56 | ---help--- | |
57 | This option allows you to specify the maximum number of scatter- | |
58 | gather entries per I/O. The driver default is 128, which matches | |
59 | SAFE_PHYS_SEGMENTS. However, it may decreased down to 16. | |
60 | Decreasing this parameter will reduce memory requirements | |
61 | on a per controller instance. | |
