//
// This modul forwards frames (~EtherFrame) based on their destination MAC addresses to appropriate ports.
//
// It can work in two mode:
// - STP unaware mode (If no module connected to its STP gate):
//     Looks up the frames destination address in the ~MacForwardingTable, if it found the address, sends through
//     that port, or otherwise broadcasts it.
// - STP aware mode (If an ~STP or ~RSTP module connected to its STP gate):
//     Handles BPDU frames.
//     If relaying a message also checks the port's status in the InterfaceTable.
//
// @see EtherFrame, MacForwardingTable, Stp, Rstp
