While testing our vDPA driver with QEMU we found that vhost_vdpa was
missing some support for PACKED VQs. Adding these helped us get further
in our testing. The first patch makes sure that the vhost_vdpa vqs are
given the feature flags, as done in other vhost variants. The second
and third patches use the feature flags to properly format and pass
set/get_vq requests.
This missed the merge window most likely, unless there's
a reason to send a second pull towards the end of it. We'll see.
Understood - we'll keep our fingers crossed for good luck :-)
Thanks for the help.
