dp-packet batches can hold only a fixed count of packets since their introduction.
This limitation makes it impossible to split packets/emit more than the batch size during the processing of one batch. This series proposes to dynamically grow those batches when a NETDEV_MAX_BURST threshold is reached. -- David Marchand Changes since v1: - added more AT_CHECK in unit tests, - enhanced readability (variable names, capacity helper introduction...), - fixed AF_XDP netdev transmission, Changes since RFC v1: - rebased, - with AVX512 removal, patch 2 was dropped and some other patches got simpler, - add some helper for ip fragments, - split patch 4 in multiple patches and refactored meter and output actions to drop the dependency on NETDEV_MAX_BURST arrays, - updated max retries count for vhost-user ports, David Marchand (14): tests: Add a helper to check coverage counters. tests: Add a helper for generating IP fragments. dpif-netdev: Remove ambiguous array size. dpif-netdev: Prepare metering for dynamic packet batches. dpif-netdev: Prepare recirculation for dynamic packet batches. dpif-netdev: Prepare output for dynamic packet batches. netdev-afxdp: Prepare for dynamic packet batches. netdev-dpdk: Prepare vhost transmission for dynamic packet batches. dp-packet: Prepare for dynamic packet batches. dp-packet: Introduce dynamic packet batches. dpif-netdev: Use dynamic packet batches for output. ipf: Use dynamic packet batches. dp-packet-gso: Use dynamic packet batches. netdev: Use software GSO for nested tunnels.
