//     Top module of MAC Layer Ethernet Switch.                               //

//     The system has 6 ports , each one connected                            //

//     to Network Adapter (in hosts).                                         //

//     The system can  receive and transmit packets                           //

//     Simultaneously in full wire speed (100 MB/s).                          //

//                                                                            //
