To use this option pass '--zc' parameter:
--zerocopy or --zero-copy maybe better follow what we did with the other parameters :-)
./vsock_perf --zc --sender <cid> --port <port> --bytes <bytes to send>
With this option MSG_ZEROCOPY flag will be passed to the 'send()' call.

I thought we use the current kernel headers when we compile the tests,
do we need to fix something in the makefile?
Not sure, of course we are using uapi. But i see, that defines like SOL_XXX is not
defined in uapi headers. For example SOL_IP is defined in include/linux/socket.h,
but userspace app uses SOL_IP from in.h (at least on my machine). E.g. SOL_XXX is
not exported to user.
Right, I see only few SOL_* in the uapi, e.g. SOL_TIPC in
uapi/linux/tipc.h
So it's fine for now, otherwise we can define it in
uapi/linux/vm_sockets.h
Thanks,
Stefano
