BTW pls see virtio spec in :

"If VIRTIO_NET_F_MQ is negotiated, each of receiveq1. . .receiveqN that will be 
used SHOULD be populated
with receive buffers."

It is not mandatory that all queues must be initialized.

I think not, since it said we should fill receive buffers for each queue which means we should initialize all queues. May Michael can clarify on this.
