Update qdisc if it already exists, otherwise attempting to add a qdisc which already exists will result in an error. This does not include changing the type of the qdisc, use --replace if you wish to do so.

Make the default answer for interactive prompts be 'y'es. This option is also required to delete all qdiscs on all network devices.
-k or --kind=TYPE
Only delete qdiscs of this type.
