We used to queue tx packets in sk_receive_queue, this is less
efficient since it requires spinlocks to synchronize between producer

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?

Ignore my message - you are running pktgen from a VM towards the host.
So the numbers you posted are what i was interested in.
Thanks for the good work.

cheers,
