can be got using the ``pip``, or ``pip3``, tool for downloading python
packages.
+* build macros: The macros defining RTE_MACHINE_CPUFLAG_* will be removed
+ from the build. The information provided by these macros is available
+ through standard compiler macros. For example, RTE_MACHINE_CPUFLAG_SSE3
+ duplicates the compiler-provided macro __SSE3__.
+
* kvargs: The function ``rte_kvargs_process`` will get a new parameter
for returning key match count. It will ease handling of no-match case.
+* eal: To be more inclusive in choice of naming, the DPDK project
+ will replace uses of master/slave in the API's and command line arguments.
+
+ References to master/slave in relation to lcore will be renamed
+ to initial/worker. The function ``rte_get_master_lcore()``
+ will be renamed to ``rte_get_initial_lcore()``.
+ For the 20.11 release, both names will be present and the
+ old function will be marked with the deprecated tag.
+ The old function will be removed in a future version.
+
+ The iterator for worker lcores will also change:
+ ``RTE_LCORE_FOREACH_SLAVE`` will be replaced with
+ ``RTE_LCORE_FOREACH_WORKER``.
+
+ The ``master-lcore`` argument to testpmd will be replaced
+ with ``initial-lcore``. The old ``master-lcore`` argument
+ will produce a runtime notification in 20.11 release, and
+ be removed completely in a future release.
+
+* eal: The terms blacklist and whitelist to describe devices used
+ by DPDK will be replaced in the 20.11 relase.
+ This will apply to command line arguments as well as macros.
+
+ The macro ``RTE_DEV_BLACKLISTED`` will be replaced with ``RTE_DEV_EXCLUDED``
+ and ``RTE_DEV_WHITELISTED`` will be replaced with ``RTE_DEV_INCLUDED``
+ ``RTE_BUS_SCAN_BLACKLIST`` and ``RTE_BUS_SCAN_WHITELIST`` will be
+ replaced with ``RTE_BUS_SCAN_EXCLUDED`` and ``RTE_BUS_SCAN_INCLUDED``
+ respectively. Likewise ``RTE_DEVTYPE_BLACKLISTED_PCI`` and
+ ``RTE_DEVTYPE_WHITELISTED_PCI`` will be replaced with
+ ``RTE_DEVTYPE_EXCLUDED`` and ``RTE_DEVTYPE_INCLUDED``.
+
+ The old macros will be marked as deprecated in 20.11 and any
+ usage will cause a compile warning. They will be removed in
+ a future release.
+
+ The command line arguments to ``rte_eal_init`` will change from
+ ``-b, --pci-blacklist`` to ``-x, --exclude`` and
+ ``-w, --pci-whitelist`` to ``-i, --include``.
+ The old command line arguments will continue to be accepted in 20.11
+ but will cause a runtime warning message. The old arguments will
+ be removed in a future release.
+
* eal: The function ``rte_eal_remote_launch`` will return new error codes
after read or write error on the pipe, instead of calling ``rte_panic``.
In 19.11 PMDs will still update the field even when the offload is not
enabled.
+* ethdev: Add new fields to ``rte_eth_rxconf`` to configure the receiving
+ queues to split ingress packets into multiple segments according to the
+ specified lengths into the buffers allocated from the specified
+ memory pools. The backward compatibility to existing API is preserved.
+
* ethdev: ``rx_descriptor_done`` dev_ops and ``rte_eth_rx_descriptor_done``
will be deprecated in 20.11 and will be removed in 21.11.
Existing ``rte_eth_rx_descriptor_status`` and ``rte_eth_tx_descriptor_status``
as deprecated in DPDK 20.11, along with the associated macros ``ETH_MIRROR_*``.
This API will be fully removed in DPDK 21.11.
+* ethdev: The ``struct rte_flow_item_eth`` and ``struct rte_flow_item_vlan``
+ structs will be modified, to include an additional value, indicating existence
+ or absence of a VLAN header following the current header, as proposed in RFC
+ https://mails.dpdk.org/archives/dev/2020-August/177536.html.
+
+* ethdev: The ``struct rte_flow_item_ipv6`` struct will be modified to include
+ additional values, indicating existence or absence of IPv6 extension headers
+ following the IPv6 header, as proposed in RFC
+ https://mails.dpdk.org/archives/dev/2020-August/177257.html.
+
* ethdev: Some internal APIs for driver usage are exported in the .map file.
Now DPDK has ``__rte_internal`` marker so we can mark internal APIs and move
them to the INTERNAL block in .map. Although these APIs are internal it will
* pmd_dpaa: The API ``rte_pmd_dpaa_set_tx_loopback`` will have extended
``port_id`` definition from ``uint8_t`` to ``uint16_t``.
+* 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
``rte_rawdev_configure``, ``rte_rawdev_queue_conf_get`` and
``rte_rawdev_queue_setup``.
+* 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
