Thanks for pointing us to this solution. We are now building a NAPI version
that makes use of these pseudo-netdev. The fairness amongst other netdevices

We'll change the default behaviour to multi queue, but we'd like to keep
the option to run in a single queue mode for debug and backward compabilty.
