Summary: second try of this diff, now after fixing the uninitizlied std::chrono::duration values in BBR and Copa No need to pass the minimal interval any more since everywhere we just pass the transportSettings value. Just that inside the function directly Reviewed By: oesh Differential Revision: D16985567 fbshipit-source-id: 3818371708633a324256e62b7f49bd6d1441e991
