+// The HiiAddPackages() library function requires that any controller (or
+// image) handle, to be associated with the HII packages under installation, be
+// "decorated" with a device path. The tradition seems to be a vendor device
+// path.
+//
+// We'd like to associate our HII packages with the driver's image handle. The
+// first idea is to use the driver image's device path. Unfortunately, loaded
+// images only come with an EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL (not the
+// usual EFI_DEVICE_PATH_PROTOCOL), ie. a different GUID. In addition, even the
+// EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL interface may be NULL, if the image
+// has been loaded from an "unnamed" memory source buffer.
+//
+// Hence let's just stick with the tradition -- use a dedicated vendor device
+// path, with the driver's FILE_GUID.
