addresses. In determining this limit, servers only count the size of
successfully processed packets.

Clients MUST ensure that UDP datagrams containing Initial packets are sized to
at least 1200 bytes, adding padding to packets in the datagram as necessary.
Once a client has received an acknowledgment for a Handshake packet it MAY send
smaller datagrams. Sending padded datagrams ensures that the server is not
overly constrained by the amplification restriction.
