Description (partial)

Symptom:
Not traffic fairness when fair-queue feature is used with tunneled traffic.

Conditions:
When QoS service-policy containing "fair-queue" feature and applied to tunneled traffic, all the traffic would be sent out via a single flow queue.  it's because only the tunnel's outer header information would be seen by "fair-queue" feature, hence considered as the same flow.
