[PATCH 3/5] vhost-user-blk: add VIRTIO_F_RING_PACKED feature bit

2020-05-22 Thread Stefan Hajnoczi
Vhost devices have a list of feature bits that the device backend is allowed to control. The VIRTIO_F_RING_PACKED feature is a feature that must be negotiated through all the way to the device backend. Add it so the device backend can declare whether or not it supports the packed ring layout. Sign
