Currently, when a network goes into CONNECTED state, we call updateLinkProperties and then notifyIfacesChangedForNetworkStats. The latter is unnecessary, as there are exactly two cases: 1. networkAgent.linkProperties != null: updateLinkProperties will call notifyIfacesChangedForNetworkStats, because oldLp is null and networkAgent.linkProperties is not null. 2. networkAgent.linkProperties is null: there is no need to call notifyIfacesChangedForNetworkStats, because no interfaces were added or removed. When they are, updateLinkProperties will be called again. Removing the call to notifyIfacesChangedForNetworkStats avoids a stats poll, which is a minor performance improvement. Also, remove the NetworkStatsService code to do asynchronous interface updates, since it has no callers.
