passt/test/perf/passt_udp
Stefano Brivio c3f8e4d2cd test/perf: Actually load passt enough to test UDP performance 
With recent improvements, we're not CPU-bound at all while testing
UDP performance. Give the VM more memory and CPUs, forward two
additional ports, start up to four threads in parallel, and give
single iperf3 threads higher bandwidth targets.
