Which device do you suggest using for this test?

You may use software vhost-net backend with and without fix to compare. Since this driver fix effectively lowers down the buffer size for the indirect=on case as well, it's a natural request to make sure no perf degradation is seen on devices with indirect descriptor enabled. I don't expect degradation though and think this patch should improve efficiency with less memory foot print.
