From 184d68b2b0b836587f92887b14baea41033ffeef Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Sat, 20 Sep 2008 21:21:16 -0700 Subject: [PATCH] tcp: No need to clear retransmit_skb_hint when SACKing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Because lost counter no longer requires tuning, this is trivial to remove (the tuning wouldn't have been too hard either) because no "new" retransmittable skb appeared below retransmit_skb_hint when SACKing for sure.
