NIC DMA memory regions API allows to establish mapping of DMA addresses used by NIC to host IOVA understood by the host when IOMMU is absent and NIC cannot address entire host IOVA space because of too small DMA mask. The API does not allow to address entire host IOVA space, but allows arbitrary regions of the space really used for the NIC DMA. A DMA region needs to be mapped in order to perform MCDI initialization. Since the NIC has not been probed at that point, its configuration cannot be accessed and there an UNKNOWN mapping type is assumed.
