Tests test_tunnel.sh fails due to config fragments ins't enabled.

Fixes: 933a741e3b82 ("selftests/bpf: bpf tunnel test.")
Signed-off-by: Anders Roxell <anders.roxell@linaro.org>

---

All tests passes except ip6gretap that still fails. I'm unsure why.
Ideas?

Cheers,
Anders

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.
I couldn't reproduce in my local machine using 4.17-rc6.
How do I checkin the "next-20180613" source code?

Thanks
