Converting to Linux native format. However the isci driver does a lot of the calculation based on the max size of this data structure and the Linux data structure only has a pointer to the response data. Thus the sizeof(struct ssp_response_iu) will be incorrect and we need to define the max size. Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
