'extended tag' is important for XL710 performance, while might not be neccessary for other NICs. It adds the enabling 'extended tag' into i40e PMD specifically, then the sys files of 'extended_tag' and 'max_read_request_size', and all of their relavant operations are removed as they are not neccessary for all devices. In addition, documentations are updated at the same time.
