-/**
- * @ingroup qdisc
- * @defgroup fifo Packet/Bytes FIFO (pfifo/bfifo)
- * @brief
- *
- * The FIFO qdisc comes in two flavours:
- * @par bfifo (Byte FIFO)
- * Allows enqueuing until the currently queued volume in bytes exceeds
- * the configured limit.backlog contains currently enqueued volume in bytes.
- *
- * @par pfifo (Packet FIFO)
- * Allows enquueing until the currently queued number of packets
- * exceeds the configured limit.
- *
- * The configuration is exactly the same, the decision which of
- * the two variations is going to be used is made based on the
- * kind of the qdisc (rtnl_qdisc_set_kind()).
