Change Details

Some drivers, e.g. if_enc(4), only allow one instance to be created, but the KPI ifc_attach_cloner() treat zero as not limited, aka IF_MAXUNIT . Introduce a new flag IFC_F_LIMITUNIT to indicate that the provided maxunit is limited and should be respected. Consumers are advised to use the new flag if there is an intended limit. The usage will be easier to grep. The behavior keep unchanged for old KPI if_clone_simple() and if_clone_advanced(). MFC after: 1 week
