Deprecation Notices
-------------------
-* eal: both declaring and identifying devices will be streamlined in v18.05.
+* eal: DPDK runtime configuration file (located at
+ ``/var/run/.<prefix>_config``) will be moved. The new path will be as follows:
+
+ - if DPDK is running as root, path will be set to
+ ``/var/run/dpdk/<prefix>/config``
+ - if DPDK is not running as root and $XDG_RUNTIME_DIR is set, path will be set
+ to ``$XDG_RUNTIME_DIR/dpdk/<prefix>/config``
+ - if DPDK is not running as root and $XDG_RUNTIME_DIR is not set, path will be
+ set to ``/tmp/dpdk/<prefix>/config``
+
+* eal: both declaring and identifying devices will be streamlined in v18.08.
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.
- Functions previously deprecated will change or disappear:
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:
+ The following function is deprecated since 18.05, and will be removed
+ in 18.08:
- ``rte_eal_mbuf_default_mempool_ops``
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.
+* 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.
- 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: 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
* 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.
-* 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.
-
* pdump: As we changed to use generic IPC, some changes in APIs and structure
are expected in subsequent release.
* cryptodev: The following changes will be made in the library
for 18.08:
- - Removal of ``sym`` structure in ``rte_cryptodev_info`` structure,
- containing fields not relevant anymore since the session mempool
- is not internal in the crypto device anymore.
- - Replacement of ``pci_dev`` field with the more generic ``rte_device``
- structure.
- Functions ``rte_cryptodev_queue_pair_attach_sym_session()`` and
``rte_cryptodev_queue_pair_dettach_sym_session()`` will be deprecated from
18.05 and removed in 18.08, as there are no drivers doing anything useful
