>When eth port queue is removed from Rx adapter using
>rte_event_eth_rx_adapter_queue_del() it incorrectly
>initializes CQ context instead of modifying it. This
>might lead to a crash when CQ context is modified
>as a part of rte_eth_dev_stop() sequence as CQ will
>hold invalid entries. This is responsibility of an
>application to call rte_event_eth_rx_adapter_queue_del()
>to remove eth port queue from Rx adapter in tear down
>sequence.
