New Features
------------
+* **Added API in ethdev to retrieve RX/TX queue information.**
+
+ * Add the ability for the upper layer to query RX/TX queue information.
+ * Add into rte_eth_dev_info new fields to represent information about
+ RX/TX descriptors min/max/align numbers per queue for the device.
+
+* **Added RSS dynamic configuration to bonding.**
+
+* **Added e1000 Rx interrupt support.**
+
+* **Added igb TSO support for both PF and VF.**
+
+* **RSS enhancement on Intel x550 NIC**
+
+ * Support 512 entries RSS redirection table.
+ * Support per VF RSS redirection table.
+
+* **Flow director enhancement on Intel x550 NIC**
+
+ * Add 2 new flow director modes on x550.
+ * One is MAC VLAN mode, the other is tunnel mode.
+
+* **Added i40e vector RX/TX.**
+
+* **Added i40e flow control support.**
+
+* **Added DCB support to i40e PF driver.**
+
+* **Added fm10k TSO support for both PF and VF.**
+
+* **Added fm10k VMDQ support.**
+
+* **New NIC Boulder Rapid support.**
+
+ Boulder Rapid is a new NIC of Intel's fm10k family.
+
+* **Enhanced support for the Chelsio CXGBE driver.**
+
+ * Added support for Jumbo Frames.
+ * Optimize forwarding performance for Chelsio T5 40GbE cards.
+
+* **Added support for Mellanox ConnectX-4 adapters (mlx5).**
+
+ The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
+ and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
+
+ Like mlx4, this PMD is only available for Linux and is disabled by default
+ due to external dependencies (libibverbs and libmlx5).
+
+* **Added vhost-user multiple queue support.**
+
+* **Added port hotplug support to xenvirt.**
+
Resolved Issues
---------------
+EAL
+~~~
+
+* **eal/linux: Fixed epoll timeout.**
+
+ Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
+ underlying call to ``epoll_wait()`` timed out.
+
+
+Drivers
+~~~~~~~
+
+* **igb: Fixed IEEE1588 frame identification in I210.**
+
+ Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
+ in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
+ Packet Type and not in the default bits 0:2.
+
+* **ixgbe: Fixed issue with X550 DCB.**
+
+ Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
+ with user priority 6 or 7 was injected to the NIC, then the NIC would only
+ put 3 packets into the queue. There was also a similar issue for 4 TCs.
+
+* **ixgbe: Removed burst size restriction of vector RX.**
+
+ Fixed issue where a burst size less than 32 didn't receive anything.
+
+* **i40e: Fixed base driver allocation when not using first numa node.**
+
+ Fixed i40e issue that occurred when a DPDK application didn't initialize
+ ports if memory wasn't available on socket 0.
+
+* **vhost: Fixed Qemu shutdown.**
+
+ Fixed issue with libvirt ``virsh destroy`` not killing the VM.
+
+* **virtio: Fixed crash after changing link state.**
+
+ Fixed io permission in the interrupt handler.
+
+* **virtio: Fixed crash when releasing queue.**
+
+ Fixed issue when releasing null control queue.
+
+
+Libraries
+~~~~~~~~~
+
+* **hash: Fixed memory allocation of Cuckoo Hash key table.**
+
+ Fixed issue where an incorrect Cuckoo Hash key table size could be
+ calculated limiting the size to 4GB.

Known Issues
------------
API Changes
-----------
+* The deprecated flow director API is removed.
+ It was replaced by rte_eth_dev_filter_ctrl().
+
+* The dcb_queue is renamed to dcb_tc in following dcb configuration
+ structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
+ rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
+
+* The function rte_eal_pci_close_one() is removed.
+ It was replaced by rte_eal_pci_detach().
+
+* The deprecated ACL API ipv4vlan is removed.
+
+* The deprecated hash function rte_jhash2() is removed.
+ It was replaced by rte_jhash_32b().
+
+* The deprecated KNI functions are removed:
+ rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
+
+* The deprecated ring PMD functions are removed:
+ rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
+
+* The devargs union field virtual is renamed to virt for C++ compatibility.
+
ABI Changes
-----------
* The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
+* The ethdev flow director entries for SCTP were changed.
+ It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
+
+* The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
+ structure.
+
* The mbuf structure was changed to support unified packet type.
It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
+* The dummy malloc library is removed. The content was moved into EAL in 2.1.
+
+* The LPM structure is changed. The deprecated field mem_location is removed.
+
+* librte_table LPM: A new parameter to hold the table name will be added to
+ the LPM table parameter structure.
+
+* librte_port: Macros to access the packet meta-data stored within the packet
+ buffer has been adjusted to cover the packet mbuf structure.
+
+* librte_cfgfile: Allow longer names and values by increasing the constants
+ CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
