BASICS
file 'dev' contains the device numbers corresponding to this device. The links
'device' and 'driver' point to the SCSI device and driver entries.
+Each directory also contains the entry 'options' which shows the currently
+enabled driver and mode options. The value in the file is a bit mask where the
+bit definitions are the same as those used with MTSETDRVBUFFER in setting the
+options.
+
A link named 'tape' is made from the SCSI device directory to the class
directory corresponding to the mode 0 auto-rewind device (e.g., st0).
MT_ST_SYSV sets the SYSV semantics (mode)
MT_ST_NOWAIT enables immediate mode (i.e., don't wait for
the command to finish) for some commands (e.g., rewind)
+ MT_ST_SILI enables setting the SILI bit in SCSI commands when
+ reading in variable block mode to enhance performance when
+ reading blocks shorter than the byte count; set this only
+ if you are sure that the drive supports SILI and the HBA
+ correctly returns transfer residuals
MT_ST_DEBUGGING debugging (global; debugging must be
compiled into the driver)
MT_ST_SETBOOLEANS
