virtio 1.1 features question

[Don Wallwork <don.wallwork@broadcom.com>]

Is there an expectation that feature names in the spec would match 
implementation in code?
I presume not, since features like VIRTIO_F_EVENT_IDX and 
VIRTIO_F_INDIRECT_DESC do not
appear in Linux kernel or QEMU code; VIRTIO_RING_F_EVENT_IDX and 
VIRTIO_RING_F_INDIRECT_DESC
are used instead.

Also noticed that there seems to be an inconsistency in the spec in that 
VIRTIO_F_EVENT_IDX is
used in some places and VIRTIO_F_RING_EVENT_IDX is used in others.. Is 
this intended?

Thanks,

Don
