Yes, and would I suggest limiting the scope of the present series just
to allow changing the global, device-level time stamping layer
administratively.

Trying to support multiple time stamps from different layers is a much
larger development project, and it will require new kernel/user
interfaces.

(Of course it would be grand if the series is forward looking to the
day when time stamp reporting expands beyond the current hw/sw cmsg.)

Thanks,
Richard
