TAHI IPv6 test failures on 4.19 LTS

[Mahendra SP]

Hi,

We are seeing a total 18 failures when TAHI IPv6 conformance test tool
is run against kernel version 4.19 ( specifically 4.19.29 )

Here are  the tests that are failing:
Section 1
13 tests failed out of 54 tests <test numbers:
16,17,42,43,44,45,46,47,48,49,50,51, 53>

Section 2
1 test failed out of 236 tests <test number 138>

Section 5
4 tests failed out of 25 tests <test numbers 12,17,20,24>

Is anyone else seeing similar kinds of failures ?
Could you please let me know if these are addressed in any of the
latest kernel versions?
If yes, please point me to commits/ fixed versions.

Please let me know if you need any additional information regarding
the above failures.

Thanks
Mahendra
