We have not directly tried to use the 1.7 code with fragmentation apis, but we
did run through the 1.7 code and did not find any much difference between 1.6
and 1.7 code.
I had wrongly mentioned out-of-order in my previous mail. Actually out-of-order
is working fine but we are facing issues with overlapping and duplicate
fragments.
In the 1.7 fragmentation code also in file ip_frag_internals.c , function
ip_frag_process we also see this comment
/*
* errorneous packet: either exceeed max allowed number of fragments,
* or duplicate first/last fragment encountered.
*/
Which indirectly suggest that the handling of duplicate first/last fragment is
taken as error. Same with overlapping fragment we could not find any piece of
code which will be doing it.

Please test the latest version and explain how you see the bug.
