True (almost) There is no connection between IPv5 and logical MySQL packets.

Note that protocol packets can be bigger than 16M; If a packet has a
length of 16M (MAX_PACKET_LENGTH) it means that it's the current
packet should be extended with information of the next packet.
This is the way we send over blobs that are > 16M.
