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 Jason Wang (8): ptr_ring: introduce batch dequeuing skb_array: introduce batch dequeuing
