[SCSI] sd: Support disks formatted with DIF Type 2
Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands when protection is enabled. Only the 32-byte variants are supported. Implement support for issusing 32-byte READ/WRITE and enable Type 2 drives in the protection type detection logic. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
