-* The ethdev library file will be renamed from libethdev.* to librte_ethdev.*
- in release 16.11 in order to have a more consistent namespace.
-
-* In 16.11 ABI changes are planned: the ``rte_eth_dev`` structure will be
- extended with new function pointer ``tx_pkt_prep`` allowing verification
- and processing of packet burst to meet HW specific requirements before
- transmit. Also new fields will be added to the ``rte_eth_desc_lim`` structure:
- ``nb_seg_max`` and ``nb_mtu_seg_max`` providing information about number of
- segments limit to be transmitted by device for TSO/non-TSO packets.
-
-* The ethdev hotplug API is going to be moved to EAL with a notification
- mechanism added to crypto and ethdev libraries so that hotplug is now
- available to both of them. This API will be stripped of the device arguments
- so that it only cares about hotplugging.
-
-* Structures embodying pci and vdev devices are going to be reworked to
- integrate new common rte_device / rte_driver objects (see
- http://dpdk.org/ml/archives/dev/2016-January/031390.html).
- ethdev and crypto libraries will then only handle those objects so that they
- do not need to care about the kind of devices that are being used, making it
- easier to add new buses later.
-
-* ABI changes are planned for 16.11 in the ``rte_mbuf`` structure: some fields
- may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
- ``nb_segs`` in one operation, because some platforms have an overhead if the
- store address is not naturally aligned. Other mbuf fields, such as the
- ``port`` field, may be moved or removed as part of this mbuf work.
-
-* The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
- are respectively replaced by PKT_RX_VLAN_STRIPPED and
- PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
- their behavior will be kept in 16.07 and will be removed in 16.11.
-
-* mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count``
- will be removed in 17.02.
- They are replaced by ``rte_mempool_avail_count`` and
- ``rte_mempool_in_use_count`` respectively.
-
-* mempool: The functions for single/multi producer/consumer are deprecated
- and will be removed in 17.02.
- It is replaced by ``rte_mempool_generic_get/put`` functions.
-
-* API will change for ``rte_port_source_params`` and ``rte_port_sink_params``
- structures. The member ``file_name`` data type will be changed from
- ``char *`` to ``const char *``. This change targets release 16.11.
+* eal: both declaring and identifying devices will be streamlined in v18.05.
+ 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
+ new scheme of device identification.
+ As such, ``rte_devargs`` device representation will change.
+
+ - removal of ``name`` and ``args`` fields.
+ - The enum ``rte_devtype`` was used to identify a bus and will disappear.
+ - The ``rte_devargs_list`` will be made private.
+ - Functions previously deprecated will change or disappear:
+
+ + ``rte_eal_devargs_add``
+ + ``rte_eal_devargs_type_count``
+ + ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
+ + ``rte_eal_devargs_parse`` will change its format and use.
+ + all ``rte_devargs`` related functions will be renamed, changing the
+ ``rte_eal_devargs_`` prefix to ``rte_devargs_``.
+
+* pci: Several exposed functions are misnamed.
+ The following functions are deprecated starting from v17.11 and are replaced:
+
+ - ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
+ - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
+ - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
+
+* eal: The semantics of the return value for the ``rte_lcore_has_role`` function
+ are planned to change in v18.05. The function currently returns 0 and <0 for
+ success and failure, respectively. This will change to 1 and 0 for true and
+ false, respectively, to make use of the function more intuitive.
+
+* eal: a new set of mbuf mempool ops name APIs for user, platform and best
+ mempool names have been defined in ``rte_mbuf`` in v18.02. The uses of
+ ``rte_eal_mbuf_default_mempool_ops`` shall be replaced by
+ ``rte_mbuf_best_mempool_ops``.
+ The following function is now redundant and it is target to be deprecated
+ in 18.05:
+
+ - ``rte_eal_mbuf_default_mempool_ops``
+
+* mempool: several API and ABI changes are planned in v18.05.
+ The following functions, introduced for Xen, which is not supported
+ anymore since v17.11, are hard to use, not used anywhere else in DPDK.
+ Therefore they will be deprecated in v18.05 and removed in v18.08:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+
+ The following changes are planned:
+
+ - removal of ``get_capabilities`` mempool ops and related flags.
+ - substitute ``register_memory_area`` with ``populate`` ops.
+ - addition of new ops to customize required memory chunk calculation,
+ customize objects population and allocate contiguous
+ block of objects if underlying driver supports it.
+
+* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
+ definition in line with the ethdev TM and MTR APIs. Currently, this field
+ is defined in librte_sched in a non-generic way. The new generic format
+ will contain: queue ID, traffic class, color. Field size will not change.
+
+* ethdev: a new Tx and Rx offload API was introduced on 17.11.
+ In the new API, offloads are divided into per-port and per-queue offloads.
+ Offloads are disabled by default and enabled per application request.
+
+ The old ethdev - drivers offload interface will be deprecated on 18.05.
+ This includes:
+ - removal of the conversion in ethdev from new offloading API to old API for drivers.
+
+ In later releases the old offloading API will be deprecated, which will include:
+ - removal of ``ETH_TXQ_FLAGS_NO*`` flags.
+ - removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
+ - removal of the offloads bit-field from ``rte_eth_rxmode`` struct.
+
+* 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,
+ HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
+ PMDs that implement the latter.
+ Target release for removal of the legacy API will be defined once most
+ PMDs have switched to rte_flow.
+
+* ethdev: A new rss level field planned in 18.05.
+ The new API add rss_level field to ``rte_eth_rss_conf`` to enable a choice
+ of RSS hash calculation on outer or inner header of tunneled packet.
+
+* ethdev: A work is being planned for 18.05 to expose VF port representors
+ as a mean to perform control and data path operation on the different VFs.
+ As VF representor is an ethdev port, new fields are needed in order to map
+ between the VF representor and the VF or the parent PF. Those new fields
+ are to be included in ``rte_eth_dev_info`` struct.
+
+* i40e: The default flexible payload configuration which extracts the first 16
+ bytes of the payload for RSS will be deprecated starting from 18.02. If
+ required the previous behavior can be configured using existing flow
+ director APIs. There is no ABI/API break. This change will just remove a
+ global configuration setting and require explicit configuration.
