[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
