   * Generic flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and TCP pattern

+* **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 and LSC 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.
+  * LSC interrupt for virtio-user + vhost-user as the backend.

+* **Reworked rte_vhost library**
+
+  The rte_vhost library has been reworked to make it generic enough so that
+  user could build other vhost-user drivers on top of it. To achieve that,
+  following changes have been made:
+
+  * The following vhost-pmd APIs are removed:
+
+    * ``rte_eth_vhost_feature_disable``
+    * ``rte_eth_vhost_feature_enable``
+    * ``rte_eth_vhost_feature_get``
+
+  * The vhost API ``rte_vhost_driver_callback_register(ops)`` is reworked to
+    be per vhost-user socket file. Thus, it takes one more argument:
+    ``rte_vhost_driver_callback_register(path, ops)``.
