+
+  This function is always non-blocking. When setting some type of configuration data,
+  an asynchronous process is invoked to check the correctness of the data, such as
+  doing Duplicate Address Detection on the manually set local IPv6 addresses.
+  EFI_NOT_READY is returned immediately to indicate that such an asynchronous process
+  is invoked and the process is not finished yet. The caller willing to get the result
+  of the asynchronous process is required to call RegisterDataNotify() to register an
+  event on the specified configuration data. Once the event is signaled, the caller
+  can call GetData() to get back the configuration data in order to know the result.
+  For other types of configuration data that do not require an asynchronous configuration
+  process, the result of the operation is immediately returned.
