i did not say it because it will work without any extra effort:
- the netmap version i committed a few days ago already fetch
  the number of queues and the ring sizes at runtime;
- ethtool (or whatever we will call it) only operates on the
  configuration/control plane (number of queues and slots,
  partitioning of packets onto input queues, etc.), whereas netmap
  operates only on the data plane
