Geetha sowjanya bf90cf76e8 octeontx2-pf: Recalculate UDP checksum for ptp 1-step sync packet 
[ Upstream commit edea0c5a99 ]

When checksum offload is disabled in the driver via ethtool,
the PTP 1-step sync packets contain incorrect checksum, since
the stack calculates the checksum before driver updates
PTP timestamp field in the packet. This results in PTP packets
getting dropped at the other end. This patch fixes the issue by
re-calculating the UDP checksum after updating PTP
timestamp field in the driver.

Fixes: 2958d17a89 ("octeontx2-pf: Add support for ptp 1-step mode on CN10K silicon")

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.
