 New Features
 ------------
 
+* **Extended Statistics**
+
+  Define extended statistics naming scheme to store metadata in the name
+  string name of each statistic, refer to the Extended Statistics section
+  of the programmers guide. Implemented the extended stats API for these
+  PMDs:
+
+  * igb
+  * igbvf
+  * i40e
+  * i40evf
+  * fm10k
+  * virtio
+
+* **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 RSS/FD input set granularity on Intel X710/XL710.**
+
+* **Added fm10k vector RX/TX.**
+
+* **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).
+
+* **Enhanced support for virtio driver.**
+
+  * Virtio ring layout optimization (fixed avail ring)
+  * Vector RX
+  * Simple TX
+
+* **Added vhost-user multiple queue support.**
+
+* **Added port hotplug support to vmxnet3.**
+
+* **Added port hotplug support to xenvirt.**
