27 .. This section should contain new features added in this release.
30 * **Add a title in the past tense with a full stop.**
32 Add a short 1-2 sentence description in the past tense.
33 The description should be enough to allow someone scanning
34 the release notes to understand the new feature.
36 If the feature adds a lot of sub-features you can use a bullet list
39 * Added feature foo to do something.
40 * Enhanced feature bar to do something else.
42 Refer to the previous release notes for examples.
44 Suggested order in release notes items:
45 * Core libs (EAL, mempool, ring, mbuf, buses)
46 * Device abstraction libs and PMDs (ordered alphabetically by vendor name)
48 - cryptodev (lib, PMDs)
49 - eventdev (lib, PMDs)
52 * Apps, Examples, Tools (if significant)

56 =======================================================
58 * **Added ability to reuse hugepages in Linux.**
60 It is possible to reuse files in hugetlbfs to speed up hugepage mapping,
61 which may be useful for fast restart and large allocations.
62 The new mode is activated with ``--huge-unlink=never``
63 and has security implications, refer to the user and programmer guides.
65 * **Added functions to calculate UDP/TCP checksum in mbuf.**
67 * Added the following functions to calculate UDP/TCP checksum of packets
68 which can be over multi-segments:
69 - ``rte_ipv4_udptcp_cksum_mbuf()``
70 - ``rte_ipv4_udptcp_cksum_mbuf_verify()``
71 - ``rte_ipv6_udptcp_cksum_mbuf()``
72 - ``rte_ipv6_udptcp_cksum_mbuf_verify()``
74 * **Added new RSS offload types for L2TPv2 in RSS flow.**
76 Added macro RTE_ETH_RSS_L2TPV2, now L2TPv2 session ID field can be used as
79 * **Added IP reassembly Ethernet offload API, to get and set config.**
81 Added IP reassembly offload APIs which provide functions to query IP
82 reassembly capabilities, to set configuration and to get currently set
83 reassembly configuration.
85 * **Added an API to enable queue based priority flow ctrl(PFC).**
87 New APIs, ``rte_eth_dev_priority_flow_ctrl_queue_info_get()`` and
88 ``rte_eth_dev_priority_flow_ctrl_queue_configure()``, was added.
90 * **Added a private dump API, to dump private info from device.**
92 Added the private dump API which provides querying private info from device.
93 There exists many private properties in different PMD drivers.
94 The information of these properties is important for debug.
95 As the information is private, a dump function is introduced.
97 * **Updated AF_XDP PMD**
99 * Added support for libxdp >=v1.2.2.
101 * **Updated Cisco enic driver.**
103 * Added rte_flow support for matching GENEVE packets.
104 * Added rte_flow support for matching eCPRI packets.
106 * **Updated Marvell cnxk crypto PMD.**
108 * Added SHA256-HMAC support in lookaside protocol (IPsec) for CN10K.
109 * Added SHA384-HMAC support in lookaside protocol (IPsec) for CN9K & CN10K.
110 * Added SHA512-HMAC support in lookaside protocol (IPsec) for CN9K & CN10K.
111 * Added AES-CTR support in lookaside protocol (IPsec) for CN9K & CN10K.
112 * Added NULL cipher support in lookaside protocol (IPsec) for CN9K & CN10K.
113 * Added AES-XCBC support in lookaside protocol (IPsec) for CN9K & CN10K.
114 * Added AES-CMAC support in CN9K & CN10K.
116 * **Added an API to retrieve event port id of ethdev Rx adapter.**
118 The new API ``rte_event_eth_rx_adapter_event_port_get()`` was added.
120 * **Updated testpmd.**
122 * Called ``rte_ipv4/6_udptcp_cksum_mbuf()`` functions in testpmd csum mode
123 to support software UDP/TCP checksum over multiple segments.
