These patches re-enable id, with some extra care: with autotuning enable/large send buffer we need a more accurate packet scheduler to be able to use efficiently the available subflow bandwidth, especially when the subflows have different capacities. The first patch cleans-up subflow socket handling, making the actual re-enable (patch 2) simpler. Patches 3 and 4 improve the packet scheduler, to better cope with non trivial scenarios and large send buffer. = Finally patch 5 adds and uses some infrastructure to avoid the workqueue usage for the packet scheduler operations introduced by the previous patches. Paolo Abeni (5): mptcp: always graft subflow socket to parent mptcp: re-enable sndbuf autotune mptcp: do not queue excessive data on subflows mptcp: schedule work for better snd subflow selection mptcp: implement delegated actions net/mptcp/protocol.c | 176 ++++++++++++++++++++++++++++--------------- net/mptcp/protocol.h | 72 ++++++++++++++++++ net/mptcp/subflow.c | 49 +++++++++++- 3 files changed, 234 insertions(+), 63 deletions(-) -- = 2.26.2 --===============0518966205494776181==--
