For L3 support, we had discussed this previously on the mailer, but
never came to a conclusion. I think this is a big challenge to tackle,
but would provide benefits to OVS, and certainly would benefit
LISP. We'll work on this infrastructure and propose something around

I think this can be addressed with future patches. For now, we've simply
enabled a very basic version of LISP.

This is the most interesting aspect, and is something we'll have more to
say about soon.

Well, ultimately having OVS be able to participate in a LISP network would
be the ideal end result. I think this is just a first step to getting us there.
