   i40e PMD and its vector PMD enabled by default in powerpc.
 
+* **Added VF max bandwidth setting on i40e.**
+
+  i40e HW supports to set the max bandwidth for a VF. Enable this capability.
+
+* **Added VF TC min bandwidth setting on i40e.**
+
+  i40e HW supports to set the allocated bandwidth for a TC on a VF. Enable this
+  capability.
+
+* **Added VF TC max bandwidth setting on i40e.**
+
+  i40e HW supports to set the max bandwidth for a TC on a VF. Enable this
+  capability.
+
+* **Added TC strict priority mode setting on i40e.**
+
+  There're 2 TX scheduling modes supported for TCs by i40e HW, round ribon mode
+  and strict priority mode. By default it's round robin mode. Enable the
+  capability to change the TX scheduling mode for a TC. It's a global setting
+  on a physical port.
+
+* **Added i40e dynamic device personalization support.**
+
+  * Added dynamic device personalization processing to i40e FW.
+
+* **Added TSO support for tunneled and non-tunneled packets on mlx5 driver.**
+
+  Added support for Hardware TSO for tunneled and non-tunneled packets.
+  Tunneling protocols supported are GRE and VXLAN.
+
+* **Added support for Rx interrupts on mlx5 driver.**
+
+  Rx queues can be armed with an interrupt which will trigger on the
+  next packet arrival.
+
+* **Updated the sfc_efx driver.**
+
+  * Generic flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and TCP
+    pattern items with QUEUE action for ingress traffic.
+
+  * Support virtual functions (VFs)
+
+* **Added LiquidIO network PMD.**
+
+  Added poll mode driver support for Cavium LiquidIO II server adapter VFs.
+
+* **Added support for the Wind River Systems AVP PMD.**
+
+  Added a new networking driver for the AVP device type. Theses devices are
+  specific to the Wind River Systems virtualization platforms.
+
+* **Added vmxnet3 version 3 support.**
+
+  Added support for vmxnet3 version 3 which includes several
+  performance enhancements viz. configurable TX data ring, Receive
+  Data Ring, ability to register memory regions.
+
+* **Updated the tap driver.**
+
+  * Support MTU modification.
+  * Support packet type for Rx.
+  * Support segmented packets on Rx and Tx.
+  * Speed up Rx on tap when no packets are available.
+  * Support capturing traffic from another netdevice.
+  * Dynamically change link status when the underlying interface state changes.
+  * Generic flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and TCP pattern
+    items with DROP, QUEUE and PASSTHRU actions for ingress traffic.
+
+* **Added MTU feature support to Virtio and Vhost.**
+
+  Implemented new Virtio MTU feature into Vhost and Virtio:
+
+  * Add ``rte_vhost_mtu_get()`` API to Vhost library.
+  * Enable Vhost PMD's MTU get feature.
+  * Get max MTU value from host in Virtio PMD
+
+* **Added interrupt mode support for virtio-user.**
+
+  Implemented Rxq interrupt mode support for virtio-user as a virtual
+  device. Supported cases:
+
+  * Rxq interrupt for virtio-user + vhost-user as the backend.
+  * Rxq interrupt for virtio-user + vhost-kernel as the backend.
