示例1: checkPerSourceMacRate
/**
* Check if we have sampled this mac in the last second.
* Since we check every packetInRatePerMacThreshold packets,
* the presence of the mac in the macCache means the rate is
* above the threshold in a statistical sense.
*
* Take care not to block topology probing packets. Also don't
* push blocking flow mod if we have already done so within the
* last 5 seconds.
