I just notice that the device is a transtitional one. Any reason for doing this?
Note that IFCVF is a moden device anyhow (0x1041). Supporting legacy drive may bring many issues (e.g the definition is non-nomartive). One example is the support of VIRTIO_F_IOMMU_PLATFORM, legacy driver may assume the device can bypass IOMMU.
Thanks
