Message-Id: <20191023161632.541-2-stephen@networkplumber.org> Date: Wed, 23 Oct 2019 09:16:30 -0700 From: Stephen Hemminger <stephen@...workplumber.org> To: netdev@...r.kernel.org Cc: Stephen Hemminger <stephen@...workplumber.org> Subject: [PATCH iproute2 1/3] examples: remove out of date cbq stuff The examples around cbq are out of date and never updated. There are better ways to achieve same kind of thing with more modern qdisc.
