DPDK Release 19.08
==================
Also, make sure to start the actual text at the margin.
=========================================================
+* **EAL will now pick IOVA as VA mode as the default in most cases.**
+
+ Previously, the preferred default IOVA mode was selected to be IOVA as PA. The
+ behavior has now been changed to handle IOVA mode detection in a more complex
+ manner, and will default to IOVA as VA in most cases.
+
+* **Added MCS lock.**
+
+ MCS lock provides scalability by spinning on a CPU/thread local variable
+ which avoids expensive cache bouncing.
+ It provides fairness by maintaining a list of acquirers and passing
+ the lock to each CPU/thread in the order they acquired the lock.
+
+* **Updated the EAL Pseudo-random Number Generator.**
+
+ The ``lrand48()`` based ``rte_rand()`` function is replaced with a
+ DPDK-native combined Linear Feedback Shift Register (LFSR)
+ pseudo-random number generator (PRNG).
+
+ This new PRNG implementation is multi-thread safe, provides
+ higher-quality pseudo-random numbers (including full 64 bit
+ support) and improved performance.
+
+ In addition, ``<rte_random.h>`` is extended with a new function
+ ``rte_rand_max()`` which supplies unbiased, bounded pseudo-random
+ numbers.
+
+* **Updated the Broadcom bnxt PMD.**
+
+ Updated the Broadcom bnxt PMD. The major enhancements include:
+
+ * Performance optimizations in non-vector Tx path.

+
+* **Added support for Broadcom NetXtreme-E BCM57500 Ethernet controllers.**
+
+ Added support to the Broadcom bnxt PMD for the BCM57500 (a.k.a. "Thor") family
+ of Ethernet controllers. These controllers support link speeds up to
+ 200Gbps, 50G PAM-4, and PCIe 4.0.
+
+* **Added Huawei hinic PMD.**

+
+ * Enabled zero copy through mbuf's external memory mechanism to achieve
+ higher performance.
+ * Added multi-queue support to allow one af_xdp vdev with multiple netdev
+ queues.
+ * Enabled "need_wakeup" feature which can provide efficient support for the
+ usecase where the application and driver executing on the same core.
+
+* **Enabled infinite Rx in the PCAP PMD.**
+
+ Added an infinite Rx feature to the PCAP PMD which allows packets in the Rx
+ PCAP to be received repeatedly at a high rate. This can be useful for quick
+ performance testing of DPDK apps.
+
+* **Enabled receiving no packet in the PCAP PMD.**
+
+ Added function to allow users to run the PCAP PMD without receiving any
+ packets on PCAP Rx. When the function is called, a dummy queue is created
+ for each Tx queue argument passed.

Removed Items
-------------
Also, make sure to start the actual text at the margin.
=========================================================
+* Removed KNI ethtool, ``CONFIG_RTE_KNI_KMOD_ETHTOOL``, support.
+
+* build: armv8 crypto extension is disabled.
+
API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* The ``rte_mem_config`` structure has been made private. New accessor
+ ``rte_mcfg_*`` functions were introduced to provide replacement for direct
+ access to the shared mem config.
+
* The network structures, definitions and functions have
been prefixed by ``rte_`` to resolve conflicts with libc headers.
+* malloc: The function ``rte_malloc_set_limit()`` was never implemented.
+ It is deprecated and will be removed in a future release.
+
+* cryptodev: the ``uint8_t *data`` member of the ``key`` structure in the xforms
+ structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and
+ ``rte_crypto_aead_xform``) have been changed to ``const uint8_t *data``.
+
+* eventdev: No longer marked as experimental.
+
+ The eventdev functions are no longer marked as experimental, and have
+ become part of the normal DPDK API and ABI. Any future ABI changes will be
+ announced at least one release before the ABI change is made. There are no
+ ABI breaking changes planned.
+
+* ip_frag: The IP fragmentation library converts input mbuf into fragments
+ using input MTU size via the ``rte_ipv4_fragment_packet()`` interface.
+ Once fragmentation is done, each ``mbuf->ol_flags`` are set to enable IP
+ checksum H/W offload irrespective of the platform capability.
+ Cleared IP checksum H/W offload flag from the library. The application must
+ set this flag if it is supported by the platform and application wishes to
+ use it.
+
+* ip_frag: IP reassembly library converts the list of fragments into a
+ reassembled packet via ``rte_ipv4_frag_reassemble_packet()`` interface.
+ Once reassembly is done, ``mbuf->ol_flags`` are set to enable IP checksum H/W
+ offload irrespective of the platform capability. Cleared IP checksum H/W
+ offload flag from the library. The application must set this flag if it is
+ supported by the platform and application wishes to use it.
+
+* sched: Macros ``RTE_SCHED_QUEUES_PER_TRAFFIC_CLASS`` and
+ ``RTE_SCHED_PIPE_PROFILES_PER_PORT`` are removed for flexible configuration
+ of pipe traffic classes and their queues size, and for runtime configuration
+ of the maximum number of pipe profiles, respectively. In addition, the
+ ``wrr_weights`` field of struct ``rte_sched_pipe_params`` is modified to be
+ used only for best-effort tc, and the ``qsize`` field of struct
+ ``rte_sched_port_params`` is changed to allow different sizes for each
+ queue.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eventdev: Event based Rx adapter callback
+
+ The mbuf pointer array in the event eth Rx adapter callback
+ has been replaced with an event array. Using
+ an event array allows the application to change attributes
+ of the events enqueued by the SW adapter.
+
+ The callback can drop packets and populate
+ a callback argument with the number of dropped packets.
+ Add a Rx adapter stats field to keep track of the total
+ number of dropped packets.
+
+* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
+ disable features supported by the crypto device. Only the following features
+ would be allowed to be disabled this way,
+
+ - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``.
+ - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``.
+ - ``RTE_CRYPTODEV_FF_SECURITY``.
+
+ Disabling unused features would facilitate efficient usage of HW/SW offload.
+
+* bbdev: New operations and parameters have been added to support new 5GNR
+ operations. The bbdev ABI is still kept experimental.
+
+* rawdev: The driver names have been changed to ``librte_rawdev_*``.
+ Now they all have the same prefix, and same name with make and meson builds.

=========================================================
+* **Unsuitable IOVA mode may be picked as the default.**
+
+ Not all kernel drivers and not all devices support all IOVA modes. EAL will
+ attempt to pick a reasonable default based on a number of factors, but
+ there may be cases where the default is unsuitable.
+
+ It is recommended to use the `--iova-mode` command-line parameter if the
+ default is not suitable.
