 Yes, and if study it even more carefully, we see that we initialize all tx queues but only a single rx queue (#0).
 After some more code browsing and comparing the two patchsets i figured out that the problem is caused by inappropriate VIRTIO_NET_F_CTRL_VQ flag. In your RFC you used different capability set, while in v1 you seem to have forgotten about this.
 I suggest to temporarily move hw->guest_features assignment out of virtio_negotiate_features() into the caller, where we have eth_dev->dev_type, and can choose the right set depending on it.

 With all mentioned fixes i've got the ping running.
