> This is prepatory work for an expanding list of adapter families that have
> occasional ~10 hour clock jumps when being used for PTP. Factor out the
> sanitization function and convert to using a feature (bug) flag, per
> suggestion from Jesse Brandeburg.
> 
> Littering functional code with device-specific checks is much messier than
> simply checking a flag, and having device-specific init set flags as needed.
> There are probably a number of other cases in the e1000e code that
> could/should be converted similarly.
