Expand description

Virtqueue management wrappers.

This is a slightly opinionated wrapper that presents the underlying Device and Driver rings as a single ‘virtqueue’ where descriptor chains can be retrieved, walked or iterated, and then returned.

The primary opinionated decision taken by this wrapper is that a descriptor chain is considered a formal object that can automatically returns itself to the queue when dropped. This return is then required to have a mechanism to potentially signal the guest driver, via the DriverNotify trait.
