When injecting frames in the Ocelot switch driver an injection header
(IFH) should be used to configure various parameters related to a given
frame, such as the port onto which the frame should be departed or its
vlan id. Other parameters in the switch configuration can led to an
injected frame being sent without an IFH but this led to various issues
as the per-frame parameters are then not used. This is especially true
when using multiple ports for injection.
The IFH was injected with the wrong endianness which led to the switch
not taking it into account as the IFH_INJ_BYPASS bit was then unset.
(The bit tells the switch to use the IFH over its internal
configuration). This patch fixes it.
In addition to the endianness fix, the IFH is also fixed. As it was
(unwillingly) unused, some of its fields were not configured the right
way.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
