This modules handles two types of isochronous packet; one has CIP header in IEC 61883-1/6 and another doesn't. The module also have tracing events corresponding to the types of packet. To unify the events, one event should be probed with or without CIP header.
This commit uses dynamic array for the events to be available for the types of packet.
