Subject: [PATCH] net/mlx5: fix missing thread safety flag for flow API
Date: Mon, 23 Oct 2023 13:23:02 +0300	[thread overview]
Message-ID: <20231023102303.1443105-1-dsosnowski@nvidia.com> (raw)

When mlx5 port was configured with HW Steering flow engine
(devarg dv_flow_en set to 2), PMD did not set
RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE in device flags.
This caused certain flow API calls, such as rte_flow_query(),
to obtain a port-wide lock, which is not needed.

This patch adds missing code for setting this flag.

Fixes: d84c3cf7662c ("net/mlx5: introduce hardware steering enable routine")
