[dpdk-dev] [PATCHv3 1/5] ethdev: add new API to retrieve RX/TX queue information
Add the ability for the upper layer to query RX/TX queue information.
Add new structures:
struct rte_eth_rxq_info
struct rte_eth_txq_info
new functions:
rte_eth_rx_queue_info_get
rte_eth_tx_queue_info_get
into rte_etdev API.
Left extra free space in the queue info structures,
so extra fields could be added later without ABI breakage.
v2 changes:
- Add formal check for the qinfo input parameter.
- As suggested rename 'rx_qinfo/tx_qinfo' to 'rxq_info/txq_info'
v3 changes:
- Updated rte_ether_version.map
- Merged with latest changes
