  FUNCTION    WLANTL_GetFrames

  DESCRIPTION

    BAL calls this function at the request of the lower bus interface.
    When this request is being received TL will retrieve packets from HDD
    in accordance with the priority rules and the count supplied by BAL.

  DEPENDENCIES

    HDD must have registered with TL at least one STA before this function
    can be called.

  PARAMETERS

    IN
    pAdapter:       pointer to the global adapter context; a handle to TL's
                    or BAL's control block can be extracted from its context
    uSize:          maximum size accepted by the lower layer
    uFlowMask       TX flow control mask. Each bit is defined as 
                    WDA_TXFlowEnumType

  RETURN VALUE

    The result code associated with performing the operation

    1 or more: number of required resources if there are still frames to fetch
               For Volans, it's BD/PDU numbers. For Prima, it's free DXE descriptors.
