Removed Items
-------------
Also, make sure to start the actual text at the margin.
=========================================================
+* Removed library-level ABI versions. These have been replaced with a single
+ project-level ABI version for non-experimental libraries and an ABI version of
+ ``0`` for experimental libraries. Review the :doc:`../contributing/abi_policy`
+ and :doc:`../contributing/abi_versioning` guides for more information.
+
* Removed duplicated set of commands for Rx offload configuration from testpmd::
port config all crc-strip|scatter|rx-cksum|rx-timestamp|
hw-vlan|hw-vlan-filter|hw-vlan-strip|hw-vlan-extend on|off
- The testpmd commands set that can be used instead
- in order to enable or disable Rx offloading on all Rx queues of a port is::
+ The testpmd command set that can be used instead in order to enable or
+ disable Rx offloading on all Rx queues of a port is::
port config <port_id> rx_offload crc_strip|scatter|
ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
are better port iterators.
+* ethdev: ``RTE_FLOW_ITEM_TYPE_META`` data endianness altered to host one.
+ Due to the new dynamic metadata field in mbuf is host-endian either, there
+ is a minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dynamic one.
+ ``PKT_TX_METADATA`` flag is replaced with ``PKT_TX_DYNF_METADATA``.
+ ``DEV_TX_OFFLOAD_MATCH_METADATA`` offload flag is removed, now metadata
+ support in PMD is engaged on dynamic field registration.
+
* event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
has been introduced in this release is used when used when all the packets
- enqueued in the tx adapter are destined for the same Ethernet port & Tx queue.
+ enqueued in the Tx adapter are destined for the same Ethernet port ans Tx
+ queue.
* sched: The pipe nodes configuration parameters such as number of pipes,
pipe queue sizes, pipe profiles, etc., are moved from port level structure
Also, make sure to start the actual text at the margin.
=========================================================
+* policy: Please note the revisions to the :doc:`../contributing/abi_policy`
+ introducing major ABI versions, with DPDK 19.11 becoming the first major
+ version ``v20``. ABI changes to add new features continue to be permitted in
+ subsequent releases, with the condition that ABI compatibility with the major
+ ABI version is maintained.
+
* net: The Ethernet address and other header definitions have changed
attributes. They have been modified to be aligned on 2-byte boundaries.
These changes should not impact normal usage because drivers naturally
align the Ethernet header on receive and all known encapsulations
preserve the alignment of the header.
-* security: The field ``replay_win_sz`` has been moved from ipsec library
+* security: The field ``replay_win_sz`` has been moved from the ipsec library
based ``rte_ipsec_sa_prm`` structure to security library based structure
- ``rte_security_ipsec_xform``, which specify the Anti replay window size
+ ``rte_security_ipsec_xform``, which specify the anti-replay window size
to enable sequence replay attack handling.
* ipsec: The field ``replay_win_sz`` has been removed from the structure
``rte_ipsec_sa_prm`` as it has been added to the security library.
+* ethdev: Added 32-bit fields for maximum LRO aggregated packet size, in
+ struct ``rte_eth_dev_info`` for the port capability and in struct
+ ``rte_eth_rxmode`` for the port configuration.
+ Application should use the new field in struct ``rte_eth_rxmode`` to configure
+ the requested size.
+ PMD should use the new field in struct ``rte_eth_dev_info`` to report the
+ supported port capability.
