Specify the list of cores to monitor the ratio of branch misses
to branch hits. A tightly-polling PMD thread has a very low
branch ratio, therefore the core frequency scales down to the
minimum allowed value. On receiving packets, the code path changes,
causing the branch ratio to increase. When the ratio goes above
the ratio threshold, the core frequency scales up to the maximum
