  FUNCTION    WLANBAP_STAFetchPktCB 

  DESCRIPTION   
    The fetch packet callback registered with TL. 
    
    It is called by the TL when the scheduling algorithms allows for 
    transmission of another packet to the module. 
    It will be called in the context of the BAL fetch transmit packet 
    function, initiated by the bus lower layer. 


  PARAMETERS

                    and put in the right value for the 
    pucAC:          access category requested by TL, if HDD does not have
