Where do we stand on this series? People talked about what the core
might be able to do, or how the driver might be able to do things a
little differently, but I didn't hear a clear conclusion on whether or
not to take this series as is (it seems to be a sensible cleanup and
possibly worthwhile even if we end up changing the hfi1 driver to do a
firmware updated followed by a device reset to get the same results).
And more importantly as far as I'm concerned, is this sitting on my
plate or on the PCI people's plate?
