-/**
- * @ingroup tc
- * @defgroup qdisc Queueing Disciplines
- *
- * @par Qdisc Handles
- * In general, qdiscs are identified by the major part of a traffic control
- * handle (the upper 16 bits). A few special values exist though:
- *  - \c TC_H_ROOT: root qdisc (directly attached to the device)
- *  - \c TC_H_INGRESS: ingress qdisc (directly attached to the device)
- *  - \c TC_H_UNSPEC: unspecified qdisc (no reference)
- *
- * @par 1) Adding a Qdisc
- * @code
- * // Allocate a new empty qdisc to be filled out
- * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
- *
- * // ... specify the kind of the Qdisc
- * rtnl_qdisc_set_kind(qdisc, "pfifo");
- *
- * // Specify the device the qdisc should be attached to
- * rtnl_qdisc_set_ifindex(qdisc, ifindex);
- *
- * // ... specify the parent qdisc
- * rtnl_qdisc_set_parent(qdisc, TC_H_ROOT);
- *
- * // Specifying the handle is not required but makes reidentifying easier
- * // and may help to avoid adding a qdisc twice.
- * rtnl_qdisc_set_handle(qdisc, 0x000A0000);
- *
- * // Now on to specify the qdisc specific options, see the relevant qdisc
- * // modules for documentation, in this example we set the upper limit of
- * // the packet fifo qdisc to 64
- * rtnl_qdisc_fifo_set_limit(qdisc, 64);
- *
- * rtnl_qdisc_add(handle, qdisc, NLM_R_REPLACE);
- *
- * // Free up the memory
- * rtnl_qdisc_put(qdisc);
- * @endcode
- *
- * @par 2) Deleting a Qdisc
- * @code
- * // Allocate a new empty qdisc to be filled out with the parameters
- * // specifying the qdisc to be deleted. Alternatively a fully equiped
- * // Qdisc object from a cache can be used.
- * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
- *
- * // The interface index of the device the qdisc is on and the parent handle
- * // are the least required fields to be filled out.
- * // Note: Specify TC_H_ROOT or TC_H_INGRESS as parent handle to delete the
- * //       root respectively root ingress qdisc.
- * rtnl_qdisc_set_ifindex(qdisc, ifindex);
- * rtnl_qdisc_set_parent(qdisc, parent_handle);
- *
- * // If required for identification, the handle can be specified as well.
- * rtnl_qdisc_set_handle(qdisc, qdisc_handle);
- *
- * // Not required but maybe helpful as sanity check, the kind of the qdisc
- * // can be specified to avoid mistakes.
- * rtnl_qdisc_set_kind(qdisc, "pfifo");
- *
- * // Finally delete the qdisc with rtnl_qdisc_delete(), alternatively
- * // rtnl_qdisc_build_delete_request() can be invoked to generate an
- * // appropritate netlink message to send out.
- * rtnl_qdisc_delete(handle, qdisc);
- *
- * // Free up the memory
- * rtnl_qdisc_put(qdisc);
- * @endcode
