Details:

This patch is just a first step to accept RDNSS RA options.

It works and configures dns servers via dns_setserver after receiving RA with
RDNSS option.

In the RFC 6106, there is defined Lifetime of the DNS server. This lifetime is
not handled fully by this patch. There can be different lifetimes per each DNS
server.

It is not a question how, but where to implement the lifetime. In nd6.c? In
dns.c? 

Before lifetime timeout, RS can be send to renew this option. This is also not
part of this patch.
