Congratulations! Indeed, it looks a lot better:

In fact, I have turned it on on all the remaining failing tests.

In case you want to investigate further, please find the debug output log
at the usual place:

https://domac.alu.unizg.hr/~mtodorov/linux/selftests/net-forwarding/kselftest-6.5-rc3-net-forwarding-18.log.xz

https://domac.alu.unizg.hr/~mtodorov/linux/selftests/net-forwarding/mirror_gre_changes.sh.out.xz

I hope this helps, because you drastically reduced the number of [FAIL] results.

If it matters being heard from me, I think it's a great job!

Kind regards,
