Subject: [PATCH v3] net/mlx5: fix the error set in control tables create
Date: Fri, 30 Jun 2023 12:46:35 +0300 [thread overview]
Message-ID: <20230630094635.434124-1-bingz@nvidia.com> (raw)
In-Reply-To: <20230630092551.434020-1-bingz@nvidia.com>
When some failure occurs in the flow_hw_create_ctrl_tables(), the
"rte_flow_error" should be set properly with all needed information.
Then the rte_errno and the "message" will reflect the actual failure.
This will also solve the crash when trying to access the "message".
Fixes: 1939eb6f660c ("net/mlx5: support flow port action with HWS")
Fixes: 483181f7b6dd ("net/mlx5: support device control of representor matching")
Fixes: ddb68e47331e ("net/mlx5: add extended metadata mode for HWS")
