[PATCH RFC v8 02/11] vhost: use batched get_vq_desc version
...the host:
> - netperf UDP_STREAM shows a performance increase of 1.8, almost
> doubling performance. This gets lower as frame size increase.
> - rests of the test goes noticeably worse: UDP_RR goes from ~6347
> transactions/sec to 5830
> - TCP_STREAM goes from ~10.7 gbps to ~7Gbps
Which direction did you mean here? Guest TX or RX?
> - TCP_RR from 6223.64 transactions/sec to 5739.44
Perf diff might help. I think we can start from the RR result which
should be easier. Maybe you can test it for each patch then you may see
which patch is the source of the regressio...

.../sec to 5830
OK so it seems plausible that we still have a bug where an interrupt
is delayed. That is the main difference between pmd and virtio.
Let's try disabling event index, and see what happens - that's
the trickiest part of interrupts.

[PATCH RFC v8 00/11] vhost: ring format independence
This still causes corruption issues for people so don't try
to use in production please. Posting to expedite debugging.
This adds infrastructure required for supporting
multiple ring formats.
The idea is as follows: we convert descriptors to an
independent format first, and process that converting to
iov later.
Used ring is similar: we fetch into an independent struct first,
convert that to
