LACP upgrade - 9: updating LACP PDU transmit handler

Updated the #PDU #transmit #handler in the #LACP module. Whenever updated LACP packets has to be sent to the #peer #partner node, the PDUs are #composed from the internal data-structures in this routine. This routine access the member port data-structures for #creating the individual #TLVs in the LACP PDU. The data-structure references has been corrected to the native member port structures. This routine passes the created PDUs to the appropriate #platform #handlers to send them out of the actual port.
