DPDK Release 21.08
==================
New Features
------------
* **Added auxiliary bus support.**
An auxiliary bus provides a way to split a function into child-devices
representing sub-domains of functionality. Each auxiliary device
represents a part of its parent functionality.
* **Added XZ compressed firmware support.**
Using ``rte_firmware_read`` a driver can now handle XZ compressed firmware
in a transparent way, with EAL uncompressing using libarchive, if this library
is available when building DPDK.
* **Updated Amazon ENA PMD.**
Updated the Amazon ENA PMD. The new driver version (v2.4.0) introduced
bug fixes and improvements, including:
* Added Rx interrupt support.
* RSS hash function key reconfiguration support.
* **Updated Intel iavf driver.**
* Added Tx QoS VF queue TC mapping.
* Added FDIR and RSS for GTPoGRE, and support for filters based on GTPU TEID/QFI,
outermost L3 or innermost L3/L4.
* **Updated Intel ice driver.**
* Added new RX and TX paths in the AVX2 code to use HW offload
features. When the HW offload features are configured to be used, the
offload paths are chosen automatically. In parallel the support for HW
offload features was removed from the legacy AVX2 paths.
* Added Tx QoS TC bandwidth configuration in DCF.
* **Added support for Marvell CN10K SoC Ethernet device.**
* Added net/cnxk driver which provides the support for the integrated Ethernet
device.
* **Updated Mellanox mlx5 driver.**
* Added Sub-Function support based on auxiliary bus.
* Added support for meter hierarchy.
* Added support for metering policy actions of yellow color.
* Added support for metering trTCM RFC2698 and RFC4115.
* Added devargs option ``allow_duplicate_pattern``.
* Added matching on IPv4 Internet Header Length (IHL).
* Added support for matching on VXLAN header last 8-bits reserved field.
* Optimized multi-thread flow rule insertion rate.
* **Updated Solarflare network PMD.**
Updated the Solarflare ``sfc_efx`` driver with changes including:
* Added COUNT action support for SN1000 NICs.
* **Added Wangxun ngbe PMD.**
Added a new PMD for Wangxun 1Gb Ethernet NICs.
See the :doc:`../nics/ngbe` for more details.
* **Added inflight packets clear API in vhost library.**
Added an API which can clear the inflight packets submitted to
the DMA engine in the vhost async data path.
* **Updated Intel QuickAssist crypto PMD.**
Added fourth generation of QuickAssist Technology(QAT) devices support.
Only symmetric crypto has been currently enabled. Compression and asymmetric
crypto PMD will fail to create.
* **Added support for Marvell CNXK crypto driver.**
* Added cnxk crypto PMD which provides support for an integrated
crypto driver for CN9K and CN10K series of SOCs. Support for
symmetric crypto algorithms was added to both the PMDs.
* Added support for lookaside protocol (IPsec) offload in cn10k PMD.
* Added support for asymmetric crypto operations in cn9k and cn10k PMD.
* **Updated Marvell OCTEON TX crypto PMD.**
Added support for crypto adapter ``OP_FORWARD`` mode.
* **Added support for Nvidia crypto device driver.**
Added mlx5 crypto driver to support AES-XTS cipher operations.
The first device to support it is ConnectX-6.
* **Updated ISAL compress device PMD.**
The ISAL compress device PMD now supports Arm platforms.
* **Added Baseband PHY CNXK PMD.**
Added Baseband PHY PMD which allows configuration of the BPHY hardware block
comprising accelerators and DSPs specifically tailored for 5G/LTE inline
use cases. Configuration happens via standard rawdev enq/deq operations. See
the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.
* **Added support for Marvell CN10K, CN9K, event Rx/Tx adapter.**
* Added Rx/Tx adapter support for event/cnxk when the Ethernet device requested
is net/cnxk.
* Added support for event vectorization for Rx/Tx adapter.
* **Added cppc_cpufreq support to Power Management library.**
Added support for cppc_cpufreq driver which works on most arm64 platforms.
* **Added multi-queue support to Ethernet PMD Power Management.**
The experimental PMD power management API now supports managing
multiple Ethernet Rx queues per lcore.
* **Updated testpmd to output log errors to stderr.**
Updated testpmd application to output log errors and warnings to stderr
instead of stdout.
API Changes
-----------
* eal: ``rte_strscpy`` sets ``rte_errno`` to ``E2BIG`` in case of string
truncation.
* eal: ``rte_bsf32_safe`` now takes a 32-bit value for its first argument.
This fixes warnings about loss of precision
when used with some compilers settings.
* eal: ``rte_power_monitor`` and the ``rte_power_monitor_cond`` struct changed
to use a callback mechanism.
* rte_power: The experimental PMD power management API is no longer considered
to be thread safe; all Rx queues affected by the API will now need to be
stopped before making any changes to the power management scheme.
ABI Changes
-----------
* No ABI change that would break compatibility with 20.11.
Known Issues
------------
* **Last mbuf segment not implicitly reset.**
It is expected that free mbufs have their field ``nb_seg`` set to 1,
so that when it is allocated, the user does not need to set its value.
The mbuf free functions are responsible of resetting this field to 1
before returning the mbuf to the pool.
When a multi-segment mbuf is freed, the field ``nb_seg`` is not reset
to 1 for the last segment of the chain. On next allocation of this segment,
if the field is not explicitly reset by the user,
an invalid mbuf can be created, and can cause an undefined behavior.
This issue has a root cause in DPDK 17.05, meaning it is 4 years old.
A fix is available and discussed but not merged in DPDK 21.08:
