This allows us to maintain NetworkStats entries that track whether the traffic was on the default network. At the moment, the stats collection code always passes in DEFAULT_NETWORK_NO. However, this value is a no-op, since it is not persisted to disk. Only the ident, the uid/set/tag, and the packet/byte/operation counters are persisted. A future change will add defaultNetwork to the ident and start persisting it. Bug: 35142602 Test: runtest frameworks-net Change-Id: Ifa291c62c0fa389b88e5561086a29dcd7cee2253
