From 13dae426318aae073028a4b3bd493104a991e800 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ilpo=20J=C3=A4rvinen?= Date: Fri, 10 Aug 2007 14:31:21 -0700 Subject: [PATCH] [TCP]: Update comment about highest_sack validity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This stale info came from the original idea, which proved to be unnecessarily complex, sacked_out > 0 is easy to do and that when it's going to be needed anyway (it _can_ be valid also when sacked_out == 0 but there's not going to be a guarantee about it for now).
