The link layer certainly has its own mechanisms, as does IP on
top of it (e.g. IPv6 NUD). But these are for a link, what we are
talking about here is a path through the Internet. More specifically,
the question is what to do if IKEv2 DPD tells us that its not getting
through. Should we (a) kill the connection or (b) switch to another
address we have? I think the latter...
