The call to the query API returns immediately to free the CPU for other tasks. The Application can get the query results from rte_flow_pull() asynchronously. [3] Add direction info when creating the transfer table. https://patches.dpdk.org/project/dpdk/patch/20220811071315.851032-1-rongw...@nvidia.com/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpatches.dpdk.org%2Fproject%2Fdpdk%2Fpatch%2F20220811071315.851032-1-rongweil%40nvidia.com%2F&data=05%7C01%7Clmargalit%40nvidia.com%7C461f54315657470a9a9208da90c3e33d%7C43083d15727340c1b7db39efd9ccc17a%7C0%7C0%7C637981468244371938%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=q%2FOXEVEZ%2BdPGclRxNgqpXAWura0FMMvgYRvsaJwuL4Y%3D&reserved=0> Add option to define the transfer_mode (traffic originates from uplink/vport/both) when creating the HW table to reduce memory footprint. [4] Add send to kernel action https://patches.dpdk.org/project/dpdk/patch/20220811113544.1718643-1-michael...@nvidia.com/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpatches.dpdk.org%2Fproject%2Fdpdk%2Fpatch%2F20220811113544.1718643-1-michaelsav%40nvidia.com%2F&data=05%7C01%7Clmargalit%40nvidia.com%7C461f54315657470a9a9208da90c3e33d%7C43083d15727340c1b7db39efd9ccc17a%7C0%7C0%7C637981468244371938%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Ito5mGfiY%2BjPL2wsKL37bJt0rN0uK8Kyx19Oz7%2B3%2FT4%3D&reserved=0> Introduce new rte_flow action to route the packet to the kernel.

[6] Support GTP PSC QFI in modify_field flow action https://patches.dpdk.org/project/dpdk/patch/20220921101839.1711058-2-dsosnow...@nvidia.com/ Add RTE_FLOW_FIELD_GTP_PSC_QFI to enum rte_flow_field_id. [7] Extend indirect action update for AGE action Add a new structure for indirect AGE action update to support updating the timeout value and start, stop or restart the aging check. Net/mlx5 PMD updates: ==================== [1] Support for flow template API and asynchronous queue-based management. [2] Support port_representor match item Match traffic originated from specific port representor. Creating a rule with this match item will ensure that other representors are not affected. Testpmd updates: =============== [1] Support the changes in rte_flow listed above.
