====================
selftests: Add tests for mirroring to gretap

This suite tests GRE-encapsulated mirroring. The general topology that
most of the tests use is as follows, but each test defines details of
the topology based on its needs, and some tests actually use a somewhat
different topology.

The following axes of configuration space are tested:

- ingress and egress mirroring
- mirroring triggered by matchall and flower
- mirroring to ipgretap and ip6gretap
- remote tunnel reachable directly or through a next-hop route
- skip_sw as well as skip_hw configurations

Apart from basic tests with the above mentioned features, the following
tests are included:

- handling of changes to neighbors pertinent to routing decisions in
  mirrored underlay
- handling of configuration changes at the mirrored-to tunnel (endpoint
  addresses, upness)

A suite of mlxsw-specific tests will be part of a separate submission
through linux-mlxsw patch queue.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
