The ioctl(2) is intended to provide more details about the cause of the down for the link. Eventually we might define a comprehensive list of codes for the situations. But interface also allows the driver to provide free-form null-terminated ASCII string to provide arbitrary non-formalized information. Sample implementation exists for mlx5(4), where the string is fetched from firmware controlling the port.
