0069 This option allows you to specify the maximum number of scatter-
0070 gather entries per I/O. The driver default is 128, which matches
0071 SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
0072 Decreasing this parameter will reduce memory requirements

0079 The Fusion MPT misc device driver provides specialized control
0080 of MPT adapters via system ioctl calls. Use of ioctl calls to
0081 the MPT driver requires that you create and use a misc device
0082 node ala:
0083 mknod /dev/mptctl c 10 240
0084
0085 One use of this ioctl interface is to perform an upgrade (reflash)
0086 of the MPT adapter firmware. Refer to readme file(s) distributed
0087 with the Fusion MPT linux driver for additional details.
0088
0089 If enabled by saying M to this, a driver named: mptctl
