CONFIG_FUSION
  LSI Logic Fusion(TM) Message Passing Technology (MPT) device support
  provides high performance SCSI host initiator, and LAN [1] interface
  services to a host system.  The Fusion architecture is capable of
  duplexing these protocols on high-speed Fibre Channel
  (up to 2 GHz x 2 ports = 4 GHz) and parallel SCSI (up to Ultra-320)
  physical medium.

          [1] LAN is not supported on parallel SCSI medium.

  These drivers require a Fusion MPT compatible PCI adapter installed
  in the host system.  MPT adapters contain specialized I/O processors
  to handle I/O workload, and more importantly to offload this work
  from the host CPU(s).

  If you have Fusion MPT hardware and want to use it, you can say
  Y or M here to add MPT (base + ScsiHost) drivers.
    <Y> = build lib (fusion.o), and link [static] into the kernel [2]
          proper
    <M> = compiled as [dynamic] modules [3] named: (mptbase.o,
          mptscsih.o)

          [2] In order enable capability to boot the linux kernel
              natively from a Fusion MPT target device, you MUST
               answer Y here! (currently requires CONFIG_BLK_DEV_SD)
          [3] This support is also available as a module ( = code
              which can be inserted in and removed from the running
              kernel whenever you want).  If you want to compile as
              modules, say M here and read
              <file:Documentation/modules.txt>.

  If unsure, say N.

  If you say Y or M here you will get a choice of these
  additional protocol and support module options:         Module Name:
    <M>   Enhanced SCSI error reporting                     (isense.o)
    <M>   Fusion MPT misc device (ioctl) driver             (mptctl.o)
    <M>   Fusion MPT LAN driver                             (mptlan.o)

  Fusion MPT is trademark of LSI Logic Corporation, and its
  architecture is based on LSI Logic's Message Passing Interface (MPI)
  specification.

CONFIG_FUSION_ISENSE
  The isense module (roughly stands for Interpret SENSE data) is
  completely optional.  It simply provides extra English readable
  strings in SCSI Error Report(s) that might be generated from the
  Fusion MPT SCSI Host driver, for example when a target device
  returns a SCSI check condition on a I/O.  Without this module
  loaded you might see:

    SCSI Error Report =-=-= (ioc0,scsi5:0)
      SCSI_Status=02h (CHECK_CONDITION)
      Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00
      SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00
      SenseKey=2h (NOT READY); FRU=02h
      ASC/ASCQ=29h/00h

  Where otherwise, if this module had been loaded, you would see:

    SCSI Error Report =-=-= (ioc0,scsi5:0)
      SCSI_Status=02h (CHECK_CONDITION)
      Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00 - "WRITE(10)"
      SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00
      SenseKey=2h (NOT READY); FRU=02h
      ASC/ASCQ=29h/00h "LOGICAL UNIT NOT READY, INITIALIZING CMD. REQUIRED"

  Say M for "Enhanced SCSI error reporting" to compile this optional module,
  creating a driver named: isense.o.

  NOTE: Support for building this feature into the kernel is not
  available, due to kernel size considerations.

CONFIG_FUSION_CTL
  The Fusion MPT misc device driver provides specialized control
  of MPT adapters via system ioctl calls.  Use of ioctl calls to
  the MPT driver requires that you create and use a misc device
  node ala:
    mknod /dev/mptctl c 10 240

  One use of this ioctl interface is to perform an upgrade (reflash)
  of the MPT adapter firmware.  Refer to readme file(s) distributed
  with the Fusion MPT linux driver for additional details.

  If enabled by saying M to this, a driver named: mptctl.o
  will be compiled.

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

CONFIG_FUSION_LAN
  This module supports LAN IP traffic over Fibre Channel port(s)
  on Fusion MPT compatible hardware (LSIFC9xx chips).
  The physical interface used is defined in RFC 2625.
  Please refer to that document for details.

  Installing this driver requires the knowledge to configure and
  activate a new network interface, "fc0", using standard Linux tools.

  If enabled by saying M to this, a driver named: mptlan.o
  will be compiled.

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

  NOTES: This feature is NOT available nor supported for linux-2.2.x
  kernels.  You must be building a linux-2.3.x or linux-2.4.x kernel
  in order to configure this option.
  Support for building this feature into the linux kernel is not
  yet available.

CONFIG_NET_FC
  Fibre Channel is a high speed serial protocol mainly used to connect
  large storage devices to the computer; it is compatible with and
  intended to replace SCSI.

  If you intend to use Fibre Channel, you need to have a Fibre channel
  adaptor card in your computer; say Y here and to the driver for your
  adaptor below. You also should have said Y to "SCSI support" and
  "SCSI generic support".
