==================
.. **Read this first.**
The text below explains how to update the release notes.
Use proper spelling, capitalization and punctuation in all sections.
Variable and config names should be quoted as fixed width text: ``LIKE_THIS``.
Build the docs and view the output file to ensure the changes are correct::
make doc-guides-html
firefox build/doc/html/guides/rel_notes/release_16_07.html
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.
* **Removed mempool cache if not needed.**
The size of the mempool structure is reduced if the per-lcore cache is disabled.
* **Added mempool external cache for non-EAL thread.**
Added new functions to create, free or flush a user-owned mempool
cache for non-EAL threads. Previously, cache was always disabled
on these threads.
* **Changed the memory allocation in mempool library.**
* Added ability to allocate a large mempool in virtually fragmented memory.
* Added new APIs to populate a mempool with memory.
* Added an API to free a mempool.
* Modified the API of rte_mempool_obj_iter() function.
* Dropped specific Xen Dom0 code.
* Dropped specific anonymous mempool code in testpmd.
* **Added new driver for Broadcom NetXtreme-C devices.**
Added the new bnxt driver for Broadcom NetXtreme-C devices. See the
"Network Interface Controller Drivers" document for more details on this
new driver.
* **Added new driver for ThunderX nicvf device.**
* **Added mailbox interrupt support for ixgbe and igb VFs.**
When the physical NIC link comes down or up, the PF driver will send a
mailbox message to notify each VF. To handle this link up/down event,
add mailbox interrupts support to receive the message and allow the app to
register a callback for it.
* **Updated the ixgbe base driver.**
The ixgbe base driver was updated with changes including the
following:
* Added sgmii link for X550.
* Added mac link setup for X550a SFP and SFP+.
* Added KR support for X550em_a.
* Added new phy definitions for M88E1500.
* Added support for the VLVF to be bypassed when adding/removing a VFTA entry.
* Added X550a flow control auto negotiation support.
* **Updated the i40e base driver.**
Updated the i40e base driver, which includes support for new devices IDs.
* **Supported virtio on IBM POWER8.**
The ioports are mapped in memory when using Linux UIO.
* **Virtio support for containers.**
Add a new virtual device, named virtio-user, to support virtio for containers.
Known limitations:
* Control queue and multi-queue are not supported yet.
* Cannot work with --huge-unlink.
* Cannot work with --no-huge.
* Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8) hugepages.
* Root privilege is a must for sorting hugepages by physical address.
* Can only be used with vhost user backend.
* **Added vhost-user client mode.**
DPDK vhost-user could be the server as well as the client. It supports
server mode only before, now it also supports client mode. Client mode
is enabled when ``RTE_VHOST_USER_CLIENT`` flag is set while calling
``rte_vhost_driver_register``.
When DPDK vhost-user restarts from normal or abnormal quit (say crash),
the client mode would allow DPDK to establish the connect again. Note
that a brand new QEMU version (v2.7 or above) is needed, otherwise, the
reconnect won't work.
DPDK vhost-user will also try to reconnect by default when
* the first connect fails (when QEMU is not started yet)
* the connection is broken (when QEMU restarts)
It can be turned off if flag ``RTE_VHOST_USER_NO_RECONNECT`` is set.
* **Added NSH packet recognition in i40e.**
* **Added AES-CTR support to AESNI MB PMD.**
Now AESNI MB PMD supports 128/192/256-bit counter mode AES encryption and
decryption.
* **Added support of AES counter mode for Intel QuickAssist devices.**
Enabled support for the AES CTR algorithm for Intel QuickAssist devices.
Provided support for algorithm-chaining operations.
* **Added KASUMI SW PMD.**
A new Crypto PMD has been added, which provides KASUMI F8 (UEA1) ciphering
and KASUMI F9 (UIA1) hashing.
* **Added multi-writer support for RTE Hash with Intel TSX.**
The following features/modifications have been added to rte_hash library:
* Enabled application developers to use an extra flag for rte_hash creation
to specify default behavior (multi-thread safe/unsafe) with rte_hash_add_key
function.
* Changed Cuckoo search algorithm to breadth first search for multi-writer
routine and split Cuckoo Search and Move operations in order to reduce
transactional code region and improve TSX performance.
* Added a hash multi-writer test case for test app.
* **Improved IP Pipeline Application.**
The following features have been added to ip_pipeline application:
* Configure the MAC address in the routing pipeline and automatic routes
updates with change in link state.
* Enable RSS per network interface through the configuration file.
* Streamline the CLI code.
* **Added keepalive enhancements.**
Adds support for reporting of core states other than dead to
monitoring applications, enabling the support of broader liveness
reporting to external processes.
* **Added packet capture framework.**
* A new library ``librte_pdump`` is added to provide packet capture API.
* A new ``app/pdump`` tool is added to capture packets in DPDK.
* **Added floating VEB support for i40e PF driver.**
A "floating VEB" is a special Virtual Ethernet Bridge (VEB) which does not
have an upload port, but instead is used for switching traffic between
virtual functions (VFs) on a port.
For information on this feature, please see the "I40E Poll Mode Driver"
section of the "Network Interface Controller Drivers" document.
Resolved Issues
---------------
.. This section should contain bug fixes added to the relevant sections. Sample format:
* **code/section Fixed issue in the past tense with a full stop.**
Add a short 1-2 sentence description of the resolved issue in the past tense.
The title should contain the code/lib section like a commit message.
Add the entries in alphabetic order in the relevant sections below.
EAL
~~~
Drivers
~~~~~~~
* **i40e: Fixed vlan stripping from inner header.**
Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan
tags of the inner header will be stripped without putting vlan
info to descriptor.
Now this issue is fixed by disabling vlan stripping from inner header.
* **i40e: Fixed the type issue of a single VLAN type.**
Currently, if a single VLAN header is added in a packet, it's treated
as inner VLAN. But generally, a single VLAN header is treated as the
outer VLAN header.
This issue is fixed by changing corresponding register for single VLAN.
Libraries
~~~~~~~~~
* **mbuf: Fixed refcnt update when detaching.**
Fix the ``rte_pktmbuf_detach()`` function to decrement the direct
mbuf's reference counter. The previous behavior was not to affect
the reference counter. It lead a memory leak of the direct mbuf.
Examples
~~~~~~~~
Other
~~~~~
Known Issues
------------
.. This section should contain new known issues in this release. Sample format:
* **Add title in present tense with full stop.**
Add a short 1-2 sentence description of the known issue in the present
tense. Add information on any known workarounds.
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 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
* The following counters are removed from ``rte_eth_stats`` structure:
ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff.
* The extended statistics are fetched by ids with ``rte_eth_xstats_get``
after a lookup by name ``rte_eth_xstats_get_names``.
* The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues``
and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``.
* The vhost function ``rte_vring_available_entries`` is renamed to
``rte_vhost_avail_entries``.
* All existing vhost APIs and callbacks with ``virtio_net`` struct pointer
as the parameter have been changed due to the ABI refactoring mentioned
below: it's replaced by ``int vid``.
* The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing
packets to the same queue.
* The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which
indicates the operation is forbidden because the port is running.
ABI Changes
-----------
.. * Add a short 1-2 sentence description of the ABI change that was announced in
the previous releases and made in this release. Use fixed width quotes for
``rte_function_names`` or ``rte_struct_names``. Use the past tense.
* The ``rte_port_source_params`` structure has new fields to support PCAP file.
It was already in release 16.04 with ``RTE_NEXT_ABI`` flag.
* The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues``
to support number of queues configured by software.
* vhost ABI refactoring has been made: ``virtio_net`` structure is never
exported to application any more. Instead, a handle, ``vid``, has been
used to represent this structure internally.
