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
- - ethdev (lib, PMDs)
- - cryptodev (lib, PMDs)
- - eventdev (lib, PMDs)
- - etc
- * Other libs
- * Apps, Examples, Tools (if significant)

* **Added non-EAL threads registration API.**
Added a new API to register non-EAL threads as lcores. This can be used by
- applications to have its threads known of DPDK without suffering from the
+ applications to have its threads known to DPDK without suffering from the
non-EAL previous limitations in terms of performance.
-* **rte_*mb APIs are updated to use DMB instruction for ARMv8.**
+* **rte_*mb APIs are updated to use the DMB instruction for ARMv8.**
ARMv8 memory model has been strengthened to require other-multi-copy
- atomicity. This allows for using DMB instruction instead of DSB for IO
- barriers. rte_*mb APIs, for ARMv8 platforms, are changed to use DMB
+ atomicity. This allows for using the DMB instruction instead of DSB for IO
+ barriers. The rte_*mb APIs, for ARMv8 platforms, have changed to use the DMB
instruction to reflect this.
* **Added support for RTS and HTS modes into mempool ring driver.**
- Added ability to select new ring synchronisation modes:
+ Added the ability to select new ring synchronisation modes:
``relaxed tail sync (ring_mt_rts)`` and ``head/tail sync (ring_mt_hts)``
- via mempool ops API.
+ via the mempool ops API.
* **Added the support for vfio-pci new VF token interface.**
- From Linux 5.7, vfio-pci supports to bind both SR-IOV PF and the created VFs,
- it uses a shared VF token (UUID) to represent the collaboration between PF
- and VFs. Update DPDK PCI driver to gain the access to the PF and VFs devices
- by appending the VF token parameter.

+ * Async device channel register/unregister APIs.
+ * Async packets enqueue/completion APIs (only split ring was implemented).
* **Added vDPA device APIs to query virtio queue statistics.**
- A new 3 APIs has been added to query virtio queue statistics, to get their
- names and to reset them by a vDPA device.

The ``ECPRI`` item has been added to support eCPRI packet offloading for
5G network.
-* **Introduced send packet scheduling on the timestamps.**
+* **Introduced send packet scheduling based on timestamps.**
- Added the new mbuf dynamic field and flag to provide timestamp on what packet
- transmitting can be synchronized. The device Tx offload flag is added to
- indicate the PMD supports send scheduling.
