From b2ce49e7375ff5b9b133c474875dfbd97ef00ef7 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Fri, 9 May 2014 16:49:05 +0800 Subject: [PATCH] sch_hhf: fix comparison of qlen and limit When I use the following command, eth0 cannot send any packets. #tc qdisc add dev eth0 root handle 1: hhf limit 1 Because qlen need be smaller than limit, all packets were dropped. Fix this by qlen *<=* limit. Signed-off-by: Yang Yingliang Signed-off-by: David S.
