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

78	help
79	  The Fusion MPT misc device driver provides specialized control
80	  of MPT adapters via system ioctl calls.  Use of ioctl calls to
81	  the MPT driver requires that you create and use a misc device
82	  node ala:
83	  mknod /dev/mptctl c 10 240
84
85	  One use of this ioctl interface is to perform an upgrade (reflash)
86	  of the MPT adapter firmware.  Refer to readme file(s) distributed
87	  with the Fusion MPT linux driver for additional details.
88
89	  If enabled by saying M to this, a driver named: mptctl
90	  will be compiled.

98	  This module supports LAN IP traffic over Fibre Channel port(s)
99	  on Fusion MPT compatible hardware (LSIFC9xx chips).
100	  The physical interface used is defined in RFC 2625.
101	  Please refer to that document for details.
102
103	  Installing this driver requires the knowledge to configure and
104	  activate a new network interface, "fc0", using standard Linux tools.
105
106	  If enabled by saying M to this, a driver named: mptlan
107	  will be compiled.

115	  of Fusion MPT related problems.
116
117	  The debug level can be programmed on the fly via SysFS (hex values)
118
