29 * **Add a title in the past tense with a full stop.**
31 Add a short 1-2 sentence description in the past tense.
32 The description should be enough to allow someone scanning
33 the release notes to understand the new feature.
35 If the feature adds a lot of sub-features you can use a bullet list
38 * Added feature foo to do something.
39 * Enhanced feature bar to do something else.
41 Refer to the previous release notes for examples.
43 Suggested order in release notes items:
44 * Core libs (EAL, mempool, ring, mbuf, buses)
45 * Device abstraction libs and PMDs
47 - cryptodev (lib, PMDs)
48 - eventdev (lib, PMDs)
51 * Apps, Examples, Tools (if significant)

55 =========================================================
57 * **Updated the EAL Pseudo-random Number Generator.**
59 The lrand48()-based rte_rand() function is replaced with a
60 DPDK-native combined Linear Feedback Shift Register (LFSR)
61 pseudo-random number generator (PRNG).
63 This new PRNG implementation is multi-thread safe, provides
64 higher-quality pseudo-random numbers (including full 64 bit
65 support) and improved performance.
67 In addition, <rte_random.h> is extended with a new function
68 rte_rand_max() which supplies unbiased, bounded pseudo-random
71 * **Updated the bnxt PMD.**
73 Updated the bnxt PMD. The major enhancements include:
75 * Performance optimizations in non-vector Tx path
76 * Added support for SSE vector mode
77 * Updated HWRM API to version 1.10.0.74
79 * **Added support for Broadcom NetXtreme-E BCM57500 Ethernet controllers.**
81 Added support to the bnxt PMD for the BCM57500 (a.k.a. "Thor") family
82 of Ethernet controllers. These controllers support link speeds up to
83 200Gbps, 50G PAM-4, and PCIe 4.0.
85 * **Added hinic PMD.**
87 Added the new ``hinic`` net driver for Huawei Intelligent PCIE Network
88 Adapters based on the Huawei Ethernet Controller Hi1822.
89 See the :doc:`../nics/hinic` guide for more details on this new driver.
91 * **Updated the ice driver.**
93 Updated ice driver with new features and improvements, including:
95 * Enabled Tx outer/inner L3/L4 checksum offload.
97 * **Updated Solarflare network PMD.**
99 Updated the Solarflare ``sfc_efx`` driver with changes including:
101 * Added support for Rx interrupts.
103 * **Added memif PMD.**
105 Added the new Shared Memory Packet Interface (``memif``) PMD.
106 See the :doc:`../nics/memif` guide for more details on this new driver.
108 * **Updated the AF_XDP PMD.**
110 Updated the AF_XDP PMD. The new features include:
112 * Enabled zero copy through mbuf's external memory mechanism to achieve
114 * Added multi-queue support to allow one af_xdp vdev with multiple netdev
117 * **Updated telemetry library for global metrics support.**
119 Updated ``librte_telemetry`` to fetch the global metrics from the
120 ``librte_metrics`` library.
122 * **Added new telemetry mode for l3fwd-power application.**
124 Added telemetry mode to l3fwd-power application to report
125 application level busyness, empty and full polls of rte_eth_rx_burst().
