uPadding

snCoded (4 bytes): A 32-bit unsigned value that contains the sequence number for a Coded Packet.

snSourceStart (4 bytes): A 32-bit unsigned value that specifies the first sequence number of a Source Packet that is contained in the FEC payload.

uRange (1 byte): An unsigned 8-bit value that, when added to snSourceStart, yields the last sequence number of a Source Packet that is contained in the FEC payload.

uFecIndex (1 byte): An 8-bit unsigned value. This value is generated by the FEC engine.

uPadding (2 bytes): An array of UINT8 ([MS-DTYP] section 2.2.47).
