A few changes in the "fragmentation & reassembly" area have been happening:

1) Implementation of RFC 5722
2) Implemenation of "improved atomic fragment processing"
3) Improvement of the IPv6 Frag ID generation algorithm

So depending on what you're actually testing, there might be an
interaction among a few of these.

P.S.: I will post some test results asap.
