Want support for DHCPv6 Reconfigure messages #844
Description
We're currently expanding IPv6 support for guests throughout the product. We haven't yet fully decided on the NAT stance for IPv6, though. That is, to guests see the public IPv6 address directly in the guest, or do we NAT it just like IPv4? If we eschew NAT, we need a way to notify the guest (not just OPTE) that a public address like a Floating IP has changed. The most viable path here is to have OPTE emit a DHCPv6 Reconfigure message, asking the client to renew its lease.
We shouldn't start this work until we make the decision to eschew NAT for IPv6, but I want to keep track of this until then.
