You also need to CC Richard.  

We are not talking about PTP, but about specific to RDMA timestamp mechanism
which is added to the CQE (completion queue entry) per-user request when
he/she creates CQ (completion queue). User has an option to choose the format
of it for every QP/RQ/SQ.

I see. Perhaps Richard won't be interested then but best to give him 
a chance.

Not directly related to series at hand but how is the clock synchronized
between system and device for the real time option?
