The lock-free stack implementation is enabled for aarch64 platforms.
+* **Changed mempool allocation behaviour.**
+
+ Objects are no longer across pages by default.
+ It may consume more memory when using small memory pages.
+
* **Added support of dynamic fields and flags in mbuf.**
This new feature adds the ability to dynamically register some room
for specific offload features, where adding a static field or flag
in the mbuf is not justified.
+* **Added hairpin queue.**
+
+ On supported NICs, we can now setup haipin queue which will offload packets
+ from the wire, backto the wire.
+
+* **Added flow tag in rte_flow.**
+
+ SET_TAG action and TAG item have been added to support transient flow tag.
+
+* **Extended metadata support in rte_flow.**
+
+ Flow metadata is extended to both Rx and Tx.
+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to host via a dynamic field of ``rte_mbuf`` with
+ PKT_RX_DYNF_METADATA.
+
* **Updated the enic driver.**
* Added support for Geneve with options offload.
``rte_eth_tx_burst_mode_get`` that allow an application
to retrieve the mode information about RX/TX packet burst
such as Scalar or Vector, and Vector technology like AVX2.
- Another new function ``rte_eth_burst_mode_option_name`` is
- provided for burst mode options stringification.
* **Updated the Intel ice driver.**
* Added support for VLAN set PCP offload command.
* Added support for VLAN set VID offload command.
* Added support for matching on packets withe Geneve tunnel header.
+ * Added hairpin support.
* **Updated the AF_XDP PMD.**
* **Updated the IPSec library.**
- Added SA Database API to ``librte_ipsec``. A new test-sad application is also
- introduced to evaluate and perform custom functional and performance tests
- for IPsec SAD implementation.
+ * Added SA Database API to ``librte_ipsec``. A new test-sad application is also
+ introduced to evaluate and perform custom functional and performance tests
+ for IPsec SAD implementation.
+
+ * Support fragmented packets in inline crypto processing mode with fallback
+ ``lookaside-none`` session. Corresponding changes are also added in IPsec
+ Security Gateway application.
* **Introduced FIFO for NTB PMD.**
Added eBPF JIT support for arm64 architecture to improve the eBPF program
performance.
+* **Added RIB and FIB (Routing/Forwarding Information Base) libraries.**
+
+ RIB and FIB can replace the LPM (Longest Prefix Match) library
+ with better control plane (RIB) performance.
+ The data plane (FIB) can be extended with new algorithms.
+
* **Updated testpmd.**
* Added a console command to testpmd app, ``show port (port_id) ptypes`` which
gives ability to print port supported ptypes in different protocol layers.
+* **Added new example l2fwd-event application.**
+
+ Added an example application `l2fwd-event` that adds event device support to
+ traditional l2fwd example. It demonstrates usage of poll and event mode IO
+ mechanism under a single application.
+
+* **Added build support for Link Time Optimization.**
+
+ LTO is an optimization technique used by the compiler to perform whole
+ program analysis and optimization at link time. In order to do that
+ compilers store their internal representation of the source code that
+ the linker uses at the final stage of compilation process.
+
+ See :doc:`../prog_guide/lto` for more information:
+
Removed Items
-------------
* Quota and Watermark
* vhost-scsi
+* Removed arm64-dpaa2-* build config. arm64-dpaa-* can now build for both
+ dpaa and dpaa2 platforms.
+
API Changes
-----------
* mem: hid the internal ``malloc_heap`` structure and the
``rte_malloc_heap.h`` header.
+* vfio: removed ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` that have
+ been marked as deprecated in release 19.05.
+ ``rte_vfio_container_dma_map`` and ``rte_vfio_container_dma_unmap`` can
+ be used as substitutes.
+
* pci: removed the following functions deprecated since dpdk v17.11:
- ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
* ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to
``int`` to provide a way to report various error conditions.
+* ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
+ The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
+ If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
+ are better port iterators.
+
+* ethdev: RTE_FLOW_ITEM_TYPE_META data endianness altered to host one.
+ Due to the new dynamic metadata field in mbuf is host-endian either, there
+ is the minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dymanic one.
+ PKT_TX_METADATA flag is replaced with PKT_TX_DYNF_METADATA.
+ DEV_TX_OFFLOAD_MATCH_METADATA offload flag is removed, now metadata
+ support in PMD is engaged on dynamic field registration.
+
* event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
has been introduced in this release is used when used when all the packets
align the Ethernet header on receive and all known encapsulations
preserve the alignment of the header.
+* security: The field ``replay_win_sz`` has been moved from ipsec library
+ based ``rte_ipsec_sa_prm`` structure to security library based structure
+ ``rte_security_ipsec_xform``, which specify the Anti replay window size
+ to enable sequence replay attack handling.
+
+* ipsec: The field ``replay_win_sz`` has been removed from the structure
+ ``rte_ipsec_sa_prm`` as it has been added to the security library.
