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 the mempool cache memory if caching is not being used.**
|
|
|
|
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 the caching was always disabled
|
|
on these threads.
|
|
|
|
* **Changed the memory allocation scheme in the mempool library.**
|
|
|
|
* Added the ability to allocate a large mempool in fragmented virtual memory.
|
|
* Added new APIs to populate a mempool with memory.
|
|
* Added an API to free a mempool.
|
|
* Modified the API of the ``rte_mempool_obj_iter()`` function.
|
|
* Dropped the specific Xen Dom0 code.
|
|
* Dropped the specific anonymous mempool code in testpmd.
|
|
|
|
* **Added a 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.

|
|
driver.
|
|
|
|
* **Added mailbox interrupt support for ixgbe and igb VFs.**
|
|
|
|
When the physical NIC link comes up or down, the PF driver will send a
|
|
mailbox message to notify each VF. To handle this link up/down event,
|
|
support have been added for a mailbox interrupt to receive the message and
|
|
allow the application to register a callback for it.
|
|
|
|
* **Updated the ixgbe base driver.**
|
|
|
|
The ixgbe base driver was updated with changes including the
|
|

The enic driver was updated with changes including the following:
|
|
|
|
* Optimized the Tx function.
|
|
* Added Scattered Rx capability.
|
|
* Improved packet type identification.
|
|
* Added MTU update in non Scattered Rx mode and enabled MTU of up to 9208
|
|
with UCS Software release 2.2 on 1300 series VICs.
|
|
|
|
* **Updated the mlx5 driver.**
|
|
|
|
The mlx5 driver was updated with changes including the following:
|
|
|
|
* Data path was refactored to bypass Verbs to improve RX and TX performance.
|
|
* Removed compilation parameters for inline send, ``MLX5_MAX_INLINE``, and
|
|
added command line parameter instead, ``txq_inline``.
|
|
* Improved TX scatter gather support:
|
|
Removed compilation parameter ``MLX5_PMD_SGE_WR_N``.
|
|
Scatter-gather elements is set to the maximum value the NIC supports.
|
|
Removed linearization logic, this decreases the memory consumption of the PMD.
|
|
* Improved jumbo frames support, by dynamically setting RX scatter gather elements
|
|
according to the MTU and mbuf size,
|
|
no need for compilation parameter ``MLX5_PMD_SGE_WR_N``
|
|
|
|
* **Added support for virtio on IBM POWER8.**
|
|
|
|
The ioports are mapped in memory when using Linux UIO.
|
|
|
|
* **Added support for Virtio in 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.
|
|
* Doesn't work with ``--huge-unlink``.
|
|
* Doesn't work with ``--no-huge``.
|
|
* Doesn't work when there are more than ``VHOST_MEMORY_MAX_NREGIONS(8)`` hugepages.
|
|
* Root privilege is required for sorting hugepages by physical address.
|
|
* Can only be used with the vhost user backend.
|
|
|
|
* **Added vhost-user client mode.**
|
|
|
|
DPDK vhost-user now supports client mode as well as server mode. Client mode
|
|
is enabled when the ``RTE_VHOST_USER_CLIENT`` flag is set while calling
|
|
``rte_vhost_driver_register``.
|
|
|
|
When DPDK vhost-user restarts from an normal or abnormal exit (such as a
|
|
crash), the client mode allows DPDK to establish the connection again. Note
|
|
that QEMU version v2.7 or above is required for this feature.
|
|
|
|
DPDK vhost-user will also try to reconnect by default when:
|
|
|
|
* The first connect fails (for example when QEMU is not started yet).
|
|
* The connection is broken (for example when QEMU restarts).
|
|
|
|
It can be turned off by setting the ``RTE_VHOST_USER_NO_RECONNECT`` flag.
|
|
|
|
* **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 AES counter mode support 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 the
|
|
``rte_hash_add_key`` function.
|
|
* Changed the Cuckoo Hash Search algorithm to breadth first search for
|
|
multi-writer routines and split Cuckoo Hash Search and Move operations in
|
|
order to reduce transactional code region and improve TSX performance.
|
|
* Added a hash multi-writer test case to the test app.
|
|
|
|
* **Improved IP Pipeline Application.**
|
|
|
|
The following features have been added to the ip_pipeline application:
|
|
|
|
* Configure the MAC address in the routing pipeline and automatic route
|
|
updates with change in link state.
|
|
* Enable RSS per network interface through the configuration file.
|
|
* Streamline the CLI code.
|
|
|
|
* **Added keepalive enhancements.**
|
|
|
|
Added 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 a packet capture API.
|
|
* A new ``app/pdump`` tool is added to demonstrate 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.
|
|
|
|
* **Added support for live migration of a VM with SRIOV VF.**
|
|
|
|
Live migration of a VM with Virtio and VF PMD's using the bonding PMD.
|
|
|
|
|
|
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
|
|
~~~
|
|
|
|
* **igb_uio: Fixed possible mmap failure for Linux >= 4.5.**
|
|
|
|
The mmaping of the iomem range of the PCI device fails for kernels that
|
|
enabled the ``CONFIG_IO_STRICT_DEVMEM`` option. The error seen by the
|
|
user is as similar to the following::
|
|
|
|
EAL: pci_map_resource():
|
|
|
|
cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0):
|
|
Invalid argument (0xffffffffffffffff)
|
|
|
|
The ``CONFIG_IO_STRICT_DEVMEM`` kernel option was introduced in Linux v4.5.
|
|
|
|
The issues was resolve by updating ``igb_uio`` to stop reserving PCI memory
|
|
resources. From the kernel point of view the iomem region looks like idle
|
|
and mmap works again. This matches the ``uio_pci_generic`` usage.
|
|
|
|
|
|
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.
|
|
|
|
* **enic: Fixed several issues when stopping then restarting ports and queues.**
|
|
|
|
Fixed several crashes related to stopping then restarting ports and queues.
|
|
Fixed possible crash when re-configuring the number of Rx queue descriptors.
|
|
|
|
* **enic: Fixed Rx data mis-alignment if mbuf data offset modified.**
|
|
|
|
Fixed possible Rx corruption when mbufs were returned to a pool with data
|
|
offset other than RTE_PKTMBUF_HEADROOM.
|
|
|
|
* **enic: Fixed Tx IP/UDP/TCP checksum offload and VLAN insertion.**
|
|
|
|
* **enic: Fixed Rx error and missed counters.**
|
|
|
|
|
|
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. This lead to a memory leak of the direct mbuf.

|
|
|
.. 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 the ``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 described
|
|
below. It is 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.
|
|
|
|
* The script ``dpdk_nic_bind.py`` is renamed to ``dpdk-devbind.py``.
|
|
And the script ``setup.sh`` is renamed to ``dpdk-setup.sh``.
|
|
|
|
|
|
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 files.
|
|
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 the number of queues configured by software.
|
|
|
|
* A Vhost ABI refactoring has been made: the ``virtio_net`` structure is no
|
|
longer exported directly to the application. Instead, a handle, ``vid``, has
|
|
been used to represent this structure internally.
|
|
|
|
|
|
