It may be fine as a requirement of the day but it does not bode well
for the future as ethtool stats API won't get less messy.

I'd rather see ethtool stats provides one of those:
1. hardware stats only
2. driver dependent stats - anything you want - as long as the hardware
   only part of the stats is clearly identified

2. needs works. 1. hurts any requirement where it would priviously had
been so easy to add a few lines of code in the driver and push the mess
straight from kernel to the end user application.
