2 The device path protocol as defined in UEFI 2.0.
4 The device path represents a programatic path to a device. It's the view
5 from a software point of view. It also must persist from boot to boot, so
6 it can not contain things like PCI bus numbers that change from boot to boot.

44 This protocol can be used on any device handle to obtain generic path/location
45 information concerning the physical device or logical device. If the handle does
46 not logically map to a physical device, the handle may not necessarily support
47 the device path protocol. The device path describes the location of the device
48 the handle is for. The size of the Device Path can be determined from the structures
49 that make up the Device Path.
