Suggest VIRTIO_NET_F_HASH_REPORT if specified in device
parameters.
If the VIRTIO_NET_F_HASH_REPORT is set,
the device extends configuration space. If the feature
is negotiated, the packet layout is extended to
accomodate the hash information. In this case deliver
packet's hash value and report type in virtio header
extension.
Use for configuration the same procedure as already
used for RSS. We add two fields in rss_data that
controls what the device does with the calculated hash
if rss_data.enabled is set. If field 'populate' is set
the hash is set in the packet, if field 'redirect' is
set the hash is used to decide the queue to place the
packet to.

Of course, it is similar to the one you wrote inline.
Unlike one you wrote inline this patch does not fail on checkpatch.
But the idea is the same, hard to invent something.
Please just let me know what exactly should I do: resubmit or not and
whether it is possible to fix it without resubmission.

If you feel you modified it significantly enough, you can write
"based on a patch by mst".

Same caveat about attribution to MST.
Once told tha, I don't understand why you are using a unit16_t.
You define indirections_len as:
+ uint16_t indirections_len;
But its maximum value right now is:
+#define VIRTIO_NET_RSS_MAX_TABLE_LEN 128
So, are we planning to increase that value in the next future, or we
just want to give enough space?
Later, Juan.

The max size according to spec is u16. Using that limits
the size and makes it forward compatible.

You need to do something to avoid breaking migration compatibility
from/to old QEMU's and from/to QEMU's on hosts without the new virtio
features.
Probably adding a .needed = here pointing to a function that
checks 'enabled' might do it.

Another question about migration support:
What is expected/required behavior?
Possible cases:
old qemu -> new qemu
new qemu (new feature off) -> old qemu
new qemu (new feature on) -> old qemu

This is the bigger "abuser" that I have ever seen for a post_load
function. Just to add a trace depending on a value O:-)

It is just a similar thing, not the same.
If you add a new field, you need to increase the version number. And
that make backward compatibility really annoying.
With subsections, you can make it work correctly with old versions
always that you don't use rss.
> Another question about migration support:

> Possible cases:

That should always work.
If you use an optional subsection this works for free. Old qemu has no
rss subsection.
> new qemu (new feature off) -> old qemu
This is desirable. And with the optional subsection it just works, no
chang eneeded.
> new qemu (new feature on) -> old qemu
This obviosly will not work, and we are fine. There will appear a new
subsection that old qemu don't undertand. Destination will give one
error and give up.
For one example, just look at something like:
hw/virtio/virtio.c:: vmstate_virtio
There are lots of subscitnsios there.
Later, Juan.

Just works.
Also be careful about the definition of 'new feature off'; normally we
tie these things to machine types, so that with the old machine type the
guest doesn't even see the feature; it can't turn it on.
> new qemu (new feature on) -> old qemu
Fails; hopefully nicely.
