DPDK offers pipeline model of packet processing. One of the key components of this model is the core to core packet exchange. rte_ring and rte_event_ring functions are 2 methods provided currently for core to core communication. However, these two do not separate the APIs from implementation. This does not allow using hardware queue implementations in pipeline model. This change adds queue APIs and driver framework so that HW queues can be used for core to core communication in pipeline model. When different implementations (ex: HW queues and rte_ring) are used for the same object in different platforms, it is important to make sure that the application is portable. Hence features of different implementations must be elevated to the API level, so that the application writers can make the right choice. Currently, basic APIs are created, will add more required APIs as this progresses.
