As IPV6_SUBTREES can't work without IPV6_MULTIPLE_TABLES have IPV6_SUBTREES depend on it. Signed-off-by: Ville Nuorvala <vnuorval@tcs.hut.fi> Signed-off-by: David S. Miller <davem@davemloft.net>

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

To compile this protocol support as a module, choose M here: the

module will be called ipv6.

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

Tunneling means encapsulating data of one protocol type within
|
|
another protocol and sending it over a channel that understands the
|
|
encapsulating protocol. This driver implements encapsulation of IPv6
|
|
into IPv4 packets. This is useful if you want to connect two IPv6
|
|
networks over an IPv4-only path.

Saying M here will produce a module called sit.ko. If unsure, say Y.

---help---
|

Enable routing by source address or prefix.
|
|
|
|
The destination address is still the primary routing key, so mixing
|
|
normal and source prefix specific routes in the same routing table
|
|
may sometimes lead to unintended routing behavior. This can be
|
|
avoided by defining different routing tables for the normal and
|
|
source prefix specific routes.
