Deprecation Notices
-------------------
-* The following fields have been deprecated in rte_eth_stats:
- ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
- tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
-
-* ABI changes are planned for struct rte_eth_fdir_flow_ext in order to support
- flow director filtering in VF. The release 2.1 does not contain these ABI
- changes, but release 2.2 will, and no backwards compatibility is planned.
-
-* ABI changes are planned for struct rte_eth_fdir_filter and
- rte_eth_fdir_masks in order to support new flow director modes,
- MAC VLAN and Cloud, on x550. The MAC VLAN mode means the MAC and
- VLAN are monitored. The Cloud mode is for VxLAN and NVGRE, and
- the tunnel type, TNI/VNI, inner MAC and inner VLAN are monitored.
- The release 2.2 will contain these changes without backwards compatibility.
-
-* ABI changes are planned for struct virtio_net in order to support vhost-user
- multiple queues feature.
- It should be integrated in release 2.2 without backward compatibility.
-
-* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
- allow for a larger number of subport entries.
- The number of available traffic_classes and queues may also change.
- The mbuf structure element for sched hierarchy will also change from a single
- 32 bit to a 64 bit structure.
-
-* The scheduler statistics structure will change to allow keeping track of
- RED actions.
-
-* librte_table: New functions for table entry bulk add/delete will be added
- to the table operations structure.
-
-* librte_table hash: Key mask parameter will be added to the hash table
- parameter structure for 8-byte key and 16-byte key extendible bucket and
- LRU tables.
-
-* librte_pipeline: The prototype for the pipeline input port, output port
- and table action handlers will be updated:
- the pipeline parameter will be added, the packets mask parameter will be
- either removed (for input port action handler) or made input-only.
+* igb_uio: iomem mapping and sysfs files created for iomem and ioport in
+ igb_uio will be removed, because we are able to detect these from what Linux
+ has exposed, like the way we have done with uio-pci-generic. This change
+ targets release 17.05.
+
+* ABI/API changes are planned for 17.02: ``rte_device``, ``rte_driver`` will be
+ impacted because of introduction of a new ``rte_bus`` hierarchy. This would
+ also impact the way devices are identified by EAL. A bus-device-driver model
+ will be introduced providing a hierarchical view of devices.
+
+* ``eth_driver`` is planned to be removed in 17.02. This currently serves as
+ a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will
+ provide a way to handle device initialization currently being done in
+ ``eth_driver``.
+
+* In 17.02 ABI changes are planned: the ``rte_eth_dev`` structure will be
+ extended with new function pointer ``tx_pkt_prepare`` 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.
+
+* ethdev: an API change is planned for 17.02 for the function
+ ``_rte_eth_dev_callback_process``. In 17.02 the function will return an ``int``
+ instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
+
+* ABI changes are planned for 17.02 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. A
+ ``timestamp`` will also be added.
+
+* 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 until 16.11 and will be removed in 17.02.
+
+* 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.
+
+* 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.
