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

  142. ---help---
  143. IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon
  144. mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly
  145. deploy IPv6 unicast service to IPv4 sites to which it provides
  146. customer premise equipment. Like 6to4, it utilizes stateless IPv6 in
  147. IPv4 encapsulation in order to transit IPv4-only network
  148. infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6
  149. prefix of its own in place of the fixed 6to4 prefix.
  150. With this option enabled, the SIT driver offers 6rd functionality by
  151. providing additional ioctl API to configure the IPv6 Prefix for in
  152. stead of static 2002::/16 for 6to4.

  175. normal and source prefix specific routes in the same routing table
  176. may sometimes lead to unintended routing behavior. This can be
