* 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``.
-* eal: the ``rte_mem_config`` struct will be made private to remove it from the
- externally visible ABI and allow it to be updated in the future.
-
* eal: both declaring and identifying devices will be streamlined in v18.11.
New functions will appear to query a specific port from buses, classes of
device and device drivers. Device declaration will be made coherent with the
+ ``rte_eal_devargs_type_count``
+* eal: The ``rte_cpu_check_supported`` function has been deprecated since
+ v17.08 and will be removed.
+
+* eal: The ``rte_malloc_virt2phy`` function has been deprecated and replaced
+ by ``rte_malloc_virt2iova`` since v17.11 and will be removed.
+
* vfio: removal of ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` APIs which
have been replaced with ``rte_dev_dma_map`` and ``rte_dev_dma_unmap``
functions. The due date for the removal targets DPDK 20.02.
structure would be made internal (or removed if all dependencies are cleared)
in future releases.
+* net: The Ethernet address and header definitions will change
+ attributes. The Ethernet address struct will no longer be marked as
+ packed since the packed attribute is meaningless on a byte
+ array. The Ethernet header will be marked as aligned on a 2-byte
+ boundary and will no longer have the packed attribute. This allows
+ for efficient access on CPU architectures where unaligned access is
+ expensive. 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.
+
+* ethdev: The function ``rte_eth_dev_count`` will be removed in DPDK 20.02.
+ It is replaced by the function ``rte_eth_dev_count_avail``.
+ If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
+ are better port iterators.
+
* ethdev: the legacy filter API, including
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
-* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
- disable features supported by the crypto device. Only the following features
- would be allowed to be disabled this way,
-
- - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``
- - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``
- - ``RTE_CRYPTODEV_FF_SECURITY``
-
- Disabling unused features would facilitate efficient usage of HW/SW offload.
-
- - Member ``uint64_t ff_disable`` in ``rte_cryptodev_config``
-
- The field would be added in v19.08.
-
-* cryptodev: the ``uint8_t *data`` member of ``key`` structure in the xforms
- structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and
- ``rte_crypto_aead_xform``) will be changed to ``const uint8_t *data``.
+* ethdev: Update API functions returning ``void`` to return ``int`` with
+ negative errno values to indicate various error conditions (e.g.
+ invalid port ID, unsupported operation, failed operation):
+
+ - ``rte_eth_dev_stop``
+ - ``rte_eth_dev_close``
+
+* ethdev: New offload flags ``DEV_RX_OFFLOAD_RSS_HASH`` and
+ ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
+ This will allow application to enable or disable PMDs from updating
+ ``rte_mbuf::hash::rss`` and ``rte_mbuf::hash::fdir`` respectively.
+ This scheme will allow PMDs to avoid writes to ``rte_mbuf`` fields on Rx and
+ thereby improve Rx performance if application wishes do so.
+ In 19.11 PMDs will still update the fields even when the offloads are not
+ enabled.
+
+* ethdev: New function ``rte_eth_dev_set_supported_ptypes`` will be added in
+ 19.11.
+ This will allow application to request PMD to set specific ptypes defined
+ through ``rte_eth_dev_set_supported_ptypes`` in ``rte_mbuf::packet_type``.
+ If application doesn't want any ptype information it can call
+ ``rte_eth_dev_set_supported_ptypes(ethdev_id, RTE_PTYPE_UNKNOWN)`` and PMD
+ will set ``rte_mbuf::packet_type`` to ``0``.
+ If application doesn't call ``rte_eth_dev_set_supported_ptypes`` PMD can
+ return ``rte_mbuf::packet_type`` with ``rte_eth_dev_get_supported_ptypes``.
+ If application is interested only in L2/L3 layer, it can inform the PMD
+ to update ``rte_mbuf::packet_type`` with L2/L3 ptype by calling
+ ``rte_eth_dev_set_supported_ptypes(ethdev_id, RTE_PTYPE_L2_MASK | RTE_PTYPE_L3_MASK)``.
+ This scheme will allow PMDs to avoid lookup to internal ptype table on Rx and
+ thereby improve Rx performance if application wishes do so.
+
+* ethdev: New 32-bit fields may be added for maximum LRO session size, in
+ struct ``rte_eth_dev_info`` for the port capability and in struct
+ ``rte_eth_rxmode`` for the port configuration.
* cryptodev: support for using IV with all sizes is added, J0 still can
be used but only when IV length in following structs ``rte_crypto_auth_xform``,
