Edward Cree says: ==================== sfc: fix unaligned access in loopback selftests Arnd reported that the sfc drivers each define a packed loopback_payload structure with an ethernet header followed by an IP header, whereas the kernel definition of iphdr specifies that this is 4-byte aligned, causing a W=1 warning. Fix this in each case by adding two bytes of leading padding to the struct, taking care that these are not sent on the wire. Tested on EF10; build-tested on Siena and Falcon. Changed in v2: * added __aligned(4) to payload struct definitions (Arnd) * fixed dodgy whitespace (checkpatch) ==================== 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.
