4.2.1.1 Duplex Mode
Ports have the duplex modes: 10M HD, 10M FD, 100M HD, 100M FD and
1000M FD (Giga port support).
The First part indicates the transmission rate and the second part indicates the
duplex mode.
HD: half-duplex, the port supports transmission between the device and
the client in only one direction at a time.
FD: full-duplex, the port supports transmission between the device and its
link partner in both directions simultaneously.
Switch support auto negotiation is a protocol between two link partners that
enables a port to advertise its transmission rate and duplex mode to its
partner.
4.2.1.2 Flow Control
Flow control enables lower speed devices to communicate with higher speed
devices. This is implemented by the higher speed device refraining from
sending packets.
