The driver allocates a sg list per io struture based on a fixed maximum size. When it registers with the protocol transports and indicates the max sg list size it supports, the driver manipulates the fixed value to report a lesser amount so that it has reserved space for sg elements that are used for DIF. The driver initialization path sets the cfg_sg_seg_cnt field to the manipulated value for scsi. NVME initialization ran afterward and capped it's maximum by the manipulated value for SCSI. This erroneously made NVME report the SCSI-reduce-for-DIF value that reduced the max io size for nvme and wasted sg elements. Rework the driver so that cfg_sg_seg_cnt becomes the overall maximum size and allow the max size to be tunable. A separate (new) scsi sg count is then setup with the scsi-modified reduced value. NVME then initializes based off the overall maximum. Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Martin K.
