6config IPV6
7	tristate "The IPv6 protocol"
8	default m
9	---help---
10	  This is complemental support for the IP version 6.
11	  You will still be able to do traditional IPv4 networking as well.
12
13	  For general information about IPv6, see
14	  <http://playground.sun.com/pub/ipng/html/ipng-main.html>.
15	  For Linux IPv6 development information, see <http://www.linux-ipv6.org>.
16	  For specific information about IPv6 under Linux, read the HOWTO at
17	  <http://www.bieringer.de/linux/IPv6/>.
18
19	  To compile this protocol support as a module, choose M here: the
20	  module will be called ipv6.

22config IPV6_PRIVACY
23	bool "IPv6: Privacy Extensions support"
24	depends on IPV6
25	---help---
26	  Privacy Extensions for Stateless Address Autoconfiguration in IPv6
27	  support.  With this option, additional periodically-alter
28	  pseudo-random global-scope unicast address(es) will assigned to
29	  your interface(s).
30
31	  We use our standard pseudo random algorithm to generate randomized
32	  interface identifier, instead of one described in RFC 3041.
33
34	  By default, kernel do not generate temporary addresses.
35	  To use temporary addresses, do
36
37	        echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
38
39	  See <file:Documentation/networking/ip-sysctl.txt> for details.

41config IPV6_ROUTER_PREF
42	bool "IPv6: Router Preference (RFC 4191) support"
43	depends on IPV6
44	---help---
45	  Router Preference is an optional extension to the Router
46	  Advertisement message to improve the ability of hosts
47	  to pick more appropriate router, especially when the hosts
48	  is placed in a multi-homed network.
49
50	  If unsure, say N.

52config IPV6_ROUTE_INFO
53	bool "IPv6: Route Information (RFC 4191) support (EXPERIMENTAL)"
54	depends on IPV6_ROUTER_PREF && EXPERIMENTAL
55	---help---
56	  This is experimental support of Route Information.
57
58	  If unsure, say N.
