The kernel does everything that's needed to setup your ipv6 addresses. The
Link-local address is generated from your ethernet mac and the necessary
duplicate detection is done. The same goes  for the global address as soon as
you receive a router advertisement. The only thing userspace has to do is to
setup nameserver information basically.

Don't make a big deal out of everything; just deal with everything.
