit function needs to be tested against NET_XMIT_CN which is a value that does not indicate a strict error condition. This patch uses a macro for these recurring situations which is consistent with the already existing macro net_xmit_errno, saving on duplicated code.
