50 * A packet can be identified by hardware as different flow types. Different
51 * NIC hardwares may support different flow types.
52 * Basically, the NIC hardware identifies the flow type as deep protocol as
53 * possible, and exclusively. For example, if a packet is identified as
54 * 'RTE_ETH_FLOW_NONFRAG_IPV4_TCP', it will not be any of other flow types,
55 * though it is an actual IPV4 packet.
