1 ABI and API Deprecation
2 =======================
4 See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
5 API and ABI deprecation notices are to be posted here.
11 * In 16.11 ABI changes are planned: the ``rte_eth_dev`` structure will be
12 extended with new function pointer ``tx_pkt_prep`` allowing verification
13 and processing of packet burst to meet HW specific requirements before
14 transmit. Also new fields will be added to the ``rte_eth_desc_lim`` structure:
15 ``nb_seg_max`` and ``nb_mtu_seg_max`` providing information about number of
16 segments limit to be transmitted by device for TSO/non-TSO packets.
18 * ABI changes are planned for 17.02 in the ``rte_mbuf`` structure: some fields
19 may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
20 ``nb_segs`` in one operation, because some platforms have an overhead if the
21 store address is not naturally aligned. Other mbuf fields, such as the
22 ``port`` field, may be moved or removed as part of this mbuf work. A
23 ``timestamp`` will also be added.
25 * The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
26 are respectively replaced by PKT_RX_VLAN_STRIPPED and
27 PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
28 their behavior will be kept until 16.11 and will be removed in 17.02.
30 * mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count``
31 will be removed in 17.02.
32 They are replaced by ``rte_mempool_avail_count`` and
33 ``rte_mempool_in_use_count`` respectively.
35 * mempool: The functions for single/multi producer/consumer are deprecated
36 and will be removed in 17.02.
37 It is replaced by ``rte_mempool_generic_get/put`` functions.
