From 0b6a05c1dbebe8c616e2e5b0f52b7a01fd792911 Mon Sep 17 00:00:00 2001 From: Ilpo Järvinen Date: Tue, 15 Sep 2009 01:30:10 -0700 Subject: tcp: fix ssthresh u16 leftover MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It was once upon time so that snd_sthresh was a 16-bit quantity. ...That has not been true for long period of time. I run across some ancient compares which still seem to trust such legacy. Put all that magic into a single place, I hopefully found all of them. Compile tested, though linking of allyesconfig is ridiculous nowadays it seems. Signed-off-by: Ilpo Järvinen Signed-off-by: David S.
