Message is used in the LE legacy pairing Transport Specific Key Distribution phase to distribute Encrypted Diversifier (EDIV) and Random Number (Rand) which are used when encrypting future connections.
The message shall only be sent when the link has been encrypted or re-encrypted using the generated LTK.
Legacy: #2 in distribution
Notable: No endian wise conversion shall occur on this data, since the encryption values are interpreted as little-endian or as a byte stream.
