5 # IPv6 as module will cause a CRASH if you try to unload it
7 tristate "The IPv6 protocol"
10 This is complemental support for the IP version 6.
11 You will still be able to do traditional IPv4 networking as well.
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/>.
19 To compile this protocol support as a module, choose M here: the
20 module will be called ipv6.
23 bool "IPv6: Privacy Extensions support"
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
31 We use our standard pseudo random algorithm to generate randomized
32 interface identifier, instead of one described in RFC 3041.
34 By default, kernel do not generate temporary addresses.
35 To use temporary addresses, do
37 echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr
39 See <file:Documentation/networking/ip-sysctl.txt> for details.
41 config IPV6_ROUTER_PREF
42 bool "IPv6: Router Preference (RFC 4191) support"
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.
52 config IPV6_ROUTE_INFO
53 bool "IPv6: Route Information (RFC 4191) support (EXPERIMENTAL)"
54 depends on IPV6_ROUTER_PREF && EXPERIMENTAL
56 This is experimental support of Route Information.
60 config IPV6_OPTIMISTIC_DAD
61 bool "IPv6: Enable RFC 4429 Optimistic DAD (EXPERIMENTAL)"
62 depends on IPV6 && EXPERIMENTAL
64 This is experimental support for optimistic Duplicate
65 Address Detection. It allows for autoconfigured addresses
66 to be used more quickly.
71 tristate "IPv6: AH transformation"
84 tristate "IPv6: ESP transformation"
88 <<<<<<< HEAD:net/ipv6/Kconfig
92 >>>>>>> 264e3e889d86e552b4191d69bb60f4f3b383135a:net/ipv6/Kconfig
99 Support for IPsec ESP.
104 tristate "IPv6: IPComp transformation"
107 select INET6_XFRM_TUNNEL
109 select CRYPTO_DEFLATE
111 Support for IP Payload Compression Protocol (IPComp) (RFC3173),
112 typically needed for IPsec.
117 tristate "IPv6: Mobility (EXPERIMENTAL)"
118 depends on IPV6 && EXPERIMENTAL
121 Support for IPv6 Mobility described in RFC 3775.
125 config INET6_XFRM_TUNNEL
134 config INET6_XFRM_MODE_TRANSPORT
135 tristate "IPv6: IPsec transport mode"
140 Support for IPsec transport mode.
144 config INET6_XFRM_MODE_TUNNEL
145 tristate "IPv6: IPsec tunnel mode"
150 Support for IPsec tunnel mode.
154 config INET6_XFRM_MODE_BEET
155 tristate "IPv6: IPsec BEET mode"
160 Support for IPsec BEET mode.
164 config INET6_XFRM_MODE_ROUTEOPTIMIZATION
165 tristate "IPv6: MIPv6 route optimization mode (EXPERIMENTAL)"
166 depends on IPV6 && EXPERIMENTAL
169 Support for MIPv6 route optimization mode.
172 tristate "IPv6: IPv6-in-IPv4 tunnel (SIT driver)"
177 Tunneling means encapsulating data of one protocol type within
178 another protocol and sending it over a channel that understands the
179 encapsulating protocol. This driver implements encapsulation of IPv6
180 into IPv4 packets. This is useful if you want to connect two IPv6
181 networks over an IPv4-only path.
183 Saying M here will produce a module called sit.ko. If unsure, say Y.
186 tristate "IPv6: IPv6-in-IPv6 tunnel"
190 Support for IPv6-in-IPv6 tunnels described in RFC 2473.
194 config IPV6_MULTIPLE_TABLES
195 bool "IPv6: Multiple Routing Tables"
196 depends on IPV6 && EXPERIMENTAL
199 Support multiple routing tables.
202 bool "IPv6: source address based routing"
203 depends on IPV6_MULTIPLE_TABLES
205 Enable routing by source address or prefix.
207 The destination address is still the primary routing key, so mixing
208 normal and source prefix specific routes in the same routing table
209 may sometimes lead to unintended routing behavior. This can be
210 avoided by defining different routing tables for the normal and
211 source prefix specific routes.
