It appears to be some kind of latency optimisation for busses, but I can;t
really work out what it does. Theres a whitepaper about it here:

The claim is that it can reduce system latency by proritising certain
streams. I think. If you could express these priorities to the kernel it
might be of some use.
Anyone know more about it?
