57	help
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.
