+* **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.
