config IPV6
	tristate "The IPv6 protocol"
	default m
	---help---
	  This is complemental support for the IP version 6.
	  You will still be able to do traditional IPv4 networking as well.

	  For general information about IPv6, see
	  <http://playground.sun.com/pub/ipng/html/ipng-main.html>.
	  For Linux IPv6 development information, see <http://www.linux-ipv6.org>.
	  For specific information about IPv6 under Linux, read the HOWTO at
	  <http://www.bieringer.de/linux/IPv6/>.

	  To compile this protocol support as a module, choose M here: the 
	  module will be called ipv6.

config IPV6_PRIVACY
	bool "IPv6: Privacy Extensions support"
	depends on IPV6
	---help---
	  Privacy Extensions for Stateless Address Autoconfiguration in IPv6
	  support.  With this option, additional periodically-alter 
	  pseudo-random global-scope unicast address(es) will assigned to
	  your interface(s).
	
	  We use our standard pseudo random algorithm to generate randomized
	  interface identifier, instead of one described in RFC 3041.

	  By default, kernel do not generate temporary addresses.
	  To use temporary addresses, do
	
	        echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr 

	  See <file:Documentation/networking/ip-sysctl.txt> for details.

config IPV6_ROUTER_PREF
	bool "IPv6: Router Preference (RFC 4191) support"
	depends on IPV6
	---help---
	  Router Preference is an optional extension to the Router
	  Advertisement message to improve the ability of hosts
	  to pick more appropriate router, especially when the hosts
	  is placed in a multi-homed network.

	  If unsure, say N.

config IPV6_ROUTE_INFO
	bool "IPv6: Route Information (RFC 4191) support (EXPERIMENTAL)"
	depends on IPV6_ROUTER_PREF && EXPERIMENTAL
	---help---
	  This is experimental support of Route Information.

	  If unsure, say N.
