+#### Pod Annotation Parameters

+- namespace: Kubernetes namespace that the target network attach definition is defined in.
+- mac: MAC address (e.g "c2:11:22:33:44:66") for target network interface
+- interfaceRequest: interface name for target network interface
+
+Note: If you add `mac`, please add 'tuning' plugin into target network attach definition as CNI plugin chaining as following.
