+When adding device to white list the device is added to resolving list
+also it has to be added only when HCI_ENABLE_LL_PRIVACY flag is set.
+HCI_ENABLE_LL_PRIVACY flag has to be tested before adding/deleting devices
+to resolving list. use_ll_privacy macro is used only to check if controller
+supports LL_Privacy.
