+         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.
