Refer to the previous release notes for examples.
+* **Added function to check primary process state.**
+
+ A new function ``rte_eal_primary_proc_alive()`` has been added
+ to allow the user to detect if a primary process is running.
+ Use cases for this feature include fault detection, and monitoring
+ using secondary processes.
+
* **Enabled bulk allocation of mbufs.**
A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user
Enabled virtio 1.0 support for virtio pmd driver.
+* **Supported virtio for ARM.**
+
+ Enabled virtio support for armv7/v8. Tested for arm64.
+ Virtio for arm support VFIO-noiommu mode only.
+ Virtio can work with other non-x86 arch too like powerpc.
+
* **Supported virtio offload in vhost-user.**
Add the offload and negotiation of checksum and TSO between vhost-user and
* **Added vhost-user live migration support.**
+* **Enabled PCI extended tag for i40e.**
+
+ It enabled extended tag by checking and writing corresponding PCI config
+ space bytes, to boost the performance. In the meanwhile, it deprecated the
+ legacy way via reading/writing sysfile supported by kernel module igb_uio.
+
+* **Increased number of next hops for LPM IPv4 to 2^24.**
+
+ The next_hop field is extended from 8 bits to 24 bits for IPv4.
+
+* **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.**
+
+ Enabled support for SNOW 3G wireless algorithm for Intel Quick Assist devices.
+ Support for cipher only, hash only is also provided
+ along with alg-chaining operations.
+
+* **Added SNOW3G SW PMD.**
+
+ A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering
+ and SNOW3G UIA2 hashing.
+
+* **Added AES GCM PMD.**
+
+ Added new Crypto PMD to support AES-GCM authenticated encryption and
+ authenticated decryption in SW.
+
+* **Added NULL Crypto PMD**
+
+ Added new Crypto PMD to support null crypto operations in SW.
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.**
+* **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.
-* **examples/vhost: Fixed frequent mbuf allocation failure.**
-
- vhost-switch often fails to allocate mbuf when dequeue from vring because it
- wrongly calculates the number of mbufs needed.

+* **ethdev: Fixed byte order consistency between fdir flow and mask.**
+
+ Fixed issue in ethdev library that the structure for setting
+ fdir's mask and flow entry was not consistent in byte ordering.
+
* **aesni_mb: Fixed wrong return value when creating a device.**
cryptodev_aesni_mb_init() was returning the device id of the device created,
This made impossible the creation of more than one aesni_mb device
from command line.
+* **qat: Fixed AES GCM decryption.**
+
+ Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
+ due to incorrect IV setting.
+
Libraries
~~~~~~~~~
+* **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
+
+ Fix crc32c hash functions to return a valid crc32c value for data lengths
+ not multiple of 4 bytes.
+
Examples
~~~~~~~~
+* **examples/vhost: Fixed frequent mbuf allocation failure.**
+
+ vhost-switch often fails to allocate mbuf when dequeue from vring because it
+ wrongly calculates the number of mbufs needed.
+
+* **examples/ipsec-secgw: ipsec security gateway**
+
+ New application implementing an IPsec Security Gateway.
Other
~~~~~
* 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 fields in ethdev structure ``rte_eth_fdir_masks`` were changed
+ to be in big endian.
+
+* The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
+ while keeping ABI compatibility.
+
+* A new ``rte_lpm_config`` structure is used so LPM library will allocate
+ exactly the amount of memory which is necessary to hold application’s rules.
+ The previous ABI is kept for compatibility.
+
+* The prototype for the pipeline input port, output port and table action
+ handlers are updated: the pipeline parameter is added,
+ the packets mask parameter has been either removed or made input-only.
+
ABI Changes
-----------
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 RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
+ from 8-bit to 16-bit.
+
+* The cmdline buffer size has been increase from 256 to 512.
