[Qemu-devel] [PATCH v4 4/9] virtio-blk: move x-data-plane qdev property to virtio-blk.h

[Stefan Hajnoczi <stefanha@redhat.com>]

Move the x-data-plane property.  Originally it was outside since not
every transport may wish to support dataplane.  But that makes little
sense when we have a dedicated CONFIG_VIRTIO_BLK_DATA_PLANE ifdef
already.

This move makes it easier to switch to property aliases in the next
patch.
