From c5e7af0df5d7234afd8596560d9f570cfc6c18bf Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Fri, 23 Feb 2007 16:22:06 -0800 Subject: [TCP]: Correct reordering detection change (no FRTO case) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The reordering detection must work also when FRTO has not been used at all which was the original intention of mine, just the expression of the idea was flawed.
