+ * @HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as low

+ * @HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
+ *	configuration changes without CLF power off.
+ * @HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example the
+ *	white list).
+ * @HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
