    Support for controllers and disks that implement DIF protection
    information:

    - During command preparation the RDPROTECT/WRPROTECT must be set
    correctly if the target has DIF enabled.

    - READ(6) and WRITE(6) are not supported when DIF is on.

    - The controller must be told how to handle the I/O via the
    protection operation field in scsi_cmnd.

    - Refactor the I/O completion code that extracts failed LBA from the
    returned sense data and handle DIF failures correctly.

    - sd_dif.c implements the functions required to prepare and complete
    requests with protection information attached.
