It's not even enabled in our stock kernel. Stats and debug options usually slow down the system or produce some memory overhead. So it's nothing for a
distribution kernel expect in some rare cases.

"Help text

This statistics is not a SNMP/MIB specification but shows statistics about transformation error (or almost error) factor at packet processing for developer.

If unsure, say N."

So use abs and to a custom rebuild.
