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. ==================== Link: https://lore.kernel.org/r/cover.1611153172.git.pabeni@redhat.com Signed-off-by: Jakub Kicinski --- 07fe179e5d8555a5d5e06b43bcf3ceac06b8f943
