net/mlx5e: Add hds-thresh query support via ethtool
Add support for reporting HDS (Header-Data Split) threshold via
ethtool. When applicable, mlx5 hardware splits packets of all sizes with
no configurable threshold, so report both hds-thresh and hds-thresh-max
as 0 (i.e. always split regardless of size).
