Upstream commit: https://webrtc.googlesource.com/src/+/776866774fd739996b60a6b683f7aa9fa3addd65 Propagate desicion if RTP packet should be ECT(1) marked to socket With this CL, the decision if an RTP packet should be sent as ect(1) is made in RtpControllerSend depending on if RFC 8888 has been negotiated and if CCFB is received with ECN enabled. Since webrtc does not yet adapt to ECN feedback, packets are sent as ECT(1) until the first feedback is received.
