Subject: RE: [PATCH v3] net/mlx5: fix the sysfs port name translation
Date: Mon, 27 Mar 2023 15:00:08 +0000	[thread overview]
Message-ID: <DM4PR12MB5389647A8308C03685B003B6DF8B9@DM4PR12MB5389.namprd12.prod.outlook.com> (raw)
In-Reply-To: <20230323105414.724908-1-bingz@nvidia.com>



From: Bing Zhao 
> With some OFED or upstream kernel of mlx5, the port name fetched from
> "/sys/class/net/[DEV]/phys_port_name" may have a tailing "\n" as the EOL.
> The sscanf() will return the scanned items number with this EOL.
> 
> In such case, the "equal to" condition is considered as false and the function
> mlx5_translate_port_name() will recognize the port type wrongly with
> UNKNOWN result.
> 
> The tailing carriage return character should be removed before calling the
> mlx5_translate_port_name(), this was already done in the NL message
> handling. In the meanwhile, the possible incorrect line feed character is also
> taken into consideration.
> 
> Fixes: 654810b56828 ("common/mlx5: share Netlink commands")
> Fixes: 420bbdae89f2 ("net/mlx5: fix host physical function representor
> naming")
