Just "vRID of Intel VT-d"? the current description is not very clear to me.

Looks like we use "vRID of Intel VT-d to a Context Table" in the Documentation/userspace-api/iommufd.rst, but forgot to change in the uAPI header: * @virt_id: Virtual device ID per vIOMMU, e.g. vSID of ARM SMMUv3, vDeviceID * of AMD IOMMU, and vRID of a nested Intel VT-d to a Context Table

Let me correct both of them.

Thanks Nicolin
