[SCSI] sd: Identify DIF protection type and application tag ownership
If a disk is formatted with protection information (Inquiry bit
PROTECT=1) it is required to support Read Capacity(16). Force use of
the 16-bit command in this case and extract the P_TYPE field which
indicates whether the disk is formatted using DIF Type 1, 2 or 3.
The ATO (App Tag Own) bit in the Control Mode Page indicates whether
the storage device or the initiator own the contents of the
DIF application tag.
