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.
