/** @file
Device Path services. The thing to remember is device paths are built out of
nodes. The device path is terminated by an end node that is length
sizeof(EFI_DEVICE_PATH_PROTOCOL). That would be why there is sizeof(EFI_DEVICE_PATH_PROTOCOL)
all over this file.
The only place where multi-instance device paths are supported is in
environment varibles. Multi-instance device paths should never be placed
on a Handle.
