Tokyo conclusion: with our answer to #2143, the endpoint that disables migration will have to do the full migration machinery.  If it doesn't do that work, then the server needs to drop the packet (thereby ignoring it).

Note that it can't send a stateless reset here, because that would produce the attack in a different form - our existing text on defense against stateless reset oracles would prohibit that anyway.

We should perhaps rename the transport parameter to "disable_explicit_migration" or "disable_active_migration".
