2 The device path protocol as defined in UEFI 2.0.\r
3\r
4 The device path represents a programmatic path to a device,\r
5 from a software point of view. The path must persist from boot to boot, so\r
6 it can not contain things like PCI bus numbers that change from boot to boot.\r

49 This protocol can be used on any device handle to obtain generic path/location\r
50 information concerning the physical device or logical device. If the handle does\r
51 not logically map to a physical device, the handle may not necessarily support\r
52 the device path protocol. The device path describes the location of the device\r
53 the handle is for. The size of the Device Path can be determined from the structures\r
54 that make up the Device Path.\r
