4config FUSION
5	tristate "Fusion MPT (base + ScsiHost) drivers"
6	depends on PCI && SCSI
7	---help---
8	  LSI Logic Fusion(TM) Message Passing Technology (MPT) device support
9	  provides high performance SCSI host initiator, and LAN [1] interface
10	  services to a host system.  The Fusion architecture is capable of
11	  duplexing these protocols on high-speed Fibre Channel
12	  (up to 2 GHz x 2 ports = 4 GHz) and parallel SCSI (up to Ultra-320)
13	  physical medium.
14
15	  [1] LAN is not supported on parallel SCSI medium.

17config FUSION_MAX_SGE
18	int "Maximum number of scatter gather entries"
19	depends on FUSION
20	default "40"
21	help
22	  This option allows you to specify the maximum number of scatter-
23	  gather entries per I/O. The driver defaults to 40, a reasonable number
24	  for most systems. However, the user may increase this up to 128.
25	  Increasing this parameter will require significantly more memory
26	  on a per controller instance. Increasing the parameter is not
27	  necessary (or recommended) unless the user will be running
28	  large I/O's via the raw interface.

30config FUSION_CTL
31	tristate "Fusion MPT misc device (ioctl) driver"
32	depends on FUSION
33	---help---
34	  The Fusion MPT misc device driver provides specialized control
35	  of MPT adapters via system ioctl calls.  Use of ioctl calls to
36	  the MPT driver requires that you create and use a misc device
37	  node ala:
38	  mknod /dev/mptctl c 10 240
39
40	  One use of this ioctl interface is to perform an upgrade (reflash)
41	  of the MPT adapter firmware.  Refer to readme file(s) distributed
42	  with the Fusion MPT linux driver for additional details.
43
44	  If enabled by saying M to this, a driver named: mptctl
45	  will be compiled.
46
47	  If unsure whether you really want or need this, say N.
48
49config FUSION_LAN
50	tristate "Fusion MPT LAN driver"
51	depends on FUSION && NET_FC
52	---help---
53	  This module supports LAN IP traffic over Fibre Channel port(s)
54	  on Fusion MPT compatible hardware (LSIFC9xx chips).
55	  The physical interface used is defined in RFC 2625.
56	  Please refer to that document for details.
57
58	  Installing this driver requires the knowledge to configure and
59	  activate a new network interface, "fc0", using standard Linux tools.
60
61	  If enabled by saying M to this, a driver named: mptlan
62	  will be compiled.
63
64	  If unsure whether you really want or need this, say N.
