Seems to be the right attitude to get this thing done :-)

The card manages its own queues and sends filled buffers in the rx
queue and asks for new ones in the tx queue, the stack just waits for
new packets - that would be the zero-copying driver model.
In our current model, between the stack and the driver we could have
those threads to fill the driver's rx queue, and send out buffers in
the tx queue.
Should work, yes.
Adios...
