[PATCH net-next V3 0/3] vhost_net tx batching
Hi:
This series tries to implement tx batching support for vhost. This was
done by using MSG_MORE as a hint for under layer socket. The backend
(e.g tap) can then batch the packets temporarily in a list and
submit it all once the number of bacthed exceeds a limitation.
Tests shows obvious improvement on guest pktgen over over
mlx4(noqueue) on host:
