Here are 4k sequential read results (cache=none) to check whether we

For the record, here are the commits to selectively mask virtqueues
for ioeventfd and to add -device virtio-net-pci,tx=immediate:
http://repo.or.cz/w/qemu-kvm/stefanha.git/shortlog/refs/heads/virtio-ioeventfd-2
I'm posting this in case you want to try it out too.
