# ---------------------------------------------------------------------
- # A code refactoring is required as this type check is present as
- # Interface implement behaviour for one of it's sub-class.
-
- # It is required as the current pattern for vlan is:
- # Interface('name').remove() to delete an interface
- # The code should be modified to have a class method called connect and
- # have Interface.connect('name').remove()
-
- # each subclass should register within Interface the pattern for that
- # interface ie: (ethX, etc.) and use this to create an instance of
- # the right class (EthernetIf, ...)
-
- # Ethernet interfaces can not be removed
-
- # Commented out as nowhere in the code do we call Interface()
- # This would also cause an import loop
- # if self.__class__ == EthernetIf:
