The real question is now whether we'd want a separate indirect cache for the 3 case (so num above should be a bitmap?), or reuse the same one, or not use it at all? Benchmarking will tell...
Since there are no specific decisions about actual values, I'll just modify the code to use cache per-vq instead of per-device. Thanks, Sasha
