This section should contain new features added in this release. Sample format: * **Add a title in the past tense with a full stop.** Add a short 1-2 sentence description in the past tense. The description should be enough to allow someone scanning the release notes to understand the new feature. If the feature adds a lot of sub-features you can use a bullet list like this. * Added feature foo to do something. * Enhanced feature bar to do something else. Refer to the previous release notes for examples. This section is a comment. do not overwrite or remove it. Also, make sure to start the actual text at the margin. ========================================================= * **Added generic flow API (rte_flow).** This API provides a generic means to configure hardware to match specific ingress or egress traffic, alter its fate and query related counters according to any number of user-defined rules. It is slightly higher-level than the legacy filtering framework which it encompasses and supersedes (including all functions and filter types) in order to expose a single interface with an unambiguous behavior that is common to all poll-mode drivers (PMDs). See the :ref:`Generic flow API ` documentation for more information. * **Added firmware version get API.** Added a new function ``rte_eth_dev_fw_version_get()`` to fetch firmware version by a given device. * **Added APIs for MACsec offload support to the ixgbe PMD.** Six new APIs have been added to the ixgbe PMD for MACsec offload support. The declarations for the APIs can be found in ``rte_pmd_ixgbe.h``. * **Added I219 NICs support.** Added support for I219 Intel 1GbE NICs. * **Added VF Daemon (VFD) on i40e. - EXPERIMENTAL** This's an EXPERIMENTAL feature to enhance the capability of DPDK PF as many VF management features are not supported by kernel PF driver. Some new private APIs are implemented in PMD without abstrction layer. They can be used directly by some users who have the need. The new APIs to control VFs directly from PF include, 1) set VF MAC anti-spoofing 2) set VF VLAN anti-spoofing 3) set TX loopback 4) set VF unicast promiscuous mode 5) set VF multicast promiscuous mode 6) set VF MTU 7) get/reset VF stats 8) set VF MAC address 9) set VF VLAN stripping 10) VF VLAN insertion 12) set VF broadcast mode 13) set VF VLAN tag 14) set VF VLAN filter VFD also includes VF to PF mailbox message management by APP. When PF receives mailbox messages from VF, PF should call the callback provided by APP to know if they're permitted to be processed. As an EXPERIMENTAL feature, please aware it can be changed or even removed without prior notice. * **Updated the i40e base driver.** updated the i40e base driver, including the following changes: * replace existing legacy memcpy() calls with i40e_memcpy() calls. * use BIT() macro instead of bit fields * add clear all WoL filters implementation * add broadcast promiscuous control per VLAN * remove unused X722_SUPPORT and I40E_NDIS_SUPPORT MARCOs * **Added Solarflare libefx-based network PMD.** A new network PMD which supports Solarflare SFN7xxx and SFN8xxx family of 10/40 Gbps adapters has been added. * **Added support for Mellanox ConnectX-5 adapters (mlx5).** Support for Mellanox ConnectX-5 family of 10/25/40/50/100 Gbps adapters has been added to the existing mlx5 PMD. * **virtio-user with vhost-kernel as another exceptional path.** Previously, we upstreamed a virtual device, virtio-user with vhost-user as the backend, as a way for IPC (Inter-Process Communication) and user space container networking. Virtio-user with vhost-kernel as the backend is a solution for exceptional path, such as KNI, which exchanges packets with kernel networking stack. This solution is very promising in: * maintenance: vhost and vhost-net (kernel) is upstreamed and extensively used kernel module. * features: vhost-net is born to be a networking solution, which has lots of networking related features, like multi-queue, TSO, multi-seg mbuf, etc. * performance: similar to KNI, this solution would use one or more kthreads to send/receive packets from user space DPDK applications, which has little impact on user space polling thread (except that it might enter into kernel space to wake up those kthreads if necessary). * **Added virtio Rx interrupt suppprt.** This feature enables Rx interrupt mode for virtio pci net devices as binded to VFIO (noiommu mode) and drived by virtio PMD. With this feature, virtio PMD can switch between polling mode and interrupt mode, to achieve best performance, and at the same time save power. It can work on both legacy and modern virtio devices. At this mode, each rxq is mapped with an exluded MSIx interrupt. See the :ref:`Virtio Interrupt Mode ` documentation for more information. * **Updated the QAT PMD.** The QAT PMD was updated with additional support for: * DES algorithm. * Scatter-gather list (SGL) support. * **Updated the AESNI MB PMD.** * The Intel(R) Multi Buffer Crypto for IPsec library used in AESNI MB PMD has been moved to a new repository, in GitHub. * **Added Elastic Flow Distributor library (rte_efd).** This new library uses perfect hashing to determine a target/value for a given incoming flow key. It does not store the key itself for lookup operations, and therefore, lookup performance is not dependent on the key size. Also, the target/value can be any arbitrary value (8 bits by default). Finally, the storage requirement is much smaller than a hash-based flow table and therefore, it can better fit for CPU cache, being able to scale to millions of flow keys. See the :ref:`Elastic Flow Distributor Library ` documentation in the Programmers Guide document, for more information. Resolved Issues --------------- ..
