This allows increasing the rx queue size up to 1024: unlike with tx, guests don't put in huge S/G lists into RX so the risk of running into the max 1024 limitation due to some off-by-one seems small. It's helpful for users like OVS-DPDK which don't do any buffering on the host - 1K roughly matches 500 entries in tun + 256 in the current rx queue, which seems to work reasonably well. We could probably make do with ~750 entries but virtio spec limits us to powers of two. It might be a good idea to specify an s/g size limit in a future version. It also might be possible to make the queue size smaller down the road, 64 seems like the minimal value which will still work (as guests seem to assume a queue full of 1.5K buffers is enough to process the largest incoming packet, which is ~64K). No one actually asked for this, and with virtio 1 guests can reduce ring size without need for host configuration, so don't bother with this for now.
