Hi Anders,
ip6erspan is based on ip6gretap, does ip6erspan pass?
it did pass when I was sending the email. However, I retested this on next-20180613 and now it fails.
Does 'ip -s link show' show any errors/dropped on ip6gretap device?
I rerun the test_ip6gretap test only and added "set -x" to test_tunnel.sh here's the output. I added "ip -s link show ip6gretap11" before the cleanup function in the script.

So there are 5 errors at TX.
and today when I tried it on next-20180620 I saw 8 errors at TX.
I couldn't reproduce in my local machine using 4.17-rc6. How do I checkin the "next-20180613" source code?
You can find the source code here [1], and I would look in the latest tag that I said that I was able to reproduce it on above.
