From 089c34827e52346f0303d1e6a7b744c1f4da3095 Mon Sep 17 00:00:00 2001 From: Shan Wei Date: Sat, 19 Feb 2011 21:55:45 +0000 Subject: tcp: Remove debug macro of TCP_CHECK_TIMER Now, TCP_CHECK_TIMER is not used for debuging, it does nothing. And, it has been there for several years, maybe 6 years. Remove it to keep code clearer. Signed-off-by: Shan Wei Signed-off-by: David S.
