If there is a way to expose these stats through vhost_net directly,
instead of through tun, that may be better. But I did not see a
suitable interface. Perhaps debugfs.
Please don't use debugfs, thank you :-)
Okay. I'll take a look at tracing for on-demand measurement.
This reminds me a past series that adding tracepoints to vhost/net[1].
It can count zero/datacopy independently and even contains a sample
program to show the stats.
Thanks
