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 VF Daemon (VFD) on i40e. - EXPERIMENTAL**
71 This's an EXPERIMENTAL feature to enhance the capability of DPDK PF as many
72 VF management features are not supported by kernel PF driver.
73 Some new private APIs are implemented in PMD without abstrction layer.
74 They can be used directly by some users who have the need.
76 The new APIs to control VFs directly from PF include,
77 1) set VF MAC anti-spoofing
78 2) set VF VLAN anti-spoofing
80 4) set VF unicast promiscuous mode
81 5) set VF multicast promiscuous mode
85 9) set VF VLAN stripping
87 12) set VF broadcast mode
89 14) set VF VLAN filter
90 VFD also includes VF to PF mailbox message management by APP.
91 When PF receives mailbox messages from VF, PF should call the callback
92 provided by APP to know if they're permitted to be processed.
94 As an EXPERIMENTAL feature, please aware it can be changed or even
95 removed without prior notice.
97 * **Updated the i40e base driver.**
99 updated the i40e base driver, including the following changes:
101 * replace existing legacy memcpy() calls with i40e_memcpy() calls.
102 * use BIT() macro instead of bit fields
103 * add clear all WoL filters implementation
104 * add broadcast promiscuous control per VLAN
105 * remove unused X722_SUPPORT and I40E_NDIS_SUPPORT MARCOs
107 * **Added Solarflare libefx-based network PMD.**
109 A new network PMD which supports Solarflare SFN7xxx and SFN8xxx family
110 of 10/40 Gbps adapters has been added.
112 * **Added support for Mellanox ConnectX-5 adapters (mlx5).**
114 Support for Mellanox ConnectX-5 family of 10/25/40/50/100 Gbps adapters
115 has been added to the existing mlx5 PMD.
117 * **virtio-user with vhost-kernel as another exceptional path.**
119 Previously, we upstreamed a virtual device, virtio-user with vhost-user
120 as the backend, as a way for IPC (Inter-Process Communication) and user
121 space container networking.
123 Virtio-user with vhost-kernel as the backend is a solution for exceptional
124 path, such as KNI, which exchanges packets with kernel networking stack.
125 This solution is very promising in:
127 * maintenance: vhost and vhost-net (kernel) is upstreamed and extensively
129 * features: vhost-net is born to be a networking solution, which has
130 lots of networking related features, like multi-queue, TSO, multi-seg
132 * performance: similar to KNI, this solution would use one or more
133 kthreads to send/receive packets from user space DPDK applications,
134 which has little impact on user space polling thread (except that
135 it might enter into kernel space to wake up those kthreads if
138 * **Added virtio Rx interrupt suppprt.**
140 This feature enables Rx interrupt mode for virtio pci net devices as
141 binded to VFIO (noiommu mode) and drived by virtio PMD.
143 With this feature, virtio PMD can switch between polling mode and
144 interrupt mode, to achieve best performance, and at the same time save
145 power. It can work on both legacy and modern virtio devices. At this mode,
146 each rxq is mapped with an exluded MSIx interrupt.
148 See the :ref:`Virtio Interrupt Mode <virtio_interrupt_mode>` documentation
149 for more information.
151 * **Added ARMv8 crypto PMD.**
153 A new crypto PMD has been added, which provides combined mode cryptografic
154 operations optimized for ARMv8 processors. The driver can be used to enhance
155 performance in processing chained operations such as cipher + HMAC.
157 * **Updated the QAT PMD.**
159 The QAT PMD was updated with additional support for:
162 * Scatter-gather list (SGL) support.
164 * **Updated the AESNI MB PMD.**
166 * The Intel(R) Multi Buffer Crypto for IPsec library used in
167 AESNI MB PMD has been moved to a new repository, in GitHub.
168 * Support for single operations (cipher only and authentication only).
170 * **Updated the AES-NI GCM PMD.**
172 The AES-NI GCM PMD was migrated from MB library to ISA-L library.
173 The migration entailed the following additional support for:
176 * 256-bit cipher key.
178 * Out-of place processing
179 * Scatter-gatter support for chained mbufs (only out-of place and destination
180 mbuf must be contiguous)
182 * **Added Elastic Flow Distributor library (rte_efd).**
184 This new library uses perfect hashing to determine a target/value for a
185 given incoming flow key.
187 It does not store the key itself for lookup operations, and therefore,
188 lookup performance is not dependent on the key size. Also, the target/value
189 can be any arbitrary value (8 bits by default). Finally, the storage requirement
190 is much smaller than a hash-based flow table and therefore, it can better fit for
191 CPU cache, being able to scale to millions of flow keys.
193 See the :ref:`Elastic Flow Distributor Library <Efd_Library>` documentation in
194 the Programmers Guide document, for more information.
