From e61667af2f77d481411f2ccd307fed2247d785a8 Mon Sep 17 00:00:00 2001 From: Christoph Paasch Date: Sun, 10 Mar 2013 05:18:39 +0000 Subject: [PATCH] tcp: Remove unused tw_cookie_values from tcp_timewait_sock tw_cookie_values is never used in the TCP-stack. It was added by 435cf559f (TCPCT part 1d: define TCP cookie option, extend existing struct's), but already at that time it was not used at all, nor mentioned in the commit-message.
