Ah, I think I misunderstood the question and went on elaborating the
same thing, apologies. The other interfaces are not part of the kernel.
They are part of the BlueField Software Package, which also contains
the tools that put together the performance metrics.
My thinking was that since this is a platform driver and is used along
with the BlueField Software Package, consistency with the tools which
were developed following the same convention could be considered,
as long as the driver is not doing something non-standard, of course.
I can change the driver handling to present 64-bit data if you insist.

Thanks,
