1. At the time of the patch there was no dpdk-kmods repo.

2. The patch is for dpdk-draft-windows repo,
   which was using Vistual Studio projects instead of meson.

Yes.
Particularly for virtio it would also be required to support reading PCI
config space in bus/pci/windows (netuio already provides the support).
