    Yardstick TC071 config file;
    Measure cache hit/miss ratio and usage, network throughput and latency;
    Different amounts of flows are tested with, from 2 up to 1001000;
    All tests are run 2 times each. First 2 times with the least
    amount of ports, then 2 times with the next amount of ports,
    and so on until all packet sizes have been run with;
    During the measurements cache hit/miss ration, cache usage statistics and
    network latency are recorded/measured using cachestat and ping, respectively;
