PTP-optimization code upstreamed

[Marta Plantykow]

Hi,
Together with Maciej Machnikowski <maciej.machikowski@intel.com>
<maciejm@nvidia.com> and Milena Olech <milena.olech@intel.com> we would
like to inform you, that the source code of the script used to prepare the
Netdev 0x15 presentation called “Precision Time Protocol optimization
using genetic algorithm” [0] was recently open sourced. The developed
framework provides an easy-to-use automated methodology of tuning the
Proportional-Integral controller embedded in the linuxptp project. In our
research we’ve reached up to 32% smaller mean squared error returned by
phc2sys test (comparing to default PI controller settings).

The code is available under this link [1] along with a short
documentation. A NIC and a driver that supports 1588 is required to run
this test efficiently. All contributions will be considered for acceptance
through pull requests. Do not hesitate to contact us in case of any
questions or concerns.

The process for contributing to upstream kernel is very well documented.
Links to github is useful, but does not start the upstream process.

https://www.kernel.org/doc/html/latest/process/submitting-patches.html#submittingpatches

When can we expect patch set to show up on this mailing list?

Hi Stephen,

This code is not intended to be upstreamed, since it is a set of python scripts
optimizing phc2sys and ptp4l servo.
It reached the netdev mail list because it was presented on the NetDev 
conference, and some people were interested in them during the presentation.

Have a great day!
Maciek

Sure thanks. It still might be good to have this in tools directory.
Or somewhere related to kernel.
