22 .. This section should contain new features added in this release. Sample format:
24 * **Add a title in the past tense with a full stop.**
26 Add a short 1-2 sentence description in the past tense. The description
27 should be enough to allow someone scanning the release notes to understand
30 If the feature adds a lot of sub-features you can use a bullet list like this.
32 * Added feature foo to do something.
33 * Enhanced feature bar to do something else.
35 Refer to the previous release notes for examples.

39 =========================================================
41 * **Added generic flow API (rte_flow).**
43 This API provides a generic means to configure hardware to match specific
44 ingress or egress traffic, alter its fate and query related counters
45 according to any number of user-defined rules.
47 It is slightly higher-level than the legacy filtering framework which it
48 encompasses and supersedes (including all functions and filter types) in
49 order to expose a single interface with an unambiguous behavior that is
50 common to all poll-mode drivers (PMDs).
52 See the :ref:`Generic flow API <Generic_flow_API>` documentation for more
55 * **Added firmware version get API.**
57 Added a new function ``rte_eth_dev_fw_version_get()`` to fetch firmware
58 version by a given device.
60 * **Added APIs for MACsec offload support to the ixgbe PMD.**
62 Six new APIs have been added to the ixgbe PMD for MACsec offload support.
63 The declarations for the APIs can be found in ``rte_pmd_ixgbe.h``.
65 * **Added I219 NICs support.**
67 Added support for I219 Intel 1GbE NICs.
69 * **Added Solarflare libefx-based network PMD.**
71 A new network PMD which supports Solarflare SFN7xxx and SFN8xxx family
72 of 10/40 Gbps adapters has been added.
74 * **Added support for Mellanox ConnectX-5 adapters (mlx5).**
76 Support for Mellanox ConnectX-5 family of 10/25/40/50/100 Gbps adapters
77 has been added to the existing mlx5 PMD.
79 * **virtio-user with vhost-kernel as another exceptional path.**
81 Previously, we upstreamed a virtual device, virtio-user with vhost-user
82 as the backend, as a way for IPC (Inter-Process Communication) and user
83 space container networking.
85 Virtio-user with vhost-kernel as the backend is a solution for exceptional
86 path, such as KNI, which exchanges packets with kernel networking stack.
87 This solution is very promising in:
89 * maintenance: vhost and vhost-net (kernel) is upstreamed and extensively
91 * features: vhost-net is born to be a networking solution, which has
92 lots of networking related features, like multi-queue, TSO, multi-seg
94 * performance: similar to KNI, this solution would use one or more
95 kthreads to send/receive packets from user space DPDK applications,
96 which has little impact on user space polling thread (except that
97 it might enter into kernel space to wake up those kthreads if
100 * **Added virtio Rx interrupt suppprt.**
102 This feature enables Rx interrupt mode for virtio pci net devices as
103 binded to VFIO (noiommu mode) and drived by virtio PMD.
105 With this feature, virtio PMD can switch between polling mode and
106 interrupt mode, to achieve best performance, and at the same time save
107 power. It can work on both legacy and modern virtio devices. At this mode,
108 each rxq is mapped with an exluded MSIx interrupt.
110 See the :ref:`Virtio Interrupt Mode <virtio_interrupt_mode>` documentation
111 for more information.
117 .. This section should contain bug fixes added to the relevant sections. Sample format:
119 * **code/section Fixed issue in the past tense with a full stop.**
121 Add a short 1-2 sentence description of the resolved issue in the past tense.
122 The title should contain the code/lib section like a commit message.

139 Fixed few regressions introduced in recent releases that break the virtio
140 multiple process support.

152 Querying a non-PCI device was dereferencing non-existent PCI data
153 resulting in a segmentation fault.

185 =========================================================
187 * **Moved five APIs for VF management from the ethdev to the ixgbe PMD.**
