[ Upstream commit31254dc956] When fixing the bpf test_tunnel.sh geneve failure. I only fixed the IPv4 part but forgot the IPv6 issue. Similar with the IPv4 fixes557c223b64("selftests/bpf: No need to drop the packet when there is no geneve opt"), when there is no tunnel option and bpf_skb_get_tunnel_opt() returns error, there is no need to drop the packets and break all geneve rx traffic. Just set opt_class to 0 and keep returning TC_ACT_OK at the end. Fixes:557c223b64("selftests/bpf: No need to drop the packet when there is no geneve opt") Fixes:933a741e3b("selftests/bpf: bpf tunnel test.")

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.
