range 16 128
|
help
|
This option allows you to specify the maximum number of scatter-
|
gather entries per I/O. The driver default is 128, which matches
|
SCSI_MAX_PHYS_SEGMENTS. However, it may decreased down to 16.
|
Decreasing this parameter will reduce memory requirements

on a per controller instance.

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.

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.

This turns on a logging facility that can be used to debug a number

|
The debug level can be programmed on the fly via SysFS (hex values)
|

echo [level] > /sys/class/scsi_host/host#/debug_level

There are various debug levels that can be found in the source:
