[dpdk-dev] [PATCH v3 1/4] drivers: add queue parameter in event processing callback

[Nipun Gupta <nipun.gupta@nxp.com>]

For event dequeues for ethernet queues, a dpaa2_queue structure is
required to get the configuration for that ethernet queue. Based on
this configuration the rte_event is to be filled at the ingress side.
