  OVERVIEW:
  
  This software unit holds the implementation of the WLAN BAP modules
  Link Control functions.
  
  The functions externalized by this module are to be called ONLY by other 
  WLAN modules (HDD) that properly register with the BAP Layer initially.

  FUNCTION    WLANBAP_RoamCallback()

  DESCRIPTION 
    Callback for Roam (connection status) Events  

  DEPENDENCIES 
    NA. 

  PARAMETERS 

    IN
      pContext:  is the pContext passed in with the roam request
      pCsrRoamInfo: is a pointer to a tCsrRoamInfo, see definition of eRoamCmdStatus and
      eRoamCmdResult: for detail valid members. It may be NULL
      roamId: is to identify the callback related roam request. 0 means unsolicited
      roamStatus: is a flag indicating the status of the callback
      roamResult: is the result
   
  RETURN VALUE
    The eHalStatus code associated with performing the operation  

    eHAL_STATUS_SUCCESS:  Success

  DESCRIPTION 
    Implements the actual HCI Cancel Logical Link command

  PARAMETERS 

    IN

    pBapHCILogLinkCancel:  pointer to the "HCI Cancel Logical Link" Structure.
   
    IN/OUT
