config FUSION
	tristate "Fusion MPT (base + ScsiHost) drivers"
	depends on PCI && SCSI
	---help---
	  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.

config FUSION_MAX_SGE
	int "Maximum number of scatter gather entries"
	depends on FUSION
	default "40"
	help
	  This option allows you to specify the maximum number of scatter-
	  gather entries per I/O. The driver defaults to 40, a reasonable number
	  for most systems. However, the user may increase this up to 128.
	  Increasing this parameter will require significantly more memory 
	  on a per controller instance. Increasing the parameter is not
	  necessary (or recommended) unless the user will be running 
	  large I/O's via the raw interface.

config FUSION_CTL
	tristate "Fusion MPT misc device (ioctl) driver"
	depends on FUSION
	---help---
	  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
	  will be compiled.

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

config FUSION_LAN
	tristate "Fusion MPT LAN driver"
	depends on FUSION && NET_FC
	---help---
	  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
	  will be compiled.

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