+ ---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.
+
+ If unsure, say N.
