+	  Support for IPv6 Identifier Locator Addressing (ILA).
+
+	  ILA is a mechanism to do network virtualization without
+	  encapsulation. The basic concept of ILA is that we split an
+	  IPv6 address into a 64 bit locator and 64 bit identifier. The
+	  identifier is the identity of an entity in communication
+	  ("who") and the locator expresses the location of the
+	  entity ("where").
+
+	  ILA can be configured using the "encap ila" option with
+	  "ip -6 route" command. ILA is described in
+	  https://tools.ietf.org/html/draft-herbert-nvo3-ila-00.
+

+	bool "IPv6: IPv6 Rapid Deployment (6RD)"
+	depends on IPV6_SIT
+	default n
+	help
+	  IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon
+	  mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly
+	  deploy IPv6 unicast service to IPv4 sites to which it provides
+	  customer premise equipment.  Like 6to4, it utilizes stateless IPv6 in
+	  IPv4 encapsulation in order to transit IPv4-only network
+	  infrastructure.  Unlike 6to4, a 6rd service provider uses an IPv6
+	  prefix of its own in place of the fixed 6to4 prefix.
+
+	  With this option enabled, the SIT driver offers 6rd functionality by
+	  providing additional ioctl API to configure the IPv6 Prefix for in
+	  stead of static 2002::/16 for 6to4.

+	depends on NET_IPGRE_DEMUX
+	help
+	  Tunneling means encapsulating data of one protocol type within
+	  another protocol and sending it over a channel that understands the
+	  encapsulating protocol. This particular tunneling driver implements
+	  GRE (Generic Routing Encapsulation) and at this time allows
+	  encapsulating of IPv4 or IPv6 over existing IPv6 infrastructure.
+	  This driver is useful if the other endpoint is a Cisco router: Cisco
+	  likes GRE much better than the other Linux tunneling driver ("IP
+	  tunneling" above). In addition, GRE allows multicast redistribution
+	  through the tunnel.
+

+	  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

+	  Normally, a multicast router runs a userspace daemon and decides
