-    Creates avocado test suite / config file, and input file needed for yaml files in that config files.
+    1. Creates modified configuration file name according to type of interface from original configuration file

+        inputfile (str): The path to the input file containing configuration data.
+        interface (list): The details of Interface in list format.
+        config_type (str): The type of configuration to generate. Ex: PCI, vNIC etc.
