Ok, just to jump back in and add my $0.02, I plan to send a patch to 
the ethtool project to do what was suggested (snapshot to /var, and 
diff stats against that for future reference).  I would just like to 
point out that this will introduce inconsistencies between _every_ 
other source of interface stats (ifconfig/procfs/etc).  I can deal 
with that, it just means one more thing to keep track of when you're 
troubleshooting.

Also, I'd like to point out that the "stepping on other peoples toes" 
argument is a bogus one, since most major network vendors include this 
ability, and it's not exactly a concern now.
