[PATCH net-next V3 0/6] switch to use tx skb array in tun
Hi all:
This series tries to switch to use skb array in tun. This is used to
eliminate the spinlock contention between producer and consumer. The
conversion was straightforward: just introdce a tx skb array and use
it instead of sk_receive_queue.
A minor issue is to keep the tx_queue_len behaviour, since tun used to
use it for the length of sk_receive_queue. This is done through:
- add the

[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 V2] tun: introduce tx skb ring
We used to queue tx packets in sk_receive_queue, this is less
efficient since it requires spinlocks to synchronize between producer
and consumer.
This patch tries to address this by:
- introduce a new mode which will be only enabled with IFF_TX_ARRAY
set and switch from sk_receive_queue to a fixed size of skb
array with 256 entries in this mode.
- introduce a new proto_ops peek_len which was
