          This option allows you to specify the maximum number of scatter-

-         for most systems. However, the user may increase this up to 128.
-         Increasing this parameter will require significantly more memory
-         on a per controller instance. Increasing the parameter is not
-         necessary (or recommended) unless the user will be running
-         large I/O's via the raw interface.
+         gather entries per I/O. The driver default is 128, which matches
+         SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
