> Add functions to request Tx timestamp for the PTP packets, read the Tx

>
> Tx timestamp is requested for the PTP packets by setting a TSYN bit and index
> value in the Tx context descriptor. The driver assumption is that the Tx
> timestamp value is ready to be read when the completion tag is received. Then
> the driver schedules delayed work and the Tx timestamp value read is
> requested through virtchnl message. At the end, the Tx timestamp value is
> extended to 64-bit and provided back to the skb.
