TLV 6: Policy Event Serial Number

TLV 6 is used to identify the order in which a policy event occurred.

When the MPE device generates events that send ADS messages to multiple ADS consumers, the serial number can be used by the consumers to reconstruct the original event stream. For example, if there are two active ADS streams and the messages are evenly load balanced across those two streams, stream A will receive messages for events 1, 3, 5, etc. and stream B will receive messages for events 2, 4, 6, etc.
