Thanks.  In that case I would prefer the same generic method for all
chip versions, so I'd opt for storing the offset values at rtl_open
time as my patch is doing right now.  Is that acceptable?

If so, wouldn't it make even more sense to use the hardware collected
information in @get_stats64 throughout, except for the numbers collected
*only* in software?  

I would be willing to propose a matching patch.

Thanks,
Corinna
