The matrix keeps every datagram a single UDP fragment (payload < 64 KB): the
UDPSClient reassembly buffer caps a deliverable packet at ~64 KB, so sustained
high-rate streaming must stay below it (see scenarios.py s51). Cases therefore
sweep *count* and *rate*, not oversized single packets.
The matrix keeps every datagram a single UDP fragment for the count/rate axes, but
the *size* axis deliberately crosses the 64 KB single-datagram boundary into the
multi-fragment regime: the UDPSClient reassembles up to UDPS_CLIENT_MAX_PACKET_BYTES
(1 MiB) per packet, so the size sweep runs to ~954 KB packets to exercise that path
under load.
