  "message": "DualPi2: Fix L4S double marking and backlog guard\n\nAligns DualPi2NetworkQueue marking and dropping behavior with RFC 9332\nand Linux sch_dualpi2 (!drop_early):\n\n1. Single L4S marking on dequeue: Previously, ShouldTakeAction() rolled\n   the random PI2 marking probability for ECT(1) packets in both\n   EnqueuePacket() and DequeuePacket(), resulting in an effective\n   marking probability of 2*p - p^2 instead of p. L4S packets are now\n   only evaluated for marking on dequeue.\n2. Time-based step_threshold: Replaces the byte-based step_threshold_\n   (which required Config::link_rate to be set and dropped classic\n   packets on enqueue) with Config::step_threshold as a TimeDelta\n   (defaulting to PlusInfinity) checked against L4S packet sojourn time\n   on dequeue.\n3. Standing-queue backlog guard: Adds Config::min_backlog_packets\n   (defaulting to 2) so that small 1-packet bursts are not marked or\n   dropped when there is no standing queue backlog.\n\nBug: webrtc:447037083, webrtc:42225697\nChange-Id: I2f75a159f895c6b994e2665ce9f77d0fb6f6cb45\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/508160\nReviewed-by: Rasmus Brandt \u003cbrandtr@webrtc.org\u003e\nCommit-Queue: Per Kjellander \u003cperkj@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#48841}\n",
