[PATCH 9/9] [TCP]: Avoid clearing sacktag hint in trivial situations

2007-09-20 Thread Ilpo Järvinen
There's no reason to clear the sacktag skb hint when small part of the rexmit queue changes. Account changes (if any) instead when fragmenting/collapsing. RTO/FRTO do not touch SACKED_ACKED bits so no need to discard SACK tag hint at all. Signed-off-by: Ilpo Järvinen [EMAIL PROTECTED] ---
