  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
  73          on a per controller instance.

  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.

  92          If unsure whether you really want or need this, say N.

  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.
