About Auto-negotiation
Auto-negotiation is an IEEE 802.3 procedure of
negotiating the highest data flow capability between
the device (in this case, our Adapter) and their links
partner (some other device). The data flow
information, to be negotiated, consists of the data
speed (10Mbps or 100Mbps) and data transfer
(half-duplex or full-duplex communication). The
physical process of auto-negotiation requires only a
few milliseconds to choose the fastest
communications capability between the two
devices.
