We're still working out the details of that mechanism, but the idea is that FaceManager maintains a mapping from NICs to faces. Andrea will post a more detailed design once we get there.

We've some design questions regarding permanent unicast faces, in particular how they behave when their face local address is removed from the interface. For example, when the permanent face local address is removed from the interface there could be the possibility to communicate with the face remote endpoint using a different local address. Is it the behavior we want for a permanent face?

Our proposed solution, that fits well our scenario, is to choose an address from the same interface when the face local address has been removed. If no other address is available the face will stick around until an address becomes available on that interface. Is this a good behavior for a permanent face? It could be strange if a user specify a local address when creating the permanent face(#3471).
