With an extra interface it will allow to add both RtpRtcp module and RtcpTransceiver as feedback sender to PacketRouter Though hacky, this is very similar to currently used implementation in the RTCPSender::SendFeedbackPacket Bug: webrtc:8239 Change-Id: I237b422ae1594dede78cb63daa4aa42b6774d6fe Reviewed-on: https://webrtc-review.googlesource.com/32680 Commit-Queue: Danil Chapovalov <danilchap@webrtc.org> Reviewed-by: Niels Moller <nisse@webrtc.org> Cr-Commit-Position: refs/heads/master@{#21274}
