[PATCH net-next V2] tun: introduce tx skb ring
...duce a new proto_ops peek_len which was used for peeking the
skb length.
- implement a tun version of peek_len for vhost_net to use and convert
vhost_net to use peek_len if possible.
Pktgen test shows about 18% improvement on guest receiving pps for small
buffers:
Before: ~1220000pps
After : ~1440000pps
The reason why I stick to new mode is because:
- though resize is supported by skb array, in multiqueue mode, it's
not easy to recover from a partial success of queue resizing.
- tx_queue_len is a user visible feature.

So this is more exercising the skb array improvements. For tun
it would be useful to see general performance numbers on user/kernel
crossing (i.e tun read/write).
If you have the cycles can you run such tests?
