DPDK Release 19.08
==================
Also, make sure to start the actual text at the margin.
=========================================================
+* **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 bnxt PMD.**
Updated the bnxt PMD. The major enhancements include:
of Ethernet controllers. These controllers support link speeds up to
200Gbps, 50G PAM-4, and PCIe 4.0.
+* **Added hinic PMD.**
+
+ Added the new ``hinic`` net driver for Huawei Intelligent PCIE Network
+ Adapters based on the Huawei Ethernet Controller Hi1822.
+ See the :doc:`../nics/hinic` guide for more details on this new driver.
+
+* **Updated the ice driver.**
+
+ Updated ice driver with new features and improvements, including:
+
+ * Enabled Tx outer/inner L3/L4 checksum offload.
+ * Enabled generic filter framework and supported switch filter.
+ * Supported UDP tunnel port add.
+
+* **Updated Mellanox mlx5 driver.**
+
+ Updated Mellanox mlx5 driver with new features and improvements, including:
+
+ * Updated the packet header modification feature. Added support of TCP header
+ sequence number and acknowledgment number modification.
+
+* **Updated Solarflare network PMD.**
+
+ Updated the Solarflare ``sfc_efx`` driver with changes including:
+
+ * Added support for Rx interrupts.
+
* **Added memif PMD.**
Added the new Shared Memory Packet Interface (``memif``) PMD.
See the :doc:`../nics/memif` guide for more details on this new driver.
+* **Updated the AF_XDP PMD.**
+
+ Updated the AF_XDP PMD. The new features include:
+
+ * Enabled zero copy through mbuf's external memory mechanism to achieve
+ high 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 case
+ that application and driver executing on the same core.
+
+* **Enabled infinite Rx in the PCAP PMD.**
+
+ Added an infinite Rx feature which allows packets in the Rx PCAP of a PCAP
+ device to be received repeatedly at a high rate. This can be useful for quick
+ performance testing of DPDK apps.
+
+* **Added Intel QuickData Technology PMD**
+
+ The PMD for Intel\ |reg| QuickData Technology, part of
+ Intel\ |reg| I/O Acceleration Technology `(Intel I/OAT)
+ <https://www.intel.com/content/www/us/en/wireless-network/accel-technology.html>`_,
+ allows data copies to be done by hardware instead
+ of via software, reducing cycles spent copying large blocks of data in
+ applications.
+
+* **Introduced NTB PMD.**
+
+ Added a PMD for Intel NTB (Non-transparent Bridge). This PMD implemented
+ handshake between two separate hosts and can share local memory for peer
+ host to directly access.
+
+* **Updated telemetry library for global metrics support.**
+
+ Updated ``librte_telemetry`` to fetch the global metrics from the
+ ``librte_metrics`` library.
+
+* **Added new telemetry mode for l3fwd-power application.**
+
+ Added telemetry mode to l3fwd-power application to report
+ application level busyness, empty and full polls of rte_eth_rx_burst().
+
Removed Items
-------------
Also, make sure to start the actual text at the margin.
=========================================================
+* The ``rte_mem_config`` structure has been made private. The 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
+ is deprecated and will be removed in a future release.
+
+* 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.
+
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.
