Subject: [PATCH 0/2] virtio: abstract virtqueue related methods

Hi,

3 weeks ago, I posted a proposal 'Virtio Over Fabrics':
https://lists.oasis-open.org/archives/virtio-comment/202304/msg00442.html

Jason and Stefan pointed out that a non-vring based virtqueue has a
chance to overwrite virtqueue instead of using vring virtqueue.

Then I try to abstract virtqueue related methods in this series, the
details changes see the comment of patch 'virtio: abstract virtqueue related methods'.

Something is still remained:
- __virtqueue_break/__virtqueue_unbreak is supposed to use by internal
  virtio core, I'd like to rename them to vring_virtqueue_break
  /vring_virtqueue_unbreak. Is this reasonable?
- virtqueue_get_desc_addr/virtqueue_get_avail_addr/virtqueue_get_used_addr
  /virtqueue_get_vring is vring specific, I'd like to rename them like
  vring_virtqueue_get_desc_addr. Is this reasonable?
- there are still some functions in virtio_ring.c with prefix *virtqueue*,
  for example 'virtqueue_add_split', just keep it or rename it to
  'vring_virtqueue_add_split'?
