The the paeg-per-vq option controlles the VQ Notification Virtio Capability,
added since QEMU 2.8(commit d9997d89a4). It could bring some flexibility[1][2]
to vhost_vdpa.
Gavi, I am not very clear about how it can help with vhost_vdpa. So I
paste some description from the doc of your previous patch[3]. And feel
free to rely with your "Signed-off-by: " :)
