* meson: The minimum supported version of meson for configuring and building
DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
those users with a version earlier than 0.47.1, an updated copy of meson
- can be got using the ``pip``, or ``pip3``, tool for downloading python
- packages.
+ can be got using the ``pip3`` tool (or ``python3 -m pip``) for downloading
+ python packages.
* kvargs: The function ``rte_kvargs_process`` will get a new parameter
for returning key match count. It will ease handling of no-match case.
These wrappers must be used for patches that need to be merged in 20.08
onwards. This change will not introduce any performance degradation.
-* igb_uio: In the view of reducing the kernel dependency from the main tree,
- as a first step, the Technical Board decided to move ``igb_uio``
- kernel module to the dpdk-kmods repository in the /linux/igb_uio/ directory
- in 20.11.

* lib: will fix extending some enum/define breaking the ABI. There are multiple
samples in DPDK that enum/define terminated with a ``.*MAX.*`` value which is
used by iterators, and arrays holding these values are sized with this
following the IPv6 header, as proposed in RFC
https://mails.dpdk.org/archives/dev/2020-August/177257.html.
-* vhost: Vhost-user dequeue zero-copy support will be removed in 20.11.
- The only known user is OVS where the feature is still experimental,
- and has not received any update for 2.5 years.
- This feature faces reliability issues and is often conflicting with
- new features being implemented.
-
* security: The API ``rte_security_session_create`` takes only single mempool
for session and session private data. So the application need to create
mempool for twice the number of sessions needed and will also lead to
- https://patches.dpdk.org/patch/71457/
- https://patches.dpdk.org/patch/71456/
-* acl: ``RTE_ACL_CLASSIFY_NUM`` enum value will be removed.
- This enum value is not used inside DPDK, while it prevents to add new
- classify algorithms without causing an ABI breakage.
-
* sched: To allow more traffic classes, flexible mapping of pipe queues to
traffic classes, and subport level configuration of pipes and queues
changes will be made to macros, data structures and API functions defined
in "rte_sched.h". These changes are aligned to improvements suggested in the
RFC https://mails.dpdk.org/archives/dev/2018-November/120035.html.
-* sched: To allow dynamic configuration of the subport bandwidth profile,
- changes will be made to data structures ``rte_sched_subport_params``,
- ``rte_sched_port_params`` and new data structure, API functions will be
- defined in ``rte_sched.h``. These changes are aligned as suggested in the
- RFC https://mails.dpdk.org/archives/dev/2020-July/175161.html
-
* metrics: The function ``rte_metrics_init`` will have a non-void return
in order to notify errors instead of calling ``rte_exit``.
In this case the function will return -1 unless the environment is unset first
(using ``rte_power_unset_env``). Other function usage scenarios will not change.
-* python: Since the beginning of 2020, Python 2 has officially reached
- end-of-support: https://www.python.org/doc/sunset-python-2/.
- Python 2 support will be completely removed in 20.11.
- In 20.08, explicit deprecation warnings will be displayed when running
- scripts with Python 2.
+* cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
+ content. On Linux and FreeBSD, supported prior to DPDK 20.11,
+ original structure will be kept until DPDK 21.11.
* dpdk-setup.sh: This old script relies on deprecated stuff, and especially
``make``. Given environments are too much variables for such a simple script,
