Alex Elder says: ==================== net: ipa: abstract status parsing Under some circumstances, IPA generates a "packet status" structure that describes information about a packet. This is used, for example, when offload hardware detects an error in a packet, or otherwise discovers a packet needs special handling. In this case, the status is delivered (along with the packet it describes) to a "default" endpoint so that it can be handled by the AP. Until now, the structure of this status information hasn't changed. However, to support more than 32 endpoints, this structure required some changes, such that some fields are rearranged in ways that are tricky to represent using C code. This series updates code related to the IPA status structure. The first patch uses a local variable to avoid recomputing a packet length more than once. The second stops using sizeof() to determine the size of an IPA packet status structure. Patches 3-5 extend the definitions for values held in packet status fields. Patch 6 does a little general cleanup to make patch 7 simpler. Patch 7 stops using a C structure to represent packet status; instead, a new function fetches values "by name" from a buffer containing such a structure. The last patch updates this function so it also supports IPA v5.0+. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
