Paolo Abeni deb33b68f4 ip_tunnel: be careful when accessing the inner header
[ Upstream commit ccfec9e5cb]

Cong noted that we need the same checks introduced by commit 76c0ddd8c3

even for ipv4 tunnels.

============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
