I'm not sure I agree, but that's not the key point.
The key point is that we want the stats to come via a protocol specific
interface, and not have to be fished out of the ethtool -S goop. You
can still collect them in the driver, if we have any ULP-level stats at
any point we can add them to the same interface.
