[PATCH net-next 0/8] vhost-net rx batching
Hi all:
This series tries to implement rx batching for vhost-net. This is done
by batching the dequeuing from skb_array which was exported by
underlayer socket and pass the sbk back through msg_control to finish
userspace copying.
Tests shows at most 19% improvment on rx pps.
Please review.
Thanks

[PATCH net-next 0/9] TX used ring batched updating for vhost
Hi:
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
