> With some OFED or upstream kernel of mlx5, the port name fetched from

> 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
