OK, here's a patch that implements the virtio spec update that I sent earlier. It supercedes the PUBLISH_USED_IDX patches I sent out earlier. Support is added in both userspace and vhost-net. I see nice performance improvements: e.g. from 12 to 18 Gbit/s host to guest with netperf, but did not spend a lot of time testing performance. I hope others will try this out and report. Note: there
