Mirroring is provided through setting of sampling rate to 100% of the traff= ic. Motivation: Enable monitoring and statistics on classified traffic for busi= ness or lawful interception. Examples: Monitor hairpin traffic that does not reach the application; Mirr= or traffic for lawful interception use case; [2] Add rte_flow API for matching on frag/non-frag packets on both IPv4 and= IPv6 Support for Ipv4/6, TCP/UDP/ICMP fragmented and non-fragmented packet. Supported modes: No Fragment, First Fragment, Next Fragment. Motivation: Allow DPDK applications that are using frag modes (e.g. OVS-DPD= K) to define it through DPDK rte_flow API. [3] Add support for extension header in Geneve tunneling Support matching on Geneve options header - TLV and data. [4] Support Hairpin between different ports in NIC mode Extend current support from "hairpin in the same port" to "hairpin with a d= ifferent ports on the same NIC". Motivation: Provide better utilization of network resources (physical ports= ) and allow flexible alignment with security, network isolation and balanci= ng practices. rte_flow new APIs: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [5] Extend the DPDK flow action API to enable support of a shared rte_flow_= action context A modification of a single rte_flow_action context replaces the current app= roach which requires multiple modifications of (identical) flow actions. Motivation: When multiple flow rules such as RSS have the same action, this= action is cloned and used on each of the flows. Prior to the proposed chan= ge, any update to the RSS action (e.g. adding/removing queue) required reco= nfiguration of all the flows. This re-configuration is non-efficient, and t= he newly proposed APIs provide means to influence all the relevant flows th= rough a single change in the shared action context that is being used by al= l the relevant flows. [6] Allow synced rte_flow rule-management (create/destroy) Add capability to enforce synchronous rule insertion to simplify DPDK softw= are rule-management. functions in scope: rte_flow_create/destroy. [7] Add Connection Tracking (CT) abstraction layer for CT offloading Implementation logic is vendor-specific and thus shall be implemented in th= e PMD by each vendor. Motivation: Allow DPDK application (e.g. OVS-DPDK) to offload the Connectio= n Tracking logic to the NIC. [8] Add v-tunnel abstraction layer for tunnel offloading Implementation logic is vendor-specific and thus shall be implemented in th= e PMD by each vendor. Motivation: Allow DPDK application (e.g. OVS-DPDK) to do tunnel offloading. ethdev API update: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [9] Support buffer split to multiple destinations Provide means to split the buffer in the receive queue and send it to multi= ple destinations to be handled by CPU, GPU and potentially others. Motivation: Accelerate packet handling by sending the data directly to its = processor. mlx5 PMD updates: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [*] mlx5 PMD will support the rte_flow update changes listed above. Enhanced functionality: [10] Provide visibility on Rx queue status Extend current function (rx_descriptor_status(), rx_descriptor_count (imple= mentation to support vectorized and mprq modes) Motivation: Provides DPDK software with additional monitoring capabilities = of the Rx queue status. Performance improvement [11] Add mlx5 PMD use of vectorized instructions when using Striding RQ (MP= RQ) Motivation: Performance improvement and CPU cycles reduction [12] Added native DPDK support for multi-threaded rte_flow API Motivation: Allow rules insertions and deletions from multiple threads with= native sync/lock and inherent improved insertion rate. [13] Improve performance for aging mechanism, reduce memory consumption for= flow and CPU cycles for logic Motivation: Improve performance by reducing latency of counters reading whe= n such is not required [14] Improved PCIe performance with flow-tags [15] Improved PCIe performance with mixed protocols (TCP/UDP) New DPDK PMD for compression/decompression support: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [16] Implement look aside compression/decompression to support existing rte= _compress API Implementation for compress/decompress/dma actions testpmd updates: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [*] testpmd updated to support the changes listed above.
