### Ztunnel Shutdown Requirements

Our high level requirement is to minimize traffic disruption.

However, because Ztunnel operates only at Layer 4, we are in a tricky position:
* TCP is stateful, so we cannot really just pass state over to the other process.
  If we operated at L3 we could just start processing packets in the new Ztunnel.
