	Support in-order requests for packed rings. This allows selective write-out of used descriptors. Signed-off-by: Michael S.

2018-03-20	packed virtqueues: more efficient virtqueue layout	Michael S. Tsirkin
	Performance analysis of this is in my kvm forum 2016 presentation. The idea is to have a r/w descriptor in a ring structure, replacing the used and available ring, index and descriptor buffer. This is also easier for devices to implement than the 1.0 layout. Several more enhancements will be necessary to actually make this efficient for devices to use. Signed-off-by: Michael S.
