Currently we use the NetworkStatistics to monitor these metrics, but because these get reset on every call, this makes it impossible to use them for other purposes. Bug: webrtc:9667 Change-Id: If648085f04d2d58aae263cff5b9491bcad373a96 Reviewed-on: https://webrtc-review.googlesource.com/99740 Reviewed-by: Henrik Lundin <henrik.lundin@webrtc.org> Commit-Queue: Ivo Creusen <ivoc@webrtc.org> Cr-Commit-Position: refs/heads/master@{#24727}
