Currently there is no limit to the number of VFs netdevsim can enable. In a real systems this value exist and used by the driver. Fore example, some features might need to consider this value when allocating memory. Expose max_vfs variable to debugfs as configurable resource. If are VFs configured (num_vfs != 0) then changing of max_vfs not allowed.
