This is the SCSI status byte as defined by the SCSI standard. Note that
it can have vendor information set in bits 0, 6 and 7 (although this
is uncommon).
Further note that this 'status' data does _not_ match the definitions in
<scsi/scsi.h> (e.g. CHECK_CONDITION). The following 'masked_status'
does match those definitions.

The type of status is unsigned char .
