=========================================================
+* **Added bucket mempool driver.**
+
+ Added bucket mempool driver which provides a way to allocate contiguous
+ block of objects.
+ Number of objects in the block depends on how many objects fit in
+ RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB memory chunk which is build time option.
+ The number may be obtained using rte_mempool_ops_get_info() API.
+ Contiguous blocks may be allocated using rte_mempool_get_contig_blocks() API.
+
* **Added PMD-recommended Tx and Rx parameters**
Applications can now query drivers for device-tuned values of
The ARM CPU subsystem features eight ARMv8 Cortex-A72 CPUs at 3.0 GHz, arranged in a multi-cluster
configuration.
+* **Added IFCVF vDPA driver.**
+
+ Added IFCVF vDPA driver to support Intel FPGA 100G VF device. IFCVF works
+ as a HW vhost data path accelerator, it supports live migration and is
+ compatible with virtio 0.95 and 1.0. This driver registers ifcvf vDPA driver
+ to vhost lib, when virtio connected, with the help of the registered vDPA
+ driver the assigned VF gets configured to Rx/Tx directly to VM's virtio
+ vrings.
+
* **Added support for virtio-user server mode.**
In a container environment if the vhost-user backend restarts, there's no way
for it to reconnect to virtio-user. To address this, support for server mode
including session creation/deletion handling and translating virtio-crypto
request into DPDK crypto operations. A sample application is also introduced.
+* **Added virtio crypto PMD.**
+
+ Added a new poll mode driver for virtio crypto devices, which provides
+ AES-CBC ciphering and AES-CBC with HMAC-SHA1 algorithm-chaining. See the
+ :doc:`../cryptodevs/virtio` crypto driver guide for more details on
+ this new driver.
+
+* **Added AMD CCP Crypto PMD.**
+
+ Added the new ``ccp`` crypto driver for AMD CCP devices. See the
+ :doc:`../cryptodevs/ccp` crypto driver guide for more details on
+ this new driver.
+
* **Updated AESNI MB PMD.**
The AESNI MB PMD has been updated with additional support for:
Linux uevent is supported as backend of this device event notification framework.
+* **Added support for procinfo and pdump on eth vdev.**
+
+ For ethernet virtual devices (like tap, pcap, etc), with this feature, we can get
+ stats/xstats on shared memory from secondary process, and also pdump packets on
+ those virtual devices.

API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* service cores: no longer marked as experimental.
+
+ The service cores 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.
+
+* eal: ``rte_lcore_has_role()`` return value changed.
+
+ This function now returns true or false, respectively,
+ rather than 0 or <0 for success or failure.
+ It makes use of the function more intuitive.
+
+* mempool: capability flags and related functions have been removed.
+
+ Flags ``MEMPOOL_F_CAPA_PHYS_CONTIG`` and
+ ``MEMPOOL_F_CAPA_BLK_ALIGNED_OBJECTS`` were used by octeontx mempool
+ driver to customize generic mempool library behaviour.
+ Now the new driver callbacks ``calc_mem_size`` and ``populate`` may be
+ used to achieve it without specific knowledge in the generic code.
+
+* mempool: xmem functions have been deprecated:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+ - ``rte_mempool_populate_iova_tab``
+
* mbuf: The control mbuf API has been removed in v18.05. The impacted
functions and macros are:
fall-back value. Previously, setting ``nb_tx_desc`` to zero would have
resulted in an error.
+* ethdev: several changes were made to the flow API.
+
+ * Unused DUP action was removed.
+ * Actions semantics in flow rules: list order now matters ("first
+ to last" instead of "all simultaneously"), repeated actions are now
+ all performed, and they do not individually have (non-)terminating
+ properties anymore.
+ * Flow rules are now always terminating unless a PASSTHRU action is
+ present.
+ * C99-style flexible arrays were replaced with standard pointers in RSS
+ action and in RAW pattern item structures due to compatibility issues.
+ * The RSS action was modified to not rely on external
+ ``struct rte_eth_rss_conf`` anymore to instead expose its own and more
+ appropriately named configuration fields directly
+ (``rss_conf->rss_key`` => ``key``,
+ ``rss_conf->rss_key_len`` => ``key_len``,
+ ``rss_conf->rss_hf`` => ``types``,
+ ``num`` => ``queue_num``), and the addition of missing RSS parameters
+ (``func`` for RSS hash function to apply and ``level`` for the
+ encapsulation level).
+ * The VLAN pattern item (``struct rte_flow_item_vlan``) was modified to
+ include inner EtherType instead of outer TPID. Its default mask was also
+ modified to cover the VID part (lower 12 bits) of TCI only.
+ * A new transfer attribute was added to ``struct rte_flow_attr`` in order
+ to clarify the behavior of some pattern items.
+ * PF and VF pattern items are now only accepted by PMDs that implement
+ them (bnxt and i40e) when the transfer attribute is also present for
+ consistency.
+ * Pattern item PORT was renamed PHY_PORT to avoid confusion with DPDK port
+ IDs.
+ * An action counterpart to the PHY_PORT pattern item was added in order to
+ redirect matching traffic to a specific physical port.
+ * PORT_ID pattern item and actions were added to match and target DPDK
+ port IDs at a higher level than PHY_PORT.
+
ABI Changes
-----------
structure and the offset of the fields remains the same on platforms
with 64B cache line, but change on other platforms.
+* mempool: ops have changed.
+
+ A new callback ``calc_mem_size`` has been added to ``rte_mempool_ops``
+ to allow to customize required memory size calculation.
+ A new callback ``populate`` has been added to ``rte_mempool_ops``
+ to allow to customize objects population.
+ Callback ``get_capabilities`` has been removed from ``rte_mempool_ops``
+ since its features are covered by ``calc_mem_size`` and ``populate``
+ callbacks.
+ Callback ``register_memory_area`` has been removed from ``rte_mempool_ops``
+ since the new callback ``populate`` may be used instead of it.
+
* **Additional fields in rte_eth_dev_info.**
The ``rte_eth_dev_info`` structure has had two extra entries appended to the
type ``uint16_t``: ``burst_size``, ``ring_size``, and ``nb_queues``. These
are parameter values recommended for use by the PMD.
+* ethdev: ABI for all flow API functions was updated.
+
+ This includes functions ``rte_flow_copy``, ``rte_flow_create``,
+ ``rte_flow_destroy``, ``rte_flow_error_set``, ``rte_flow_flush``,
+ ``rte_flow_isolate``, ``rte_flow_query`` and ``rte_flow_validate``, due to
+ changes in error type definitions (``enum rte_flow_error_type``), removal
+ of the unused DUP action (``enum rte_flow_action_type``), modified
+ behavior for flow rule actions (see API changes), removal of C99 flexible
+ array from RAW pattern item (``struct rte_flow_item_raw``), complete
+ rework of the RSS action definition (``struct rte_flow_action_rss``),
+ sanity fix in the VLAN pattern item (``struct rte_flow_item_vlan``) and
+ new transfer attribute (``struct rte_flow_attr``).
