    This is not a problem.

    Since the ->enqueue function stores references to the SKBs,
    any change of the dev->qdisc has to flush those references
    somehow, and it is at that point that you can fixup the
    skb queue mappings.

    This happens via invoking the qdisc->ops->reset() method.
