| If present this property assigns a fixed PCI domain number to a PCI |
| Endpoint Controller, otherwise an unstable (across boots) unique number |
| will be assigned. It is required to either not set this property at all |
| or set it for all PCI endpoint controllers in the system, otherwise |
| potentially conflicting domain numbers may be assigned to endpoint |
| controllers. The domain number for each endpoint controller in the system |
| must be unique. |
