Related to hardware revisions (which don't belong here, as David said),
I rather doubt this CVS ID is very useful as a driver version.

If the driver doesn't have a meaningful version (aside from the kernel
version) then you can remove this function and let the ethtool core fill
in the other two fields automatically.
