Suppose you have one multiqueue-capable ethernet card. How can you
connect it to multiple rx/tx queues?
tx is in principle doable, but what about rx?
What does "only map one of these" mean? Connect the device with one
queue (presumably rx), and terminate the others?
Will packet classification work (does the current multiqueue proposal
support it)?
