This is used by the VPN to notice when its underlying connection has gone away. I'm fixing this using network types and not NetworkCapabilities because 1. I don't know of a way to use the new API to get callbacks for a specific network. You can get them based on capabilities, but it's not clear how to construct a NetworkCapabilities object that will only match a specific network, or only match the default network. 2. It's a smaller change. Bug: 15070628 Change-Id: Id6a6a183da83636c0859db4c954093bd684c01ea
