Petr Machata af0a51113c selftests: forwarding: Fix packet matching in mirroring selftests 
In commit 6de6e46d27 ("cls_flower: Fix inability to match GRE/IPIP
packets"), cls_flower was fixed to match an outer packet of a tunneled
packet as would be expected, rather than dissecting to the inner packet and
matching on that.

This fix uncovered several issues in packet matching in mirroring
selftests:

- in mirror_gre_bridge_1d_vlan.sh and mirror_gre_vlan_bridge_1q.sh, the
  vlan_ethtype match is copied around as "ip", even as some of the tests
  are running over ip6gretap. This is fixed by using an "ipv6" for
  vlan_ethtype in the ip6gretap tests.

- in mirror_gre_changes.sh, a filter to count GRE packets is set up to
  match TTL of 50. This used to trigger in the offloaded datapath, where
  the envelope TTL was matched, but not in the software datapath, which
  considered TTL of the inner packet. Now that both match consistently, all
  the packets were double-counted. This is fixed by marking the filter as
  skip_hw, leaving only the SW datapath component active.

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.
