IPv6: add "disable" module parameter support to ipv6.ko
Add "disable" module parameter support to ipv6.ko by specifying "disable=1" on module load. We just do the minimum of initializing inetsw6[] so calls from other modules to inet6_register_protosw() won't OOPs, then bail out. No IPv6 addresses or sockets can be created as a result, and a reboot is required to enable IPv6. Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

+
+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.
