This sub type may not be very useful for normal systems,
but it will be used to support "host" devices on U-Boot sandbox

The UEFI spec 2 has this output example:
Unit(LUN)
In EDK2:
MdePkg/Library/UefiDevicePathLib/DevicePathToText.c:1019:
UefiDevicePathLibCatPrint (Str, L"Unit(0x%x)", LogicalUnit->Lun);
Please, correct the output format to match EDK2 (and the spec).
Best regards
Heinrich
