Enhanced switch port 0 can support CC (indicated in CC 
ClassPortInfo:CapabilityMask.EnhancedPort0CC).

portnum 0 is a valid port number and offsets should be calculated based on port 0
rather than port 1.

Also, fix some error messages to indicate switch port congestion setting
rather then switch congestion setting failure.
