@ -335,3 +335,12 @@ Why: In 2.6.18 the Secmark concept was introduced to replace the "compat_net"
Secmark, it is time to deprecate the older mechanism and start the
process of removing the old code.
Who: Paul Moore <paul.moore@hp.com>
---------------------------
What: sysfs ui for changing p4-clockmod parameters
When: September 2009
Why: See commits 129f8ae9b1b5be94517da76009ea956e89104ce8 and
e088e4c9cdb618675874becb91b2fd581ee707e6.
Removal is subject to fixing any remaining bugs in ACPI which may
cause the thermal throttling not to happen at the right time.

Options for the ipv6 module are supplied as parameters at load time.
Module options may be given as command line arguments to the insmod
or modprobe command, but are usually specified in either the
/etc/modules.conf or /etc/modprobe.conf configuration file, or in a
distro-specific configuration file.
The available ipv6 module parameters are listed below. If a parameter
is not specified the default value is used.
The parameters are as follows:
disable
Specifies whether to load the IPv6 module, but disable all
its functionality. This might be used when another module
has a dependency on the IPv6 module being loaded, but no
IPv6 addresses or operations are desired.
The possible values and their effects are:
0
IPv6 is enabled.
This is the default value.
1
IPv6 is disabled.
No IPv6 addresses will be added to interfaces, and
it will not be possible to open an IPv6 socket.
A reboot is required to enable IPv6.
