In rmnet_map_ipv6_dl_csum_trailer() there is an especially involved line of code that determines the ones' complement sum of the IPv6 packet header (in host byte order). Simplify that by storing the result of computing just the header checksum in a local variable, then using that in the original assignment. Use the size of the IPv6 header structure as the number of bytes to checksum, rather than computing the offset to the transport header. And use ip_fast_csum() rather than ipa_compute_csum(), knowing that the size of an IPv6 header (40 bytes) is a multiple of 4 bytes greater than 16. Add some comments to match rmnet_map_ipv4_dl_csum_trailer(). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net> |

README
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.
