From: Pavan Nikhilesh <pbhagavat...@marvell.com>
Include vector configuration into the structure
``rte_event_eth_rx_adapter_queue_conf`` used when configuring rest
of the Rx adapter ethernet device Rx queue parameters.
This simplifies event vector configuration as it avoids splitting
configuration per Rx queue.
