DPDK Release 21.08
==================
.. **Read this first.**
The text in the sections below explains how to update the release notes.
Use proper spelling, capitalization and punctuation in all sections.
Variable and config names should be quoted as fixed width text:
``LIKE_THIS``.

New Features
------------
.. This section should contain new features added in this release.
Sample format:
* **Add a title in the past tense with a full stop.**
Add a short 1-2 sentence description in the past tense.
The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.
* Enhanced feature bar to do something else.
Refer to the previous release notes for examples.
Suggested order in release notes items:
* Core libs (EAL, mempool, ring, mbuf, buses)
* Device abstraction libs and PMDs (ordered alphabetically by vendor name)
- ethdev (lib, PMDs)
- cryptodev (lib, PMDs)
- eventdev (lib, PMDs)
- etc
* Other libs
* Apps, Examples, Tools (if significant)
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.

bus/auxiliary: introduce auxiliary bus Auxiliary bus [1] provides a way to split function into child-devices representing sub-domains of functionality. Each auxiliary device represents a part of its parent functionality. Auxiliary device is identified by unique device name, sysfs path: /sys/bus/auxiliary/devices/<name> Devargs legacy syntax of auxiliary device: -a auxiliary:<name>[,args...] Devargs generic syntax of auxiliary device: -a bus=auxiliary,name=<name>/class=<class>/driver=<driver>[,args...] [1] kernel auxiliary bus document: https://www.kernel.org/doc/html/latest/driver-api/auxiliary_bus.html Signed-off-by: Xueming Li <xuemingl@nvidia.com> Acked-by: Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru> Acked-by: Thomas Monjalon <thomas@monjalon.net>

Auxiliary bus provides a way to split function into child-devices
representing sub-domains of functionality. Each auxiliary device
represents a part of its parent functionality.
eal: handle compressed firmware Introduce an internal firmware loading helper to remove code duplication in our drivers and handle xz compressed firmware by calling libarchive. This helper tries to look for .xz suffixes so that drivers are not aware the firmware has been compressed. libarchive is set as an optional dependency: without libarchive, a runtime warning is emitted so that users know there is a compressed firmware. Windows implementation is left as an empty stub.

* **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.
net/iavf: query QoS capabilities and set queue TC mapping This patch added the support for VF to config the ETS-based Tx QoS, including querying current QoS configuration from PF and config queue TC mapping. PF QoS is configured in advance and the queried info is provided to the user for future usage. VF queues are mapped to different TCs in PF through virtchnl.

net/ice: add AVX2 offload Rx Add a specific path for RX AVX2. In this path, support the HW offload features, like, checksum, VLAN stripping, RSS hash. This path is chosen automatically according to the configuration. 'inline' is used, then the duplicate code is generated by the compiler.

* **Updated Intel ice driver.**
* In AVX2 code, added the new RX and TX paths to use the 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.
net/ice: support QoS config VF bandwidth in DCF This patch supports the ETS-based QoS configuration. It enables the DCF to configure bandwidth limits for each VF VSI of different TCs. A hierarchy scheduler tree is built with port, TC and VSI nodes.

truncation.
eal: use callbacks for power monitoring comparison Previously, the semantics of power monitor were such that we were checking current value against the expected value, and if they matched, then the sleep was aborted. This is somewhat inflexible, because it only allowed us to check for a specific value in a specific way. This commit replaces the comparison with a user callback mechanism, so that any PMD (or other code) using `rte_power_monitor()` can define their own comparison semantics and decision making on how to detect the need to abort the entering of power optimized state. Existing implementations are adjusted to follow the new semantics.
