Subject: [PATCH v4 1/3] ethdev: add API for buffer recycle mode
Date: Thu, 23 Mar 2023 18:43:28 +0800	[thread overview]
Message-ID: <20230323104330.3823251-2-feifei.wang2@arm.com> (raw)
In-Reply-To: <20230323104330.3823251-1-feifei.wang2@arm.com>

There are 4 upper APIs for buffer recycle mode:
1. 'rte_eth_rx_queue_buf_recycle_info_get'
This is to retrieve buffer ring information about given ports's Rx
queue in buffer recycle mode. And due to this, buffer recycle can
be no longer limited to the same driver in Rx and Tx.

2. 'rte_eth_dev_buf_recycle'
Users can call this API to enable buffer recycle mode in data path.
There are 2 internal APIs in it, which is separately for Rx and TX.

3. 'rte_eth_tx_buf_stash'
Internal API for buffer recycle mode. This is to stash Tx used
buffers into Rx buffer ring.

4. 'rte_eth_rx_descriptors_refill'
Internal API for buffer recycle mode. This is to refill Rx
descriptors.

Above all APIs are just implemented at the upper level.
For different APIs, we need to define specific functions separately.
