| 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. |

| 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. |

| 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. |

| 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. |

| 64 | If unsure whether you really want or need this, say N. |
