Symptom:
"Invalid DAVIC message type" alarms are raised when DAVIC message traffic is received that can't be properly validated.  This includes instances where a valid DAVIC message type is found but no MAC address, so the associated packet is discarded as a "broadcast" DAVIC message.  The ability was added to capture the contents of invalid DAVIC messages, and messages being flagged as a broadcast message, and write them to the logs to allow post-analysis/decoding of the data in the ATM cells comprising the message.  Additionally, the VPI/VCI, MAC address and demod associated with the STB that sent the message is captured and logged.

Conditions:
When the D9485 receives a Davic message that is not formatted correctly or missing the mac address
