New Features
------------
-* TODO.
+* **Enabled cloning of indirect mbufs.**
+
+ This feature removes a limitation of ``rte_pktmbuf_attach()`` which
+ generated the warning: "mbuf we're attaching to must be direct".
+
+ Now, when attaching to an indirect mbuf it is possible to:
+
+ * Copy all relevant fields (address, length, offload, ...) as before.
+
+ * Get the pointer to the mbuf that embeds the data buffer (direct mbuf),
+ and increase the reference counter.
+
+ When detaching the mbuf, we can now retrieve this direct mbuf as the
+ pointer is determined from the buffer address.
+
+
+* **Extended packet type support.**
+
+ In previous releases mbuf packet types were indicated by 6 bits in the
+ ``ol_flags``. This was not enough for some supported NICs. For example i40e
+ hardware can recognize more than 150 packet types. Not being able to
+ identify these additional packet types limits access to hardware offload
+ capabilities
+
+ So an extended "unified" packet type was added to support all possible
+ PMDs. The 16 bit packet_type in the mbuf structure was changed to 32 bits
+ and used for this purpose.
+
+ To avoid breaking ABI compatibility, the code changes this feature are
+ enclosed in a ``RTE_NEXT_ABI`` ifdef. This is enabled by default but can be
+ turned off for ABI compatibility with DPDK R2.0.
+
+
+* **Reworked memzone to be allocated by malloc and also support freeing.**
+
+ In the memory hierarchy, memsegs are groups of physically contiguous
+ hugepages, memzones are slices of memsegs, and malloc slices memzones
+ into smaller memory chunks.
+
+ This feature modifies ``malloc()`` so it partitions memsegs instead of
+ memzones. Now memzones allocate their memory from the malloc heap.
+
+ Backward compatibility with API and ABI are maintained.
+
+ This also memzones, and any other structure based on memzones, for example
+ mempools, to be freed. Currently only the API from freeing memzones is
+ supported.
+
+
+* **Interrupt mode PMD.**
+
+ This feature introduces a low-latency one-shot RX interrupt into DPDK. It
+ also adds a polling and interrupt mode switch control example.
+
+ DPDK userspace interrupt notification and handling mechanism is based on
+ UIO/VFIO with the following limitations:
+
+ * Per queue RX interrupt events are only allowed in VFIO which supports
+ multiple MSI-X vectors.
+ * In UIO, the RX interrupt shares the same vector with other
+ interrupts. When the RX interrupt and LSC interrupt are both enabled, only
+ the former is available.
+ * RX interrupt is only implemented for the linuxapp target.
+ * The feature is only currently enabled for tow PMDs: ixgbe and igb.
+
+
+* **Packet Framework enhancements.**
+
+ Several enhancements were made to the Packet Framework:
+
+ * A new configuration file syntax has been introduced for IP pipeline
+ applications. Parsing of the configuration file is changed.
+ * Implementation of the IP pipeline application is modified to make it more
+ structured and user friendly.
+ * Implementation of the command line interface (CLI) for each pipeline type
+ has been moved to the separate compilation unit. Syntax of pipeline CLI
+ commands has been changed.
+ * Initialization of IP pipeline is modified to match the new parameters
+ structure.
+ * New implementation of pass-through pipeline, firewall pipeline, routing
+ pipeline, and flow classification has been added.
+ * Master pipeline with CLI interface has been added.
+ * Added extended documentation of the IP Pipeline.
+
+
+* **Added API for IEEE1588 timestamping.**
+
+ This feature adds an ethdev API to enable, disable and read IEEE1588/802.1AS
+ PTP timestamps from devices that support it. The following functions were
+ added:
+
+ * ``rte_eth_timesync_enable()``
+ * ``rte_eth_timesync_disable()``
+ * ``rte_eth_timesync_read_rx_timestamp()``
+ * ``rte_eth_timesync_read_tx_timestamp()``
+
+ The "ieee1588" forwarding mode in testpmd was also refactored to demonstrate
+ the new API.
+
+
+* **Added multicast address filtering.**
+
+ Added multicast address filtering via a new ethdev function
+ ``set_mc_addr_list()``.
+
+ This overcomes a limitation in previous releases where the receipt of
+ multicast packets on a given port could only be enabled by invoking the
+ ``rte_eth_allmulticast_enable()`` function. This method did not work for VFs
+ in SR-IOV architectures when the host PF driver does not allow these
+ operation on VFs. In such cases, joined multicast addresses had to be added
+ individually to the set of multicast addresses that are filtered by the [VF]
+ port.
+
+
+* **Added Flow Director extensions.**
+
+ Several Flow Director extensions were added such as:
+
+ * Support for RSS and Flow Director hashes in vector RX.
+ * Added Flow Director for L2 payload.
+
+
+* **Added RSS hash key size query per port.**
+
+ This feature supports querying the RSS hash key size of each port. A new
+ field ``hash_key_size`` has been added in the ``rte_eth_dev_info`` struct
+ for storing hash key size in bytes.
+
+
+* **Added userspace ethtool support.**
+
+ Added userspace ethtool support to provide a familiar interface for
+ applications that manage devices via kernel-space ``ethtool_op`` and
+ ``net_device_op``.
+
+ The initial implementation focuses on operations that can be implemented
+ through existing ``netdev`` APIs. More operations will be supported in later
+ releases.
+
+
+* **Updated the ixgbe base driver.**
+
+ The ixgbe base driver was updated with several changes including the
+ following:
+
+ * Added a new 82599 device id.
+ * Added new X550 PHY ids.
+ * Added SFP+ dual-speed support.
+ * Added wait helper for X550 IOSF accesses.
+ * Added X550em features.
+ * Added X557 PHY LEDs support.
+ * Commands for flow director.
+ * Issue firmware command when resetting X550em.
+
+ See the git log for full details of the ixgbe/base changes.
+
+
+* **Added additional hotplug support.**
+
+ Port hotplug support was added to the following PMDs:
+
+ * e1000/igb.
+ * ixgbe.
+ * i40e.
+ * fm10k.
+ * Ring.
+ * Bonding.
+ * Virtio.
+
+ Port hotplug support was added to BSD.
+
+
+* **Added ixgbe LRO support.**
+
+ Added LRO support for x540 and 82599 devices.
+
+
+* **Added extended statistics for ixgbe.**
+
+ Implemented ``xstats_get()`` and ``xstats_reset()`` in dev_ops for
+ ixgbe to expose detailed error statistics to DPDK applications.
+
+ These will be implemented for other PMDs in later releases.
+
+
+* **Added proc_info application.**
+
+ Created a new ``proc_info`` application, by refactoring the existing
+ ``dump_cfg`` application, to demonstrate the usage of retrieving statistics,
+ and the new extended statistics (see above), for DPDK interfaces.
+
+
+* **Updated the i40e base driver.**
+
+ The i40e base driver was updated with several changes including the
+ following:
+
+ * Support for building both PF and VF driver together.
+ * Support for CEE DCBX on recent firmware versions.
+ * Replacement of ``i40e_debug_read_register()``.
+ * Rework of ``i40e_hmc_get_object_va``.
+ * Update of shadow RAM read/write functions.
+ * Enhancement of polling NVM semaphore.
+ * Enhancements on adminq init and sending asq command.
+ * Update of get/set LED functions.
+ * Addition of AOC phy types to case statement in get_media_type.
+ * Support for iSCSI capability.
+ * Setting of FLAG_RD when sending driver version to FW.
+
+ See the git log for full details of the i40e/base changes.
+
+
+* **Added support for port mirroring in i40e.**
+
+ Enabled mirror functionality in the i40e driver.
+
+
+* **Added support for i40e double VLAN, QinQ, stripping and insertion.**
+
+ Added support to the i40e driver for offloading double VLAN (QinQ) tags to
+ the mbuf header, and inserting double vlan tags by hardware to the packets
+ to be transmitted. Added a new field ``vlan_tci_outer`` in the ``rte_mbuf``
+ struct, and new flags in ``ol_flags`` to support this feature.
+
+
+
+* **Added fm10k promiscuous mode support.**
+
+ Added support for promiscuous/allmulticast enable and disable in the fm10k PF
+ function. VF is not supported yet.
+
+
+* **Added fm10k jumbo frame support.**
+
+ Added support for jumbo frame less than 15K in both VF and PF functions in the
+ fm10k pmd.
+
+
+* **Added fm10k mac vlan filtering support.**
+
+ Added support for the fm10k MAC filter, only available in PF. Updated the
+ VLAN filter to add/delete one static entry in the MAC table for each
+ combination of VLAN and MAC address.
+
+
+* **Added support for the Broadcom bnx2x driver.**
+
+ Added support for the Broadcom NetXtreme II bnx2x driver.
+
+
+* **Added support for the Chelsio CXGBE driver.**
+
+ Added support for the CXGBE Poll Mode Driver for the Chelsio Terminator 5
+ series of 10G/40G adapters.
+
+
+* **Enabled VMXNET3 vlan filtering.**
+
+ Added support for the VLAN filter functionality of the VMXNET3 interface.
+
+
+* **Added support for vhost live migration.**
+
+ Added support to allow live migration of vhost. Without this feature, qemu
+ will report the following error: "migrate: Migration disabled: vhost lacks
+ VHOST_F_LOG_ALL feature".
+
+
+* **Added support for pcap jumbo frames.**
+
+ Extended the PCAP PMD to support jumbo frames for RX and TX.
+
+
+* **Added support for the TILE-Gx architecture.**
+
+ Added support for the EZchip TILE-Gx family of SoCs.
+
+
+* **Added hardware memory transactions/lock elision for x86.**
+
+ Added the use of hardware memory transactions (HTM) on fast-path for rwlock
+ and spinlock (a.k.a. lock elision). The methods are implemented for x86
+ using Restricted Transactional Memory instructions (Intel(r) Transactional
+ Synchronization Extensions). The implementation fall-backs to the normal
+ rwlock if HTM is not available or memory transactions fail. This is not a
+ replacement for all rwlock usages since not all critical sections protected
+ by locks are friendly to HTM. For example, an attempt to perform a HW I/O
+ operation inside a hardware memory transaction always aborts the transaction
+ since the CPU is not able to roll-back should the transaction
+ fail. Therefore, hardware transactional locks are not advised to be used
+ around ``rte_eth_rx_burst()`` and ``rte_eth_tx_burst()`` calls.
+
+
+* **Updated Jenkins Hash function**
+
+ Updated the version of the Jenkins Hash (jhash) function used in DPDK from
+ the 1996 version to the 2006 version. This gives up to 35% better
+ performance, compared to the original one.
+
+ Note, the hashes generated by the updated version differ from the hashes
+ generated by the previous version.
+
+
+* **Added software implementation of the Toeplitz RSS hash**
+
+ Added a software implementation of the Toeplitz hash function used by RSS. It
+ can be used either for packet distribution on a single queue NIC or for
+ simulating RSS computation on a specific NIC (for example after GRE header
+ de-encapsulation).
+
+
+* **Replaced the existing hash library with a Cuckoo hash implementation.**
+
+ Replaced the existing hash library with another approach, using the Cuckoo
+ Hash method to resolve collisions (open addressing). This method pushes
+ items from a full bucket when a new entry must be added to it, storing the
+ evicted entry in an alternative location, using a secondary hash function.
+
+ This gives the user the ability to store more entries when a bucket is full,
+ in comparison with the previous implementation.
+
+ The API has not been changed, although new fields have been added in the
+ ``rte_hash`` structure, which has been changed to internal use only.
+
+ The main change when creating a new table is that the number of entries per
+ bucket is now fixed, so its parameter is ignored now (it is still there to
+ maintain the same parameters structure).
+
+ Also, the maximum burst size in lookup_burst function hash been increased to
+ 64, to improve performance.
+
+
+* **Optimized KNI RX burst size computation.**
+
+ Optimized KNI RX burst size computation by avoiding checking how many
+ entries are in ``kni->rx_q`` prior to actually pulling them from the fifo.
+
+
+* **Added KNI multicast.**
+
+ Enabled adding multicast addresses to KNI interfaces by adding an empty
+ callback for ``set_rx_mode`` (typically used for setting up hardware) so
+ that the ioctl succeeds. This is the same thing as the Linux tap interface
+ does.
+
+
+* **Added cmdline polling mode.**
+
+ Added the ability to process console input in the same thread as packet
+ processing by using the ``poll()`` function.
+
+* **Added VXLAN Tunnel End point sample application.**
+
+ Added a Tunnel End point (TEP) sample application that simulates a VXLAN
+ Tunnel Endpoint (VTEP) termination in DPDK. It is used to demonstrate the
+ offload and filtering capabilities of Intel XL710 10/40 GbE NICsfor VXLAN
+ packets.
+
+
+* **Enabled combining of the ``-m`` and ``--no-huge`` EAL options.**
+
+ Added option to allow combining of the ``-m`` and ``--no-huge`` EAL command
+ line options.
+
+ This allows user application to run as non-root but with higher memory
+ allocations, and removes a constraint on ``--no-huge`` mode being limited to
+ 64M.
+
Resolved Issues
---------------
-* TODO.
+* **acl: Fix ambiguity between test rules.**
+
+ Some test rules had equal priority for the same category. That could cause
+ an ambiguity in building the trie and test results.
+
+
+* **acl: Fix invalid rule wildness calculation for bitmask field type.**
+
+
+* **acl: Fix matching rule.**
+
+
+* **acl: Fix unneeded trie splitting for subset of rules.**
+
+ When rebuilding a trie for limited rule-set, don't try to split the rule-set
+ even further.
+
+
+* **app/testpmd: Fix crash when port id out of bound.**
+
+ Fixed issues in testpmd where using a port greater than 32 would cause a seg
+ fault.
+
+ Fixes: edab33b1c01d ("app/testpmd: support port hotplug")
+
+
+* **app/testpmd: Fix reply to a multicast ICMP request.**
+
+ Set the IP source and destination addresses in the IP header of the ICMP
+ reply.
+
+
+* **app/testpmd: fix MAC address in ARP reply.**
+
+ Fixed issue where in the ``icmpecho`` forwarding mode, ARP replies from
+ testpmd contain invalid zero-filled MAC addresses.
+
+ Fixes: 31db4d38de72 ("net: change arp header struct declaration")
+
+
+* **app/testpmd: fix default flow control values.**
+
+ Fixes: 422a20a4e62d ("app/testpmd: fix uninitialized flow control variables")
+
+
+* **bonding: Fix crash when stopping inactive slave.**
+
+
+* **bonding: Fix device initialization error handling.**
+
+
+* **bonding: Fix initial link status of slave.**
+
+ On Fortville NIC, link status change interrupt callback was not executed
+ when slave in bonding was (re-)started.
+
+
+* **bonding: Fix socket id for LACP slave.**
+
+ Fixes: 46fb43683679 ("bond: add mode 4")
+
+
+* **bonding: Fix device initialization error handling.**
+
+
+* **cmdline: Fix small memory leak.**
+
+ A function in ``cmdline.c`` had a return that did not free the buf properly.
+
+
+* **config: Enable same drivers options for Linux and BSD.**
+
+ Enabled vector ixgbe and i40e bulk alloc for BSD as it is already done for
+ Linux.
+
+ Fixes: 304caba12643 ("config: fix bsd options")
+ Fixes: 0ff3324da2eb ("ixgbe: rework vector pmd following mbuf changes")
+
+
+* **devargs: Fix crash on failure.**
+
+ This problem occurred when passing an invalid PCI id to the blacklist API in
+ devargs.
+
+
+* **e1000/i40e: Fix descriptor done flag with odd address.**
+
+
+* **e1000/igb: fix ieee1588 timestamping initialization.**
+
+ Fixed issue with e1000 ieee1588 timestamp initialization. On initialization
+ the IEEE1588 functions read the system time to set their timestamp. However,
+ on some 1G NICs, for example, i350, system time is disabled by default and
+ the IEEE1588 timestamp was always 0.
+
+
+* **eal/Linux: Fix irq handling with igb_uio.**
+
+ Fixed an issue where the the introduction of ``uio_pci_generic`` broke
+ interrupt handling with igb_uio.
+
+ Fixes: c112df6875a5 ("eal/Linux: toggle interrupt for uio_pci_generic")
+
+
+* **eal/bsd: Fix inappropriate header guards.**
+
+
+* **eal/bsd: Fix virtio on FreeBSD.**
+
+ Closing the ``/dev/io`` fd caused a SIGBUS in inb/outb instructions as the
+ process lost the IOPL privileges once the fd is closed.
+
+ Fixes: 8a312224bcde ("eal/bsd: fix fd leak")
+
+
+* **eal/linux: Fix comments on vfio MSI.**
+
+
+* **eal/linux: Fix numa node detection.**
+
+
+* **eal/linux: Fix socket value for undetermined numa node.**
+
+ Sets zero as the default value of pci device numa_node if the socket could
+ not be determined. This provides the same default value as FreeBSD which has
+ no NUMA support, and makes the return value of ``rte_eth_dev_socket_id()``
+ be consistent with the API description.
+
+
+* **eal/ppc: Fix cpu cycle count for little endian.**
+
+ On IBM POWER8 PPC64 little endian architecture, the definition of tsc union
+ will be different. This fix enables the right output from ``rte_rdtsc()``.
+
+
+* **ethdev: Fix check of threshold for TX freeing.**
+
+ Fixed issue where the parameter to ``tx_free_thresh`` was not consistent
+ between the drivers.
+
+
+* **ethdev: Fix crash if malloc of user callback fails.**
+
+ If ``rte_zmalloc()`` failed in ``rte_eth_dev_callback_register`` then the
+ NULL pointer would be dereferenced.
+
+
+* **ethdev: Fix illegal port access.**
+
+ To obtain a detachable flag, ``pci_drv`` is accessed in
+ ``rte_eth_dev_is_detachable()``. However ``pci_drv`` is only valid if port
+ is enabled. Fixed by checking ``rte_eth_dev_is_valid_port()`` first.
+
+
+* **ethdev: Make tables const.**
+
+
+* **ethdev: Rename and extend the mirror type.**
+
+
+* **examples/distributor: Fix debug macro.**
+
+ The macro to turn on additional debug output when the app was compiled with
+ ``-DDEBUG`` was broken.
+
+ Fixes: 07db4a975094 ("examples/distributor: new sample app")
+
+
+* **examples/kni: Fix crash on exit.**
+
+
+* **examples/vhost: Fix build with debug enabled.**
+
+ Fixes: 72ec8d77ac68 ("examples/vhost: rework duplicated code")
+
+
+* **fm10k: Fix RETA table initialization.**
+
+ The fm10k driver has 128 RETA entries in 32 registers, but it only
+ initialized the first 32 when doing multiple RX queue configurations. This
+ fix initializes all 128 entries.
+
+
+* **fm10k: Fix RX buffer size.**
+
+
+* **fm10k: Fix TX multi-segment frame.**
+
+
+* **fm10k: Fix TX queue cleaning after start error.**
+
+

+
+* **fm10k: Fix jumbo frame issue.**
+
+
+* **fm10k: Fix mac/vlan filtering.**
+
+
+* **fm10k: Fix maximum VF number.**
+
+
+* **fm10k: Fix maximum queue number for VF.**
+
+ Both PF and VF shared code in function ``fm10k_stats_get()``. The function
+ worked with PF, but had problems with VF since it has less queues than PF.
+
+ Fixes: a6061d9e7075 ("fm10k: register PF driver")
+
+
+* **fm10k: Fix queue disabling.**
+
+
+* **fm10k: Fix switch synchronization.**
+
+

+
+
+* **ixgbe/base: Fix tunneled UDP and TCP frames in flow director.**
+
+
+* **ixgbe: Check mbuf refcnt when clearing a ring.**
+
+ The function to clear the TX ring when a port was being closed, e.g. on exit
+ in testpmd, was not checking the mbuf refcnt before freeing it. Since the
+ function in the vector driver to clear the ring after TX does not setting
+ the pointer to NULL post-free, this caused crashes if mbuf debugging was
+ turned on.
+
+
+* **ixgbe: Fix RX with buffer address not word aligned.**
+
+ Niantic HW expects the Header Buffer Address in the RXD must be word
+ aligned.
+
+
+* **ixgbe: Fix RX with buffer address not word aligned.**
+
+
+* **ixgbe: Fix Rx queue reset.**
+
+ Fix to reset vector related RX queue fields to their initial values.
+
+ Fixes: c95584dc2b18 ("ixgbe: new vectorized functions for Rx/Tx")
+
+
+* **ixgbe: Fix TSO in IPv6.**
+
+ When TSO was used with IPv6, the generated frames were incorrect. The L4
+ frame was OK, but the length field of IPv6 header was not populated
+ correctly.
+
+
+* **ixgbe: Fix X550 flow director check.**
+
+
+* **ixgbe: Fix check for split packets.**
+
+ The check for split packets to be reassembled in the vector ixgbe PMD was
+ incorrectly only checking the first 16 elements of the array instead of
+ all 32.

+ Fixes: cf4b4708a88a ("ixgbe: improve slow-path perf with vector scattered Rx")
+
+
+* **ixgbe: Fix data access on big endian cpu.**

+* **ixgbe: Fix offload config option name.**
+
+ The RX_OLFLAGS option was renamed from DISABLE to ENABLE in the driver code
+ and Linux config. It is now renamed also in the BSD config and
+ documentation.
+
+ Fixes: 359f106a69a9 ("ixgbe: prefer enabling olflags rather than not disabling")
+
+
+* **ixgbe: Fix release queue mbufs.**
+
+ The calculations of what mbufs were valid in the RX and TX queues were
+ incorrect when freeing the mbufs for the vector PMD. This led to crashes due
+ to invalid reference counts when mbuf debugging was turned on, and possibly
+ other more subtle problems (such as mbufs being freed when in use) in other
+ cases.
+
+
+ Fixes: c95584dc2b18 ("ixgbe: new vectorized functions for Rx/Tx")
+
+
+* **ixgbe: Move PMD specific fields out of base driver.**
+
+ Move ``rx_bulk_alloc_allowed`` and ``rx_vec_allowed`` from ``ixgbe_hw`` to
+ ``ixgbe_adapter``.
+
+ Fixes: 01fa1d6215fa ("ixgbe: unify Rx setup")
+
+
+* **ixgbe: Rename TX queue release function.**
+
+
+* **ixgbevf: Fix RX function selection.**
+
+ The logic to select ixgbe the VF RX function is different than the PF.
+
+
+* **ixgbevf: Fix link status for PF up/down events.**
+
+
+* **kni: Fix RX loop limit.**
+
+ Loop processing packets dequeued from rx_q was using the number of packets
+ requested, not how many it actually received.
+
+
+* **kni: Fix ioctl in containers, like Docker.**
+
+
+* **kni: Fix multicast ioctl handling.**
+
+
+* **log: Fix crash after log_history dump.**
+
+
+* **lpm: Fix big endian support.**
+
+
+* **lpm: Fix depth small entry add.**
+
+
+* **mbuf: Fix cloning with private mbuf data.**
+
+ Added a new ``priv_size`` field in mbuf structure that should be initialized
+ at mbuf pool creation. This field contains the size of the application
+ private data in mbufs.
+
+ Introduced new static inline functions ``rte_mbuf_from_indirect()`` and
+ ``rte_mbuf_to_baddr()`` to replace the existing macros, which take the
+ private size into account when attaching and detaching mbufs.
+
+
+* **mbuf: Fix data room size calculation in pool init.**
+
+ Deduct the mbuf data room size from ``mempool->elt_size`` and ``priv_size``,
+ instead of using an hardcoded value that is not related to the real buffer
+ size.
+
+ To use ``rte_pktmbuf_pool_init()``, the user can either:
+
+ * Give a NULL parameter to rte_pktmbuf_pool_init(): in this case, the
+ private size is assumed to be 0, and the room size is ``mp->elt_size`` -
+ ``sizeof(struct rte_mbuf)``.
+ * Give the ``rte_pktmbuf_pool_private`` filled with appropriate
+ data_room_size and priv_size values.
+
+
+* **mbuf: Fix init when private size is not zero.**
+
+ Allow the user to use the default ``rte_pktmbuf_init()`` function even if
+ the mbuf private size is not 0.
+
+
+* **mempool: Add structure for object headers.**
+
+ Each object stored in mempools are prefixed by a header, allowing for
+ instance to retrieve the mempool pointer from the object. When debug is
+ enabled, a cookie is also added in this header that helps to detect
+ corruptions and double-frees.
+
+ Introduced a structure that materializes the content of this header,
+ and will simplify future patches adding things in this header.
+
+
+* **mempool: Fix pages computation to determine number of objects.**
+
+
+* **mempool: Fix returned value after counting objects.**
+
+ Fixes: 148f963fb532 ("xen: core library changes")
+
+
+* **mlx4: Avoid requesting TX completion events to improve performance.**
+
+ Instead of requesting a completion event for each TX burst, request it on a
+ fixed schedule once every MLX4_PMD_TX_PER_COMP_REQ (currently 64) packets to
+ improve performance.
+
+
+* **mlx4: Fix possible crash on scattered mbuf allocation failure.**
+
+ Fixes issue where failing to allocate a segment, ``mlx4_rx_burst_sp()``
+ could call ``rte_pktmbuf_free()`` on an incomplete scattered mbuf whose next
+ pointer in the last segment is not set.
+
+
+* **mlx4: Fix support for multiple vlan filters.**
+
+ This fixes the "Multiple RX VLAN filters can be configured, but only the
+ first one works" bug.
+
+
+* **pcap: Fix storage of name and type in queues.**
+
+ pcap_rx_queue/pcap_tx_queue should store it's own copy of name/type values,
+ not the pointer to temporary allocated space.
+
+
+* **pci: Fix memory leaks and needless increment of map address.**
+
+
+* **pci: Fix uio mapping differences between linux and bsd.**
+
+
+* **port: Fix unaligned access to metadata.**
+
+ Fix RTE_MBUF_METADATA macros to allow for unaligned accesses to meta-data
+ fields.
+
+
+* **ring: Fix return of new port id on creation.**
+
+
+* **timer: Fix race condition.**
+
+ Eliminate problematic race condition in ``rte_timer_manage()`` that can lead
+ to corruption of per-lcore pending-lists (implemented as skip-lists).
+
+
+* **vfio: Fix overflow of BAR region offset and size.**
+
+ Fixes: 90a1633b2347 ("eal/Linux: allow to map BARs with MSI-X tables")
+
+
+* **vhost: Fix enqueue/dequeue to handle chained vring descriptors.**
+
+
+* **vhost: Fix race for connection fd.**
+
+
+* **vhost: Fix virtio freeze due to missed interrupt.**
+
+
+* **virtio: Fix crash if CQ is not negotiated.**
+
+ Fix NULL dereference if virtio control queue is not negotiated.
+
+
+* **virtio: Fix ring size negotiation.**
+
+ Negotiate the virtio ring size. The host may allow for very large rings but
+ application may only want a smaller ring. Conversely, if the number of
+ descriptors requested exceeds the virtio host queue size, then just silently
+ use the smaller host size.
+
+ This fixes issues with virtio in non-QEMU environments. For example Google
+ Compute Engine allows up to 16K elements in ring.
+
+
+* **vmxnet3: Fix link state handling.**
Known Issues
------------
-* TODO.
+* When running the ``vmdq`` sample or ``vhost`` sample applications with the
+ Intel(R) XL710 (i40e) NIC, the configuration option
+ ``CONFIG_RTE_MAX_QUEUES_PER_PORT`` should be increased from 256 to 1024.
-API Changes
------------
-
-* TODO.
+* VM power manager may not work on systems with more than 64 cores.
API Changes
-----------
-* TODO.
+* The order that user supplied RX and TX callbacks are called in has been
+ changed to the order that they were added (fifo) in line with end-user
+ expectations. The previous calling order was the reverse of this (lifo) and
+ was counter intuitive for users. The actual API is unchanged.
ABI Changes
-----------
-* TODO.
+* The ``rte_hash`` structure has been changed to internal use only.
