Paul Chaignon d8d2d9d12f selftests/bpf: Test for unaligned flow_dissector ctx access
This patch adds tests for two context fields where unaligned accesses
were not properly rejected.

Note the new macro is similar to the existing narrow_load macro, but we
need a different description and access offset. Combining the two
macros into one is probably doable but I don't think it would help
readability.

vmlinux.h is included in place of bpf.h so we have the definition of
struct bpf_nf_ctx.

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 reStructuredText 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.
