A new year, another month => time to bring this up once more. The latest
revision of the patch series hasn't brought up further requests for
improvement. There still is growing demand for this feature.

David, do you think it is ready to get included?

John acknowledged the changes to clocksource.h. clocksync is independent
of everything else and not active unless called; if driver developers
don't find it useful, it can be replaced/removed. That leaves the API,
which hasn't triggered any comments so far. As proof that it works as
intended I adapted PTPd to use it:

If further discussion of the API is necessary to get this into mainline,
perhaps including the patches in netdev-next would help to encourage
that discussion?

Is there anything I can do myself, like rebasing against the latest
netdev-next?

Bye, Patrick
