====================
In comment 173ca26e9b51 ("samples/bpf: add comprehensive ipip, ipip6,
ip6ip6 test") we added some bpf tunnel tests. In commit 933a741e3b82
("selftests/bpf: bpf tunnel test.") when we moved it to the current
folder, we missed some points:
1. ip6ip6 test is not added
2. forgot to remove test_ipip.sh in sample folder
3. TCP test code is not removed in test_tunnel_kern.c
In this patch set I add back ip6ip6 test and remove unused code. I'm not sure
if this should be net or net-next, so just set to net.
Here is the test result:
```
Testing IP6IP6 tunnel...

PASS: ip6ip6tnl
```
v3:
Add back ICMP check as Martin suggested.
v2: Keep ip6ip6 section in test_tunnel_kern.c.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
