[ Upstream commit57a92d1465] We have noticed that when PHY timestamping is enabled, L2 frames seems to be modified by changing two 2 bytes with a value of 0. The place were these 2 bytes seems to be random(or I couldn't find a pattern). In most of the cases the userspace can ignore these frames but if for example those 2 bytes are in the correction field there is nothing to do. This seems to happen when configuring the HW for IPv4 even that the flow is not enabled. These 2 bytes correspond to the UDPv4 checksum and once we don't enable clearing the checksum when using L2 frames then the frame doesn't seem to be changed anymore.

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.
