Deprecation Notices
-------------------
-* eal: certain structures will change in EAL on account of upcoming external
- memory support. Aside from internal changes leading to an ABI break, the
- following externally visible changes will also be implemented:
-
- - ``rte_memseg_list`` will change to include a boolean flag indicating
- whether a particular memseg list is externally allocated. This will have
- implications for any users of memseg-walk-related functions, as they will
- now have to skip externally allocated segments in most cases if the intent
- is to only iterate over internal DPDK memory.
- - ``socket_id`` parameter across the entire DPDK will gain additional meaning,
- as some socket ID's will now be representing externally allocated memory. No
- changes will be required for existing code as backwards compatibility will
- be kept, and those who do not use this feature will not see these extra
- socket ID's.
+* meson: The minimum supported version of meson for configuring and building
+ DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
+ those users with a version earlier than 0.47.1, an updated copy of meson
+ can be got using the ``pip``, or ``pip3``, tool for downloading python
+ packages.
+
+* kvargs: The function ``rte_kvargs_process`` will get a new parameter
+ for returning key match count. It will ease handling of no-match case.
* 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
+ ``rte_eal_devargs_type_count``
+* 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.
+
* pci: Several exposed functions are misnamed.
The following functions are deprecated starting from v17.11 and are replaced:
- ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
- ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
-* 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.
-
-* mbuf: the macro ``RTE_MBUF_INDIRECT()`` will be removed in v18.08 or later and
- replaced with ``RTE_MBUF_CLONED()`` which is already added in v18.05. As
- ``EXT_ATTACHED_MBUF`` is newly introduced in v18.05, ``RTE_MBUF_INDIRECT()``
- can no longer be mutually exclusive with ``RTE_MBUF_DIRECT()`` if the new
- experimental API ``rte_pktmbuf_attach_extbuf()`` is used. Removal of the macro
- is to fix this semantic inconsistency.
-
-* ethdev: In v18.11 ``DEV_RX_OFFLOAD_CRC_STRIP`` offload flag will be removed, default
- behavior without any flag will be changed to CRC strip.
- To keep CRC ``DEV_RX_OFFLOAD_KEEP_CRC`` flag is required.
- ``KEEP_CRC``: Keep CRC in packet
- No flag: Strip CRC from packet
+* dpaa2: removal of ``rte_dpaa2_memsegs`` structure which has been replaced
+ by a pa-va search library. This structure was earlier being used for holding
+ memory segments used by dpaa2 driver for faster pa->va translation. This
+ structure would be made internal (or removed if all dependencies are cleared)
+ in future releases.
* ethdev: the legacy filter API, including
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
-* ethdev: In v18.11 ``rte_eth_dev_attach()`` and ``rte_eth_dev_detach()``
- will be removed.
- Hotplug functions ``rte_eal_hotplug_add()`` and ``rte_eal_hotplug_remove()``
- should be used instread.
- Function ``rte_eth_dev_get_port_by_name()`` may be used to find
- identifier of the added port.
-
-* eal: In v18.11 ``rte_eal_dev_attach()`` and ``rte_eal_dev_detach()``
- will be removed.
- Hotplug functions ``rte_eal_hotplug_add()`` and ``rte_eal_hotplug_remove()``
- should be used directly.
-
-* pdump: As we changed to use generic IPC, some changes in APIs and structure
- are expected in subsequent release.
-
- - ``rte_pdump_set_socket_dir`` will be removed;
- - The parameter, ``path``, of ``rte_pdump_init`` will be removed;
- - The enum ``rte_pdump_socktype`` will be removed.
-
-* ethdev: flow API function ``rte_flow_copy()`` will be deprecated in v18.11
- in favor of ``rte_flow_conv()`` (which will appear in that version) and
- subsequently removed for v19.02.
-
- This is due to a lack of flexibility and reliance on a type unusable with
- C++ programs (struct rte_flow_desc).
+* ethdev: Maximum and minimum MTU values vary between hardware devices. In
+ hardware agnostic DPDK applications access to such information would allow
+ a more accurate way of validating and setting supported MTU values on a per
+ device basis rather than using a defined default for all devices. To
+ resolve this, the following members will be added to ``rte_eth_dev_info``.
+ Note: these can be added to fit a hole in the existing structure for amd64
+ but not for 32-bit, as such ABI change will occur as size of the structure
+ will increase.
+
+ - Member ``uint16_t min_mtu`` the minimum MTU allowed.
+ - Member ``uint16_t max_mtu`` the maximum MTU allowed.
+
+* kni: remove KNI ethtool support. To clarify, this is not to remove the KNI,
+ but only to remove ethtool support of it that is disabled by default and
+ can be enabled via ``CONFIG_RTE_KNI_KMOD_ETHTOOL`` config option.
+ Existing KNI ethtool implementation is only supported by ``igb`` & ``ixgbe``
+ drivers, by using a copy of kernel drivers in DPDK. This model cannot be
+ extended to all drivers in DPDK and it is too much effort to maintain
+ kernel modules in DPDK. As a result users won't be able to use ``ethtool``
+ via ``igb`` & ``ixgbe`` anymore.
+
+* meter: New ``rte_color`` definition will be added in 19.02 and that will
+ replace ``enum rte_meter_color`` in meter library in 19.05. This will help
+ to consolidate color definition, which is currently replicated in many places,
+ such as: rte_meter.h, rte_mtr.h, rte_tm.h.
+
+* crypto/aesni_mb: the minimum supported intel-ipsec-mb library version will be
+ changed from 0.49.0 to 0.52.0.
