The HLIM feature was miscategorizing probes where the route from the target was shorter than the route to the target. This would result, e.g. in a distance calculation of 9 and a received hop limit of 57. Adding the distance to the hop limit remaining gave a guessed initial hop limit of 66, which would exceed the "64" category. In IPv4 fingerprints, we put the TG test (initial TTL guess) as a range of 5 up or down from the expected number to allow for this and other interference. This patch does the same for IPv6.
Here is some documentation for Nmap, but these files are much less comprehensive than what you'll find at the actual Nmap documentation site ( http://nmap.org ).
