25  * A packet can be identified by hardware as different flow types. Different
26  * NIC hardwares may support different flow types.
27  * Basically, the NIC hardware identifies the flow type as deep protocol as
28  * possible, and exclusively. For example, if a packet is identified as
29  * 'RTE_ETH_FLOW_NONFRAG_IPV4_TCP', it will not be any of other flow types,
30  * though it is an actual IPV4 packet.
31  * Note that the flow types are used to define RSS offload types in
32  * rte_ethdev.h.
