Using ping in tests is error-prone, because ping is too smart. On a flaky system (notably in a simulator), when packets don't come quickly enough, more pings are sent, and that throws off counters. Instead use mausezahn to generate ICMP echo request packets. That allows us to send them in quicker succession as well, because the reason the ping was made slow in the first place was to make the tests work on simulated systems.
