  FUNCTION    WLANBAP_XlateRxDataPkt

  DESCRIPTION 

    HDD will call this API when it has received a 802.3 (TL/UMA has 
    Xlated from 802.11) frame from TL and it wants to form a 
    BT HCI Data Packet - ready to signal up to the BT stack application.


  PARAMETERS 

    btampHandle: The BT-AMP PAL handle returned in WLANBAP_GetNewHndl.
    pucAC:       Pointer to return the access category 
    vosDataBuff: The data buffer containing the 802.3 frame to be 
                 translated to BT HCI Data Packet
   
  RETURN VALUE

    The result code associated with performing the operation  

    VOS_STATUS_E_INVAL:  Input parameters are invalid 
    VOS_STATUS_E_FAULT:  BAP handle is NULL  
    VOS_STATUS_SUCCESS:  Everything is good :)

  FUNCTION    WLANBAP_RxProcLsPkt

  DESCRIPTION 

    This API will be called when Link Supervision frames are received at BAP

  PARAMETERS 

    btampHandle: The BT-AMP PAL handle returned in WLANBAP_GetNewHndl.
    pucAC:       Pointer to return the access category 
    vosDataBuff: The data buffer containing the 802.3 frame to be 
                 translated to BT HCI Data Packet
   
  RETURN VALUE

    The result code associated with performing the operation  

    VOS_STATUS_E_INVAL:  Input parameters are invalid 
    VOS_STATUS_E_FAULT:  BAP handle is NULL  
    VOS_STATUS_SUCCESS:  Everything is good :)
