2.2.1.1.11 Performance Counter Frequency

The Performance Counter Frequency attribute specifies how fast the time stamp counters run in ticks per second. This information is particularly useful for deciphering the results from timed probe and probegap tests in the QoS diagnostics type of service. This attribute is optional; implementations SHOULD include it in all Hello frames.
