  DESCRIPTION 

    This function is used by HDD to register as a client for data services

    STA it services. 

  DEPENDENCIES 

    TL must have been initialized before this gets called.
     
    Restriction: 
      Main thread will have higher priority that Tx and Rx threads thus 
      guaranteeing that a station will be added before any data can be 
      received for it. (This enables TL to be lock free)

    A station must have been registered before the change state can be

    RESTRICTION: A station is being notified as authenticated before the 
                 keys are installed in HW. This way if a frame is received 
                 before the keys are installed DPU will drop that frame.

                    yet constructed and it lies within TL's responsibility
