When VFIO devices are created and if the device is attached to the virtual IOMMU, the ExternalDmaMapping trait implementation is created and associated with the device. The idea is to build a hash map of device IDs with their associated trait implementation. This hash map is provided to the virtual IOMMU device so that it knows how to properly trigger external mappings associated with VFIO devices.
