I think you are changing from camel case to snake case.

Is it obvious that CCMPFormatErrors is a part of dot11RSNAStats? OK. You 
added a comment. Often for me the issue is that the comment is only 
valid to one line or to more?

I would prefer something like: dot11rsna_stats_ccmp_format_err
This is keeping the information the author gave variable and I would 
understand better and see it in every place.
