This option allows you to specify the maximum number of scatter-
- gather entries per I/O. The driver defaults to 40, a reasonable number
- 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.
