So it's public info that Connect-X has it:

Given the nature of SyncE, I think you can extrapolate from that about

Anyway, Petr and I started discussing this with the colleagues defining
the HW/SW interfaces and we will help with the review to make sure we
end up with a uAPI that works across multiple implementations.
