Merge branch 'TX-used-ring-batched-updating-for-vhost'
Jason Wang says: ==================== TX used ring batched updating for vhost This series implement batch updating of used ring for TX. This help to reduce the cache contention on used ring. The idea is first split datacopy path from zerocopy, and do only batching for datacopy. This is because zercopy had already supported its own batching. TX PPS was increased 25.8% and Netperf TCP does not show obvious differences. The split of datapath will also be helpful for future implementation like in order completion. ==================== Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S.
