New Features
------------
.. This section should contain new features added in this release.
Sample format:
* **Add a title in the past tense with a full stop.**
Add a short 1-2 sentence description in the past tense.
The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.
* Enhanced feature bar to do something else.
Refer to the previous release notes for examples.

=========================================================
* **Added support for Hyper-V netvsc PMD.**
The new ``netvsc`` poll mode driver provides native support for
networking on Hyper-V. See the :doc:`../nics/netvsc` NIC driver guide
for more details on this new driver.
* **Added Flow API support for CXGBE PMD.**
Flow API support has been added to CXGBE Poll Mode Driver to offload
flows to Chelsio T5/T6 NICs. Support added for:
* Wildcard (LE-TCAM) and Exact (HASH) match filters.
* Match items: physical ingress port, IPv4, IPv6, TCP and UDP.
* Action items: queue, drop, count, and physical egress port redirect.
* **Added ixgbe preferred Rx/Tx parameters.**
Rather than applications providing explicit Rx and Tx parameters such as
queue and burst sizes, they can request that the EAL instead uses preferred
values provided by the PMD, falling back to defaults within the EAL if the
PMD does not provide any. The provision of such tuned values now includes
the ixgbe PMD.
* **Added descriptor status check support for fm10k.**
``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
are supported by fm10K.
* **Updated the enic driver.**
* Add low cycle count Tx handler for no-offload Tx.
* Add low cycle count Rx handler for non-scattered Rx.
* Minor performance improvements to scattered Rx handler.
* Add handlers to add/delete VxLAN port number.
* Add devarg to specify ingress VLAN rewrite mode.
* **Updated mlx5 driver.**
Updated the mlx5 driver including the following changes:
* Added port representors support.
* Added Flow API support for e-switch rules.
Supported ACTION_PORT_ID, ACTION_DROP, ACTION_OF_POP_VLAN,
ACTION_OF_PUSH_VLAN, ACTION_OF_SET_VLAN_VID, ACTION_OF_SET_VLAN_PCP
and ITEM_PORT_ID.
* Supported 32-bit compilation.
* **Added TSO support for mlx4 driver.**
The support is from MLNX_OFED_4.4 and above.
* **SoftNIC PMD rework.**
The SoftNIC PMD infrastructure is restructured to use the Packet Framework,
which makes it more flexible, modular and easier to add new functionality
in future.
* **Updated the AESNI MB PMD.**
The AESNI MB PMD has been updated with additional support for:
* 3DES for 8, 16 and 24 byte keys.
* **Added a new compression PMD using Intel's QuickAssist (QAT) device family.**
Added the new ``QAT`` compression driver, for compression and decompression
operations in software. See the :doc:`../compressdevs/qat_comp` compression
driver guide for details on this new driver.
* **Updated the ISA-L PMD.**
Added support for chained mbufs (input and output).
API Changes
-----------
.. This section should contain API changes. Sample format:
* Add a short 1-2 sentence description of the API change.
Use fixed width quotes for ``function_names`` or ``struct_names``.
Use the past tense.
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=========================================================
* Path to runtime config file has changed. The new path is determined as
follows:
- If DPDK is running as root, ``/var/run/dpdk/<prefix>/config``
- If DPDK is not running as root:
* If ``$XDG_RUNTIME_DIR`` is set, ``${XDG_RUNTIME_DIR}/dpdk/<prefix>/config``
* Otherwise, ``/tmp/dpdk/<prefix>/config``
* mempool: Following functions were deprecated and are removed in 18.08:
- ``rte_mempool_populate_iova_tab``
- ``rte_mempool_populate_phys_tab``
- ``rte_mempool_populate_phys`` (``rte_mempool_populate_iova`` should be used)
- ``rte_mempool_virt2phy`` (``rte_mempool_virt2iova`` should be used)
- ``rte_mempool_xmem_create``
- ``rte_mempool_xmem_size``
- ``rte_mempool_xmem_usage``
* ethdev: The old offload API is removed:
- Rx per-port ``rte_eth_conf.rxmode.[bit-fields]``
- Tx per-queue ``rte_eth_txconf.txq_flags``
- ``ETH_TXQ_FLAGS_NO*``
The transition bits are removed:
- ``rte_eth_conf.rxmode.ignore_offload_bitfield``
- ``ETH_TXQ_FLAGS_IGNORE``
* cryptodev: In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
has been replaced with field ``struct rte_device *device``.
Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
supports an unlimited number of sessions.
Two new fields of type ``uint16_t`` have been added:
``min_mbuf_headroom_req`` and ``min_mbuf_tailroom_req``.
These parameters specify the recommended headroom and tailroom for mbufs
to be processed by the PMD.
* cryptodev: Following functions were deprecated and are removed in 18.08:
- ``rte_cryptodev_queue_pair_start``
- ``rte_cryptodev_queue_pair_stop``
- ``rte_cryptodev_queue_pair_attach_sym_session``
- ``rte_cryptodev_queue_pair_detach_sym_session``
* cryptodev: Following functions were deprecated and are replaced by
other functions in 18.08:
- ``rte_cryptodev_get_header_session_size`` is replaced with
``rte_cryptodev_sym_get_header_session_size``
- ``rte_cryptodev_get_private_session_size`` is replaced with
``rte_cryptodev_sym_get_private_session_size``
* cryptodev: Feature flag ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` is
replaced with the following more explicit flags:
- ``RTE_CRYPTODEV_FF_IN_PLACE_SGL``
- ``RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT``
- ``RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT``
- ``RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT``
- ``RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT``
* cryptodev: Renamed cryptodev experimental APIs:
Used user_data instead of private_data in following APIs to avoid confusion
with the existing session parameter ``sess_private_data[]`` and related APIs.
- ``rte_cryptodev_sym_session_set_private_data()`` changed to
``rte_cryptodev_sym_session_set_user_data()``
- ``rte_cryptodev_sym_session_get_private_data()`` changed to
``rte_cryptodev_sym_session_get_user_data()``
* compressdev: Feature flag ``RTE_COMP_FF_MBUF_SCATTER_GATHER`` is
replaced with the following more explicit flags:
- ``RTE_COMP_FF_OOP_SGL_IN_SGL_OUT``
- ``RTE_COMP_FF_OOP_SGL_IN_LB_OUT``
- ``RTE_COMP_FF_OOP_LB_IN_SGL_OUT``
