Commit 5691484df961 ("net: ip6_gre: Fix headroom request in
ip6erspan_tunnel_xmit()") and commit 01b8d064d58b ("net: ip6_gre:
Request headroom in __gre6_xmit()") fix problems in reserving headroom
in the packets tunneled through ip6gre/tap and ip6erspan netdevices.
These two patches included snippets that reproduced the issues. This
patch elevates the snippets to a full-fledged test case.

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.
