  Since the ConnectX-6DX the send scheduling capability is provided.
An application can register the dynamic field and dynamic flags
in mbuf for timestamp and specify the desired moment of time
the packet should sent.

The send scheduling feature over ConnectX-6DX uses the complicated
infrastructure with reference Clock Queue and inter-queue synchronizing
operations. Since ConnectX-7 the new wait descriptor format is
introduced where the timestamp can be promoted to hardware directly.
The patchset adds support for this new hardware option in PMD.
