     flagged by the compiler. The return value usage should be checked

+* **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)``.
+
+  * The vhost API ``rte_vhost_get_queue_num`` is deprecated, instead,
+    ``rte_vhost_get_vring_num`` should be used.
+
+  * Following macros are removed in ``rte_virtio_net.h``
+
+    * ``VIRTIO_RXQ``
+    * ``VIRTIO_TXQ``
+    * ``VIRTIO_QNUM``
+
+  * Following net specific header files are removed in ``rte_virtio_net.h``
+
+    * ``linux/virtio_net.h``
+    * ``sys/socket.h``
+    * ``linux/if.h``
+    * ``rte_ether.h``
+
+  * The vhost struct ``virtio_net_device_ops`` is renamed to
+    ``vhost_device_ops``
+
+  * The vhost API ``rte_vhost_driver_session_start`` is removed. Instead,
+    ``rte_vhost_driver_start`` should be used, and no need to create a
+    thread to call it.
