Let's avoid using VHOST_F_LOG_ALL, using the get_mdev_features()
instead.
Thanks, I will remove VHOST_F_LOG_ALL

Why not having VIRTIO_F_IOMMU_PLATFORM and VIRTIO_F_ORDER_PLATFORM?
I will add VIRTIO_F_ORDER_PLATFORM, for VIRTIO_F_IOMMU_PLATFORM, if we
add this bit, QEMU may enable viommu, can cause troubles in LM
Qemu has mature support of vIOMMU support for VFIO device, it can shadow
IO page tables and setup them through DMA ioctl of vfio containers. Any
issue you saw here?
Btw, to test them quickly, you can implement set_config/get_config and
test them through virtio-mdev/kernel drivers as well.
Thanks
(through we don't support LM in this version driver)
