|
|
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.
