That won't help in the short term. I'm still reading up to see if
there are
any other options besides reimplement or advertise-but-drop, such as
an implicit trigger that would make the guest renegotiate. It's
unlikely, but
worth a look..

Yes, this looks hard. And even if we can manage to do this, it looks
an overkill since it will impact all guest after migration.

Like Willem I would much prefer "advertise-but-drop" if it works.

This makes migration work but all guest UFO traffic will stall.

The idea is that the sender will resend and it will be smaller and
thus non-UFO.
