Do you mean vring_state_changed() callback? It will not be removed.
BTW, when using vhost pmd, you will not be aware of such callback:
it will be translated to a RTE_ETH_EVENT_QUEUE_STATE interrupt.

OTOH, I have a simple git grep of "vq" from ovs dpdk netdev code,
it returns nothing. So, I don't think that will matter?
