LG		 1/** @file\r
2 The device path protocol as defined in UEFI 2.0.\r
3\r
4 The device path represents a programatic path to a device. It's the view\r
5 from a software point of view. It also 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
