10BASE-T Full Duplex

The 82555 supports 10 Mbps full duplex by disabling the collision function, the squelch test, and
the carrier sense transmit function. This allows the 82555 to transmit and receive simultaneously,
achieving up to 20 Mbps of network bandwidth. The configuration can be achieved through Auto-
Negotiation. Full duplex should only be used in point-to-point connections (no shared media).
Flow control is always disabled.
