> 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.
