> Subject: [PATCH v2 1/3] eventdev/eth_rx: add queue stats get and reset APIs
>
> This patch adds new api ``rte_event_eth_rx_adapter_queue_stats_get`` to
> retrieve queue stats. The queue stats are in the format
> ``struct rte_event_eth_rx_adapter_queue_stats``.
>
> For resetting the queue stats,
> ``rte_event_eth_rx_adapter_queue_stats_reset`` api is added.
>
> The adapter stats_get and stats_reset apis are also updated to
> handle queue level event buffer use case.
>
> Signed-off-by: Naga Harish K S V <[email protected]>
> ---
> v2:
> * added pmd callback support for adapter queue_stats_get and
> queue_stats_reset apis.
