Stats on large scale setups/systems is problematic and ethtool
is a part of that problem.

Extensibility in general suffers because of the ioctl() interface as
well.

For getting ethtool settings or stats, we have no clean filtering
mechanism.

I could go on and on...

I think before any new features are added to ethtool, we move over to
the netlink based interface and lock the existing ioctl() API in stone.
