Subject: [PATCH net-next 0/7] clear old options when old qdisc's replaced
Date: Fri, 14 Feb 2014 16:36:03 +0800	[thread overview]
Message-ID: <1392366970-11592-1-git-send-email-yangyingliang@huawei.com> (raw)

I've added a netem qdisc with rate option, then I replace this qdisc
without rate option but with latency option. The rate option is still
there.

E.g.
  # tc qdisc add dev eth4 handle 1: root netem rate 10mbit
  # tc qdisc show
    qdisc netem 1: dev eth4 root refcnt 2 limit 1000 rate 10Mbit

  # tc qdisc replace dev eth4 handle 1: root netem latency 10ms
  # tc qdisc show
    qdisc netem 1: dev eth4 root refcnt 2 limit 1000 delay 10.0ms rate 10Mbit

The old options need be cleared after the qdisc is replaced.

Yang Yingliang (7):
  sch_netem: clear old clgstate when old qdisc's replaced
  sch_netem: clear old dist table when old qdisc's replaced
  sch_netem: clear old reorder when old qdisc's replaced
  sch_netem: clear old correlation when old qdisc's replaced
  sch_netem: clear old corrupt when old qdisc's replaced
  sch_netem: clear old rate when old qdisc's replaced
  sch_netem: clear old ecn when old qdisc's replaced
