There's one concern here: are we going to add a
feature flag for flexible layout? If yes this feature
could thinkably just reuse it.
It allows a nice optimization in virtio net that is very easy
with latest qemu.
Rusty, what is our plan wrt this? Are you fine with a per-device
feature bit? Or do we need a transport feature bit (there's the small
issue that we almost run out of them for virtio-pci, do we use the last
one?).
As an aside, the new virtio pci config proposal seems to be stuck too,
are you looking into it or want me to?
