[RFC PATCH 0/2] virtio: allow per vq DMA domain
We used to have use a single parent for all DMA operations. This tends to complicate the mdev based hardware virtio datapath offloading which may not implement the control path over datapath like ctrl vq in the case of virtio-net. So this series tries to intorduce per DMA domain by allowing trasnport to specify the parent device for each virtqueue. Then for the case of virtio-mdev device, it can
