Hmm, so it's not obvious whether the kvm userspace code handles it
correctly either.

Want to hack something up to use NEXT + INDIRECT, then we can actually test
it?  If it doesn't work, this will have to be a new feature bit.

Also, we have a limitation that you can't have more descriptors than the ring
size, even with indirect, due to overzealous checks...

Thanks,
Rusty.
