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