+* **Support ethernet device hotplug for primary-secondary model.**
+
+  In primary-secondary process model, ethernet devices are regarded as shared
+  by default, attach or detach a device on any process will broadcast to
+  other processes through mp channel then device information will be
+  synchronzied on all processes. While secondary process can still attach
+  or detach a private device (vdev only) with specific API.
+
+* **Support ethernet device lock.**
+
+  An ethernet device can be directly or conditionally locked. A directly
+  locked device can't be detached, while when try to detach a conditionally
+  locked device a pre-registered callback will be invoked to perform condition
+  check and decide if it can be detached or not.
