Seems that Intel has started including a PCIe capability on root
complex integrated endpoints, which can have a smaller size than we're
used to with discrete endpoints and the way capabilities are aligned on
this device results in reporting an erroneous overlap.  I posted a

I don't expect this to be actually causing any problems though.  Thanks,
