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