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.

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
