From 52cf3cc8acea52ecb93ef1dddb4ef2ae4e35c319 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ilpo=20J=C3=A4rvinen?= Date: Sat, 18 Apr 2009 05:48:48 +0000 Subject: [PATCH] tcp: fix mid-wq adjustment helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Just noticed while doing some new work that the recent mid-wq adjustment logic will misbehave when FACK is not in use (happens either due sysctl'ed off or auto-detected reordering) because I forgot the relevant TCPCB tagbit.
