           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
