And I rewrote it substantially, mainly to take VIRTIO_RING_F_INDIRECT_DESC into account. As QEMU sets the vq size for PCI to 128, Venkatash's patch wouldn't have made a change. This version does (since QEMU also offers VIRTIO_RING_F_INDIRECT_DESC.That divide-by-2 produced the same queue depth as the prior computation in QEMU was deliberate -- but raising it to 128 seems pretty reasonable.
