| range 16 256 |
| ---help--- |
| This option allows you to specify the maximum number of scatter- |
| gather entries per I/O. The driver default is 128, which matches |
| MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this |
| can be 256. However, it may decreased down to 16. Decreasing this |
| parameter will reduce memory requirements on a per controller instance. |
