+DPDK Release 16.04
+==================
+
+
+New Features
+------------
+
+* **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
+ to bulk allocate mbufs.
+
+* **Added device link speed capabilities.**
+
+ The structure ``rte_eth_dev_info`` now has a ``speed_capa`` bitmap, which
+ allows the application to determine the supported speeds of each device.
+
+* **Added bitmap of link speeds to advertise.**
+
+ Added a feature to allow the definition of a set of advertised speeds for auto-negotiation,
+ explicitly disabling link auto-negotiation (single speed)
+ and full auto-negotiation.
+
+* **Added new poll-mode driver for Amazon Elastic Network Adapters (ENA).**
+
+ The driver operates for a variety of ENA adapters through feature negotiation
+ with the adapter and upgradable commands set.
+ The ENA driver handles PCI Physical and Virtual ENA functions.
+
+* **Restored vmxnet3 TX data ring.**
+
+ TX data ring has been shown to improve small packet forwarding performance
+ on the vSphere environment.
+
+* **Added vmxnet3 TX L4 checksum offload.**
+
+ Added support for TCP/UDP checksum offload to vmxnet3.
+
+* **Added vmxnet3 TSO support.**
+
+ Added support for TSO to vmxnet3.
+
+* **Added vmxnet3 support for jumbo frames.**
+
+ Added support for linking multi-segment buffers together to
+ handle Jumbo packets.
+
+* **Enabled Virtio 1.0 support.**
+
+ 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 supports VFIO-noiommu mode only.
+ Virtio can work with other non-x86 architectures as well, like PowerPC.
+
+* **Supported Virtio offload in vhost-user.**
+
+ Added the offload and negotiation of checksum and TSO between vhost-user and
+ vanilla Linux Virtio guest.
+
+* **Added vhost-user live migration support.**
+
+* **Added vhost driver.**
+
+ Added a virtual PMD that wraps ``librte_vhost``.
+
+* **Added multicast promiscuous mode support on VF for ixgbe.**
+
+ Added multicast promiscuous mode support for the ixgbe VF driver so all VFs
+ can receive the multicast packets.
+
+ Please note if you want to use this promiscuous mode, you need both PF and VF
+ driver to support it. The reason is that this VF feature is configured in the PF.
+ If you use kernel PF driver and the dpdk VF driver, make sure the kernel PF driver supports
+ VF multicast promiscuous mode. If you use dpdk PF and dpdk VF ensure the PF
+ driver is the same version as the VF.
+
+* **Added support for E-tag on X550.**
+
+ E-tag is defined in `802.1BR - Bridge Port Extension <http://www.ieee802.org/1/pages/802.1br.html>`_.
+
+ This feature is for the VF, but the settings are on the PF. It means
+ the CLIs should be used on the PF, but some of their effects will be shown on the VF.
+ The forwarding of E-tag packets based on GRP and E-CID_base will have an effect
+ on the PF. Theoretically, the E-tag packets can be forwarded to any pool/queue
+ but normally we'd like to forward the packets to the pools/queues belonging
+ to the VFs. And E-tag insertion and stripping will have an effect on VFs. When
+ a VF receives E-tag packets it should strip the E-tag. When the VF transmits
+ packets, it should insert the E-tag. Both actions can be offloaded.
+
+ When we want to use this E-tag support feature, the forwarding should be
+ enabled to forward the packets received by the PF to the indicated VFs. And insertion
+ and stripping should be enabled for VFs to offload the effort to hardware.
+
+ Features added:
+
+ * Support E-tag offloading of insertion and stripping.
+ * Support Forwarding E-tag packets to pools based on
+ GRP and E-CID_base.
+
+* **Added support for VxLAN and NVGRE checksum off-load on X550.**
+
+ * Added support for VxLAN and NVGRE RX/TX checksum off-load on
+ X550. RX/TX checksum off-load is provided on both inner and
+ outer IP header and TCP header.
+ * Added functions to support VxLAN port configuration. The
+ default VxLAN port number is 4789 but this can be updated
+ programmatically.
+
+* **Added support for new X550EM_a devices.**
+
+ Added support for new X550EM_a devices and their MAC types, X550EM_a and X550EM_a_vf.
+ Updated the relevant PMD to use the new devices and MAC types.
+
+* **Added x550em_x V2 device support.**
+
+ Added support for x550em_x V2 device. Only x550em_x V1 was supported before.
+ A mask for V1 and V2 is defined and used to support both.
+
+* **Supported link speed auto-negotiation on X550EM_X**
+
+ Normally the auto-negotiation is supported by firmware and software doesn't care about
+ it. But on x550em_x, firmware doesn't support auto-negotiation. As the ports of x550em_x
+ are 10GbE, if we connect the port with a peer which is 1GbE, the link will always
+ be down.
+ We added the support for auto-negotiation by software to avoid this link down issue.
+
+* **Added software-firmware sync on X550EM_a.**
+
+ Added support for software-firmware sync for resource sharing.
+ Use the PHY token, shared between software-firmware for PHY access on X550EM_a.
+
+* **Updated the i40e base driver.**
+
+ The i40e base driver was updated with changes including the
+ following:
+
+ * Use RX control AQ commands to read/write RX control registers.
+ * Add new X722 device IDs, and removed X710 one was never used.
+ * Expose registers for HASH/FD input set configuring.
+
+* **Enabled PCI extended tag for i40e.**
+
+ Enabled extended tag for i40e by checking and writing corresponding PCI config
+ space bytes, to boost the performance.
+ The legacy method of reading/writing sysfile supported by kernel module igb_uio
+ is now deprecated.
+
+* **Added i40e support for setting mac addresses.**
+
+* **Added dump of i40e registers and EEPROM.**
+
+* **Supported ether type setting of single and double VLAN for i40e**
+
+* **Added VMDQ DCB mode in i40e.**
+
+ Added support for DCB in VMDQ mode to i40e driver.
+
+* **Added i40e VEB switching support.**
+
+* **Added Flow director enhancements in i40e.**

+
+ Only available with Mellanox OFED >= 3.2.
+
+* **Added mlx5 optional packet padding by HW.**
+
+ Added an option to make PCI bus transactions rounded to a multiple of a
+ cache line size for better alignment.
+
+ Only available with Mellanox OFED >= 3.2.
+
+* **Added mlx5 TX VLAN insertion support.**
+
+ Added support for TX VLAN insertion.
+
+ Only available with Mellanox OFED >= 3.2.
+
+* **Changed szedata2 driver type from vdev to pdev.**
+

+
+
+Resolved Issues
+---------------
+
+Drivers
+~~~~~~~
+
+* **ethdev: Fixed overflow for 100Gbps.**
+
+ 100Gbps in Mbps (100000) was exceeding the 16-bit max value of ``link_speed``
+ in ``rte_eth_link``.
+
+* **ethdev: Fixed byte order consistency between fdir flow and mask.**
+
+ Fixed issue in ethdev library where the structure for setting
+ fdir's mask and flow entry was not consistent in byte ordering.
+
+* **cxgbe: Fixed crash due to incorrect size allocated for RSS table.**
+
+ Fixed a segfault that occurs when accessing part of port 0's RSS
+ table that gets overwritten by subsequent port 1's part of the RSS
+ table due to incorrect size allocated for each entry in the table.
+
+* **cxgbe: Fixed setting wrong device MTU.**
+
+ Fixed an incorrect device MTU being set due to the Ethernet header and
+ CRC lengths being added twice.
+
+* **ixgbe: Fixed zeroed VF mac address.**
+
+ Resolved an issue where the VF MAC address is zeroed out in cases where the VF
+ driver is loaded while the PF interface is down.
+ The solution is to only set it when we get an ACK from the PF.
+
+* **ixgbe: Fixed setting flow director flag twice.**
+
+ Resolved an issue where packets were being dropped when switching to perfect
+ filters mode.
+
+* **ixgbe: Set MDIO speed after MAC reset.**
+
+ The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock
+ speed becomes invalid, therefore the driver reads invalid PHY register values.
+ The driver now set the MDIO clock speed prior to initializing PHY ops and
+ again after the MAC reset.
+
+* **ixgbe: Fixed maximum number of available TX queues.**
+
+ In IXGBE, the maximum number of TX queues varies depending on the NIC operating
+ mode. This was not being updated in the device information, providing
+ an incorrect number in some cases.
+
+* **i40e: Generated MAC address for each VFs.**
+
+ It generates a MAC address for each VFs during PF host initialization,
+ and keeps the VF MAC address the same among different VF launch.
+
+* **i40e: Fixed failure of reading/writing RX control registers.**
+
+ Fixed i40e issue of failing to read/write rx control registers when
+ under stress with traffic, which might result in application launch
+ failure.
+
+* **i40e: Enabled vector driver by default.**
+
+ Previously, vector driver was disabled by default as it couldn't fill packet type
+ info for l3fwd to work well. Now there is an option for l3fwd to analyze
+ the packet type so the vector driver is enabled by default.
+
+* **i40e: Fixed link info of VF.**
+
+ Previously, the VF's link speed stayed at 10GbE and status always was up.
+ It did not change even when the physical link's status changed.
+ Now this issue is fixed to make VF's link info consistent with physical link.
+
+* **mlx5: Fixed possible crash during initialization.**
+
+ A crash could occur when failing to allocate private device context.
+
+* **mlx5: Added port type check.**
+
+ Added port type check to prevent port initialization on non-Ethernet link layers and
+ to report an error.
+
+* **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.**
+
+ Prevented reception of multicast frames outside of configured VLANs.
+
+* **mlx5: Fixed RX checksum offload in non L3/L4 packets.**
+
+ Fixed report of bad checksum for packets of unknown type.
+
+* **aesni_mb: Fixed wrong return value when creating a device.**
+
+ The ``cryptodev_aesni_mb_init()`` function was returning the device id of the device created,
+ instead of 0 (on success) that ``rte_eal_vdev_init()`` expects.
+ This made it impossible to create more than one aesni_mb device
+ from the 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 a multiple of 4 bytes.
+
+* **hash: Fixed hash library to support multi-process mode.**
+
+ Fix hash library to support multi-process mode, using a jump table,
+ instead of storing a function pointer to the key compare function.
+ Multi-process mode only works with the built-in compare functions,
+ however a custom compare function (not in the jump table) can only
+ be used in single-process mode.
+
+* **hash: Fixed return value when allocating an existing hash table.**
+
+ Changed the ``rte_hash*_create()`` functions to return ``NULL`` and set
+ ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
+ the behavior described in the API documentation in the header file.
+ The previous behavior was to return a pointer to the existing object in
+ that case, preventing the caller from knowing if the object had to be freed
+ or not.
+
+* **lpm: Fixed return value when allocating an existing object.**
+
+ Changed the ``rte_lpm*_create()`` functions to return ``NULL`` and set
+ ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
+ the behavior described in the API documentation in the header file.
+ The previous behavior was to return a pointer to the existing object in
+ that case, preventing the caller from knowing if the object had to be freed
+ or not.
+
+* **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.**
+
+ Fixed core dump issue on txq and swq when dropless is set to yes.
+
+
+Examples
+~~~~~~~~
+
+* **l3fwd-power: Fixed memory leak for non-IP packet.**
+
+ Fixed issue in l3fwd-power where, on receiving packets of types
+ other than IPv4 or IPv6, the mbuf was not released, and caused
+ a memory leak.
+
+* **l3fwd: Fixed using packet type blindly.**
+
+ l3fwd makes use of packet type information without querying if devices or PMDs
+ really set it. For those devices that don't set ptypes, add an option to parse it.
+
+* **examples/vhost: Fixed frequent mbuf allocation failure.**
+
+ The vhost-switch often fails to allocate mbuf when dequeue from vring because it
+ wrongly calculates the number of mbufs needed.
+
+
+API Changes
+-----------
+
+* The ethdev statistics counter ``imissed`` is considered to be independent of ``ierrors``.
+ All drivers are now counting the missed packets only once, i.e. drivers will
+ not increment ierrors anymore for missed packets.
+
+* The ethdev structure ``rte_eth_dev_info`` was changed to support device
+ speed capabilities.
+
+* The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to
+ support the new link API.
+
+* The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
+ have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
+ ``rte_eth_dev_udp_tunnel_port_delete``.
+
+* The ``outer_mac`` and ``inner_mac`` fields in structure
+ ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
+ to keep code's readability.
+
+* The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
+ to be in big endian.
+
+* A parameter ``vlan_type`` has been added to the function
+ ``rte_eth_dev_set_vlan_ether_type``.
+
+* The af_packet device init function is no longer public. The device should be attached
+ via the API.
+
+* 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 the 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 RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
+ from 8-bit to 16-bit.
+
+* The ethdev flow director structure ``rte_eth_fdir_flow`` structure was
+ changed. New fields were added to extend flow director's input set.
+
+* The cmdline buffer size has been increase from 256 to 512.
