In __nat25_add_pppoe_tag(), the tag length is read from the tag data
structure. The value is kept in network format, but read as raw value.
With -Warray-bounds, this results in the following gcc error/warning
when building the driver on alpha.
In function '__nat25_add_pppoe_tag',
inlined from 'nat25_db_handle' at
drivers/staging/r8188eu/core/rtw_br_ext.c:479:11:
arch/alpha/include/asm/string.h:22:16: error:
'__builtin_memcpy' forming offset [40, 2051] is out of the bounds
[0, 40] of object 'tag_buf' with type 'unsigned char[40]'
Add the missing be16_to_cpu() to fix the compile error. It should be
noted, however, that this fix means that the code did probably not work
on any little endian systems and/or that the driver has other endiannes
related issues. A build with C=1 suggests that this is indeed the case.
This patch does not attempt to fix any of those other issues.

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.
