This framing is also going to be used with TLS, so you do need
the length there. I'd rather have a consistent framing than
save 3 bytes.
My thought section 5.2.2 is for unreliable link (UDP/DTLS) only. I assume the TLS record layer is sufficient for TCP. Even if framing is used for TCP, wouldn't it be using rfc4571 as suggested by draft-ietf-mmusic-ice-tcp-07? Please clarify.
Please ignore suggestion 2. I misread the Linux man page for udp(7).
