vdpa: handling of VIRTIO_F_ACCESS_PLATFORM/VIRTIO_F_ORDER_PLATFORM
...e to raise the question of whether we can drop the requirement
of VIRTIO_F_ACCESS_PLATFORM from vdpa?
As far as I can see, it is merely required for virtio vdpa -
so should we not enforce it there?
The point is support for legacy guests - which mostly just works
on x86.
Also, what is the plan for VIRTIO_F_ORDER_PLATFORM?

[PATCH 0/4] virtio-net: don't busy poll for cvq command
Hi all:
The code used to busy poll for cvq command which turns out to have
several side effects:
1) infinite poll for buggy devices
2) bad interaction with scheduler
So this series tries to use sleep + timeout instead of busy polling.
Please review.
Thanks
Changes since RFC:
- switch to use BAD_RING in virtio_break_device()
- check virtqueue_is_broken() after being woken up
- use
