I think that you should consider providing a new API as opposed to breaking existing APIs.

And, perhaps this new API could deal with the very rare race to make
it never happen?  No matter how rare it is, you still have to write code
to work around it if it exists..might as well do it once in the kernel
instead of making each user of the interface deal with it.

Personally, I'd like to see the net-device stats (64-bit or otherwise) available
through the ethtool interface in a well defined binary package (perhaps a
struct net_device_stats, or similar.)
