Today: you don't. The host can't change its behavior when the TCP
session has been established anyway.

Future: when it becomes possible for a host to jump from one set of
addresses to another (as in SCTP) it certainly becomes useful to do
this. The crude way: drop packets, the host will get the hint. The nice
way could be an ICMP message.
