       Rx queue configuration structure

       Flags for handling received packets

   uint16_tservicing_weight
       Relative polling frequency of ethernet receive queue when the adapter uses a service core function for
       ethernet to event device transfers. If it is set to zero, the Rx queue is interrupt driven (unless rx
       queue interrupts are not enabled for the ethernet device).

       Definition at line 163 of file rte_event_eth_rx_adapter.h.

   structrte_eventev
       The values from the following event fields will be used when queuing mbuf events:

       • event_queue_id: Targeted event queue ID for received packets.

       • event_priority:  Event  priority  of  packets  from  this Rx queue in the event queue relative to other
         events.

       • sched_type: Scheduling type for packets from this Rx queue.

       • flow_id: If the RTE_ETH_RX_EVENT_ADAPTER_QUEUE_FLOW_ID_VALID bit is set in rx_queue_flags, this flow_id
         is used for all packets received from this queue. Otherwise the flow ID is set to the RSS hash  of  the
         src and dst IPv4/6 addresses.

       The event adapter sets ev.event_type to RTE_EVENT_TYPE_ETHDEV in the enqueued event.

   structrte_mempool*vector_mp
       Indicates the mempool that should be used for allocating rte_event_vector container. Should be created by
       using rte_event_vector_pool_create. Valid when RTE_EVENT_ETH_RX_ADAPTER_QUEUE_EVENT_VECTOR flag is set in
