I don't think we have to track used_wrap_counter in
driver. There was a discussion on this:
https://lists.oasis-open.org/archives/virtio-dev/201802/msg00177.html
And after that, below sentence was added (it's also
in the above words you quoted):
"""
Other techniques to detect
VIRTQ_DESC_F_AVAIL/VIRTQ_DESC_F_USED bit changes
might also be possible.

[RFC v2] virtio: support packed ring
Hello everyone,
This RFC implements packed ring support for virtio driver.
The code was tested with DPDK vhost (testpmd/vhost-PMD) implemented
by Jens at http://dpdk.org/ml/archives/dev/2018-January/089417.html
Minor changes are needed for the vhost code, e.g. to kick the guest.
TODO:
- Refinements and bug fixes;
- Split into small patches;
- Test indirect descriptor support;
- Test/fix event
