> + * RTE Flow Classify Library
> + *
> + * This library provides flow record information with some measured properties.
> + *
> + * Application should define the flow and measurement criteria (action) for it.
> + *
> + * Library doesn't maintain any flow records itself, instead flow information is
> + * returned to upper layer only for given packets.
> + *
> + * It is application's responsibility to call rte_flow_classify_query()
> + * for group of packets, just after receiving them or before transmitting them.
> + * Application should provide the flow type interested in, measurement to apply
> + * to that flow in rte_flow_classify_create() API, and should provide
> + * rte_flow_classify object and storage to put results in
> + * rte_flow_classify_query() API.
> + *
> + *  Usage:
> + *  - application calls rte_flow_classify_create() to create a rte_flow_classify
> + *    object.
> + *  - application calls rte_flow_classify_query() in a polling manner,
> + *    preferably after rte_eth_rx_burst(). This will cause the library to
> + *    convert packet information to flow information with some measurements.
> + *  - rte_flow_classify object can be destroyed when they are no more needed
> + *    via rte_flow_classify_destroy()
