DPDK Release 22.03
==================
New Features
------------
* **Added ability to reuse hugepages in Linux.**
It is now possible to reuse files in hugetlbfs to speed up hugepage mapping,
which may be useful for fast restart and large allocations.
The new mode is activated with ``--huge-unlink=never``
and has security implications, refer to the user and programmer guides.
* **Added functions to calculate UDP/TCP checksum in mbuf.**
Added the following functions to calculate UDP/TCP checksum of packets
which can be over multi-segments:
- ``rte_ipv4_udptcp_cksum_mbuf()``
- ``rte_ipv4_udptcp_cksum_mbuf_verify()``
- ``rte_ipv6_udptcp_cksum_mbuf()``
- ``rte_ipv6_udptcp_cksum_mbuf_verify()``
* **Added functions to configure the flow engine.**
Added the ``rte_flow_configure`` API to configure the flow management
engine, allowing preallocation of some resources for better performance.
Added ``rte_flow_info_get`` API to retrieve available resources.
Added ``rte_flow_template_table_create`` API to group flow rules
with the same flow attributes and common matching patterns and actions
defined by ``rte_flow_pattern_template_create`` and
``rte_flow_actions_template_create`` respectively.
The corresponding functions to destroy these entities are:
``rte_flow_template_table_destroy``, ``rte_flow_pattern_template_destroy``
and ``rte_flow_actions_template_destroy``.
* **Added functions for asynchronous flow rules creation and destruction.**
Added the ``rte_flow_async_create`` and ``rte_flow_async_destroy`` APIs
to enqueue flow creation/destruction operations asynchronously as well as
``rte_flow_pull`` to poll and retrieve results of these operations and
``rte_flow_push`` to push all the in-flight operations to the NIC.
Added asynchronous APIs for indirect actions management:
- ``rte_flow_async_action_handle_create``
- ``rte_flow_async_action_handle_destroy``
- ``rte_flow_async_action_handle_update``
* **Added rte_flow support for matching GRE optional fields.**
Added ``gre_option`` item in rte_flow to support checksum/key/sequence
matching in GRE packets.
* **Added new RSS offload types for L2TPv2 in RSS flow.**
Added ``RTE_ETH_RSS_L2TPV2`` macro so that he L2TPv2 session ID field can be used as
input set for RSS.
* **Added IP reassembly Ethernet offload APIs to get and set config.**
Added IP reassembly offload APIs which provide functions to query IP
reassembly capabilities, to set configuration and to get currently set
reassembly configuration.
* **Added an API to enable queue based priority flow ctrl (PFC).**
Added new APIs, ``rte_eth_dev_priority_flow_ctrl_queue_info_get()`` and
``rte_eth_dev_priority_flow_ctrl_queue_configure()`` for queue based
priority flow ctrl (PFC).
* **Added a private dump API, to dump private info from device.**
Added the private dump API which provides a facility for querying private info from a device.
There exists many private properties in different PMD drivers and
the information in these properties is useful for debugging.
* **Updated AF_XDP PMD.**
* Added support for libxdp >= v1.2.2.
* Re-enabled secondary process support. RX/TX is not supported.
* **Updated Amazon ENA PMD.**
The new driver version (v2.6.0) introduces bug fixes and improvements, including:
* Added new checksum related xstats: ``l3_csum_bad``, ``l4_csum_bad`` and
``l4_csum_good``.
* Added support for the link status configuration.
* Added optimized memcpy support for the ARM platforms.
* Added ENA admin queue support for the MP applications.
* Added free Tx mbuf on demand feature support.
* Added ``rte_eth_xstats_get_names_by_id`` API support.
* Added ``miss_txc_to`` device argument for setting the Tx completion timeout.
* **Updated Cisco enic driver.**
* Added rte_flow support for matching GENEVE packets.
* Added rte_flow support for matching eCPRI packets.
* **Updated Intel iavf driver.**
* Added L2TPv2 (include PPP over L2TPv2) RSS support based on outer
MAC src/dst address and L2TPv2 session ID.
* Added L2TPv2 (include PPP over L2TPv2) FDIR support based on outer
MAC src/dst address and L2TPv2 session ID.
* Added PPPoL2TPv2oUDP FDIR distribute packets based on inner IP
src/dst address and UDP/TCP src/dst port.
* **Updated Marvell cnxk ethdev PMD.**
* Added queue based priority flow control support for CN9K and CN10K.
* Added support for IP reassembly for inline inbound IPsec packets.
* Added support for packet marking in traffic manager.
* Added support for CNF95xx B0 variant SoC.
* **Updated Mellanox mlx5 driver.**
* Added support for ConnectX-7 capability to schedule traffic sending on timestamp.
* Added WQE based hardware steering support with ``rte_flow_async`` API.
* Added steering for external Rx queue created outside the PMD.
* Added GRE optional fields matching.
* **Updated Wangxun ngbe driver.**
* Added support for devices of custom PHY interfaces.
- M88E1512 PHY connects to RJ45
- M88E1512 PHY connects to RGMII combo
- YT8521S PHY connects to SFP
* Added LED OEM support.
* **Updated Wangxun txgbe driver.**
Added LED OEM support.
* **Added an API for private user data in asymmetric crypto session.**
An API was added to get/set an asymmetric crypto session's user data.
* **Updated Marvell cnxk crypto PMD.**
* Added SHA256-HMAC support in lookaside protocol (IPsec) for CN10K.
* Added SHA384-HMAC support in lookaside protocol (IPsec) for CN9K & CN10K.
* Added SHA512-HMAC support in lookaside protocol (IPsec) for CN9K & CN10K.

* **Added an API to retrieve event port id of ethdev Rx adapter.**
The new API ``rte_event_eth_rx_adapter_event_port_get()`` was added.
* **Added support for Kunpeng930 DMA devices to HiSilicon DMA PMD.**
Kunpeng930 DMA devices are now enabled for HiSilicon DMA PMD.
* **Added CNXK GPIO PMD.**
Added a new rawdevice PMD which allows managing userspace GPIOs and installing
custom GPIO interrupt handlers which bypass the kernel. This is especially useful
for applications that as well as providing standard dataplane functionality
also want to have fast and low latency access to GPIO pin state.
See the :doc:`../rawdevs/cnxk_gpio` rawdev guide for more details on this
driver.
* **Updated testpmd to support software UDP/TCP checksum over multiple segments.**
Updated ``rte_ipv4/6_udptcp_cksum_mbuf()`` functions in testpmd csum mode
to support software UDP/TCP checksum over multiple segments.
* **Added crypto producer mode in test-eventdev.**
Crypto producer mode helps to measure performance of OP_NEW and OP_FORWARD
modes of event crypto adapter.
Removed Items
-------------
* **Removed experimental performance thread example application.**
API Changes
-----------
* net: added experimental functions ``rte_ipv4_udptcp_cksum_mbuf()``,
``rte_ipv4_udptcp_cksum_mbuf_verify()``, ``rte_ipv6_udptcp_cksum_mbuf()``,
``rte_ipv6_udptcp_cksum_mbuf_verify()``
* ethdev: Old public macros and enumeration constants without ``RTE_ETH_`` prefix,
which are kept for backward compatibility, are marked as deprecated.
* cryptodev: The asymmetric session handling was modified to use a single
mempool object. An API ``rte_cryptodev_asym_session_pool_create`` was added
to create a mempool with element size big enough to hold the generic asymmetric
session header, max size for a device private session data, and user data size.
The session structure was moved to ``cryptodev_pmd.h``,
hiding it from applications.
The API ``rte_cryptodev_asym_session_init`` was removed as the initialization
is now moved to ``rte_cryptodev_asym_session_create``, which was updated to
return an integer value to indicate initialisation errors.
ABI Changes
-----------
* No ABI change that would break compatibility with 21.11.
Known Issues
------------
* **Possible reduced power saving with PMD Power Management.**
Users may see reduced power savings when using PMD Power Management.
This issue occurs when compiling DPDK applications with GCC-9
on platforms with TSX enabled.
The function ``rte_power_monitor_multi()`` may return
without successfully starting the RTM transaction (``_xbegin()`` fails).
There are three workarounds for this issue.
Either build DPDK with GCC-11 or newer, build with shared libraries,
or build DPDK with fewer drivers.
