Message-ID: <1392366970-11592-8-git-send-email-yangyingliang@huawei.com> Date: Fri, 14 Feb 2014 16:36:10 +0800 From: Yang Yingliang <yangyingliang@...wei.com> To: <netdev@...r.kernel.org> CC: <davem@...emloft.net>, <stephen@...workplumber.org> Subject: [PATCH net-next 7/7] sch_netem: clear old ecn when old qdisc's replaced If we set a netem qdisc with ecn option, while we use "#tc qdisc replace ..." that without ecn option to replace the old qdisc, the old ecn is still there. We need clear old ecn after qdisc's replaced.
