Deprecation Notices
|
|
-------------------
|
|
|
|
* 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 17.02.
|
|
|
|
* 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.
