DESCRIPTION
       The nl-qdisc tools allow to manage and configure queueing disciplines (qdiscs) in the kernel.


OPTIONS
       -h or --help
              Print help text to console and exit.

       -v or --version
              Print versioning information to console and exit.

       -q or --quiet
              Do not print informal notifications about actions taken to the console.  By default a short description
              of each qdisc added/update/deleted will be printed to the console. This option disables this behaviour.

       -d or --dev=DEV
              Network device the qdisc is attached to.

       -p or --parent=ID
              Identifier of the parent qdisc/class this qdisc is attached to. The  identifier  can  be  specified  as
              classid, name or one of the special values "root" or "ingress".

       -i or --id=ID
              Identifier of qdisc. It can be specified as classid or name.


   nl-qdisc-add Options
       --update
              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.

       --replace
              Replace or update qdisc if it already exists. Same behaviour as --update but  will  completely  replace
              the qdisc if it exists already.

       --update-only
              Update an existing qdisc but do not create it if it does not exist.

       --replace-only
              Update or replace an existing qdisc but do not create it if it does exist.


   nl-qdisc-delete Options
       --interactive
              The  interactive  mode requires confirmation by the user for each qdisc deleted. It will print a prompt

       --stats
              Show  statistics  information for each qdisc listed. This option will also turn on detailed information
              automatically.

       -r or --recursive
              List all TC objects recurisvely attached to all qdiscs matching the filter.

       -k or --kind=TYPE
              Only list qdiscs of this type.


USAGE
       Add a HTB root qdisc with id "5:":

              nl-qdisc-add --dev eth0 --parent root --id 5: htb

       List all qdiscs on eth0 and print statistical data:
