Subject: TAHI testing fails for IPv6 Fragments in Kernel 4.9

We are using the TAHI Self-test tools from IPv6 Ready Logo Program:
https://www.ipv6ready.org/?page=documents&tag=ipv6-core-protocols

The test passed up to 4.9.133, then fails ever since.

The are about 20 failing test cases regarding IPv6 fragments,
where the kernel is issuing an ICMPv6 parameter problem pointing
to the Fragmentation Header.

I see lots of commits regarding improving fragment processing.
Has anyone else run TAHI tests on kernel 4.9 or later?
Is there any interest in looking into this to improve
the IPv6 functionality?

Any tips appreciated.
