So, presumably:

        the payload of a Downstream SC-QAM DOCSIS MAC Frame, OFDM DOCSIS MAC Frame, or Upstream DOCSIS MAC Frame packet 
type is a MAC Frame as described by section 6.2 "MAC Frame Formats" of the DOCSIS 3.1 MAC and Upper Layer Protocols 
Interface Specification (or previous DOCSIS MAC frame specifications);

        the payload of an OFDM NCP packet type is an NCP message block as described by section 8.3.4 "Next Codeword 
Pointer" of the DOCSIS 3.1 Physical Layer Specification (either a data message block or a CRC block);

        the payload of an OFDM PLC packet type is a MAC management message.

What are the payloads of A-TDMA Burst, OFDMA Data Burst, OFDMA Initial Ranging, OFDMA Fine Ranging, and OFDMA Probing 
Sequence packet types, if any?

For all of the fields that don't have obviously numeric values, what are the values those fields can take?

What is the format of the subtyped TLVs' values?  Is there one byte of subtype, followed by the rest of the value?  
What format does the value have for the various subtypes of the various fields?

Is Truncated due to Uncorrectables a 1-byte Boolean, with 0 meaning false and some other value or values (anything 
non-zero?) meaning true?
