Bug Fixes in this Version

4146543

Description: Fixed data access race condition by separating the cq_ci from the configuration data spaces.

Keywords: cq_ci

Discovered in Version: MLNX DPDK 22.11.1

Fixed in Release: MLNX_DPDK_22.11_2310.5.1

4160541

Description: Latency of rte_eth_dev_mac_addr_add() increases with each new MAC address added. Changed the logic to only insert new MAC address rules when adding new MAC to remove the duplications of rules creation and to delete all other MACs to save time.

Keywords: rte_eth_dev_mac_addr_add, MAC

Fixed in Release: MLNX_DPDK_22.11_2310.5.1

4160535

Description: rte_eth_dev_start() performs unnecessary recreation of mlx5 control flow rules, resulting in increased delay of rte_eth_dev_start(). Rework the configuration restore in ethdev and mlx5 PMD layer to separate the promiscuous mode setting, all multicast mode setting and each MAC address setting and restore the config only when needed to save the startup time.

Keywords: rte_eth_dev_start(), ethdev, mlx5 PMD
