I can't tell you when NAPI will be implemented, since I don't know if
anyone is working on it.

You could try playing around with the CQ notification frequency but if
you're going to hack the driver then I think it would be just as easy
to implement NAPI.  Anyway, give it a try and let us know your results.

Thanks,
  Roland
