[ Upstream commita625c94144] The MSS calculation in nf_osf_match_one() manually shifts bytes to construct a 16-bit value before passing it to ntohs(). This works on little-endian hosts but it does not work on big-endian as the bytes are being always shifted and set in the same way for all architectures. Use get_unaligned_be16() to fix this on big-endian systems. It also simplifies the code.

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.
