Stream identifier with packet counter are used as a nonce. Only 64-bits
of Poly1305 are used.
-It is tuned for 32Kbps bandwidth. 24Kbps should be enough, but 40B of
-IPv6 header, +8B of Poly1305 authentication tag, +4B of stream
-identifier with the counter, +8B of UDP header for 50pps means also
-24Kbps of bandwidth only for overhead transmission.
+It is tuned for 24Kbps bandwidth. But remember that it has additional 8B
