DESCRIPTION

34       Simple interfaces attached to a subsystem. Multiple interfaces can
35       attach to a subsystem and its devices. Unlike drivers, they do not
36       exclusively claim or control devices. Interfaces usually represent a
37       specific functionality of a subsystem/class of devices.
