Indeed, would be nice to see what you come up with. I think there may be
value in sending one huge chunk packet which itself is actually a
collection of several independet packets when you have a huge amount of
small packets. The benefit being you amortize the cost of DMA setup.
But then you may need to be able to break them down in the driver; is
this what you are talking about?
