I will not have the time today, and probably not tomorrow, to review
this. I want to take some time to get more hands-on with the UDP
checksumming issues reported by Christian in the previous version (in
order to understand what the problem really is),
https://lore.kernel.org/netdev/1813904.kIZFssEuCH@n95hx1g2/
and I will probably only find time for that in the weekend. If anybody
feels like reviewing the series in the meantime, of course feel free to
do so.

One thing that should definitely not be part of this series though is
patch 11/12. Christian, given the conversation we had on your previous
patch:
https://lore.kernel.org/netdev/20201113025311.jpkplhmacjz6lkc5@skbuf/
as well as the documentation patch that was submitted in the meantime:
https://lore.kernel.org/netdev/20201117213826.18235-1-a.fatoum@xxxxxxxxxxxxxx/
obviously you chose to completely disregard that. May we know why?
How are you even making use of the PTP_CLK_REQ_PPS feature?
