2. DPDK Release 18.08 2.1. New Features Added support for Hyper-V netvsc PMD. The new netvsc poll mode driver provides native support for networking on Hyper-V. See the Netvsc poll mode driver NIC driver guide for more details on this new driver. Added Flow API support for CXGBE PMD. Flow API support has been added to CXGBE Poll Mode Driver to offload flows to Chelsio T5/T6 NICs. Support added for: Wildcard (LE-TCAM) and Exact (HASH) match filters. Match items: physical ingress port, IPv4, IPv6, TCP and UDP. Action items: queue, drop, count, and physical egress port redirect. Added ixgbe preferred Rx/Tx parameters. Rather than applications providing explicit Rx and Tx parameters such as queue and burst sizes, they can request that the EAL instead uses preferred values provided by the PMD, falling back to defaults within the EAL if the PMD does not provide any. The provision of such tuned values now includes the ixgbe PMD. Added descriptor status check support for fm10k. The rte_eth_rx_descriptor_status and rte_eth_tx_descriptor_status APIs are now supported by fm10K. Updated the enic driver. Add low cycle count Tx handler for no-offload Tx. Add low cycle count Rx handler for non-scattered Rx. Minor performance improvements to scattered Rx handler. Add handlers to add/delete VxLAN port number. Add devarg to specify ingress VLAN rewrite mode. Updated mlx5 driver. Updated the mlx5 driver including the following changes: Added port representors support. Added Flow API support for e-switch rules. Added support for ACTION_PORT_ID, ACTION_DROP, ACTION_OF_POP_VLAN, ACTION_OF_PUSH_VLAN, ACTION_OF_SET_VLAN_VID, ACTION_OF_SET_VLAN_PCP and ITEM_PORT_ID. Added support for 32-bit compilation. Added TSO support for the mlx4 driver. Added TSO support for the mlx4 drivers from MLNX_OFED_4.4 and above. SoftNIC PMD rework. The SoftNIC PMD infrastructure has been restructured to use the Packet Framework, which makes it more flexible, modular and easier to add new functionality in the future. Updated the AESNI MB PMD. The AESNI MB PMD has been updated with additional support for: 3DES for 8, 16 and 24 byte keys. Added a new compression PMD using Intel’s QuickAssist (QAT) device family. Added the new QAT compression driver, for compression and decompression operations in software. See the Intel(R) QuickAssist (QAT) Compression Poll Mode Driver compression driver guide for details on this new driver. Updated the ISA-L PMD. Added support for chained mbufs (input and output).

TRex低成本，高速有状态流量生成器 TRex是有状态和无状态用例的流量生成器。 传统上，网络基础设施设备是使用商用流量生成器进行测试的，而性能是使用诸如每秒数据包（PPS）和无丢包率（NDR）之类的指标进行衡量的。 随着网络基础结构功能变得越来越复杂，有状态的流量生成器已变得很有必要，以便测试更实际的应用程序流量模式方案。 需要现实的和有状态的流量生成器，以便： 测试并提供更真实的性能数字 基于实际用例的软件和硬件的设计和架构 当前的挑战 费用：商业性全州交通产生器价格昂贵 缩放：带宽随着功能的复杂性无法很好地扩展 标准化：缺乏交通方式和方法的标准化 灵活性：当需要灵活性和更改时，商业工具不允许敏捷 含意 不同团队花费的高资本支出（capEx） 小规模测试和外推法已成为一种普遍做法，它不准确，并且掩盖了现实生活中的瓶颈和质量问题 不同的功能/平台团队基准测试和结果方法 由于测试工具
