+/* Theory of operation:
+ *
+ * PTP support is assisted by firmware running on the MC, which provides
+ * the hardware timestamping capabilities.  Both transmitted and received
+ * PTP event packets are queued onto internal queues for subsequent processing;
+ * this is because the MC operations are relatively long and would block
+ * block NAPI/interrupt operation.
+ *
+ * Receive event processing:
+ *	The event contains the packet's UUID and sequence number, together
+ *	with the hardware timestamp.  The PTP receive packet queue is searched
+ *	for this UUID/sequence number and, if found, put on a pending queue.
+ *	Packets not matching are delivered without timestamps (MCDI events will
+ *	always arrive after the actual packet).
+ *	It is important for the operation of the PTP protocol that the ordering
+ *	of packets between the event and general port is maintained.
+ *
+ * Work queue processing:
+ *	If work waiting, synchronise host/hardware time
+ *
+ *	Transmit: send packet through MC, which returns the transmission time
+ *	that is converted to an appropriate timestamp.
+ *
+ *	Receive: the packet's reception time is converted to an appropriate
+ *	timestamp.
