When a RJ-45 cable connection is made, and each time a LINK is enabled,
auto-negotiation takes place. The LP004A advertises its capability for 10 or 100 Mbps
speed and F/H duplex mode, and the device at the other end of the cable should
similarly advertise / respond and both sides will agree to the speed and mode being
used. Depending upon the device connected, this will result in agreement to operate at
either 10 Mbps or 100Mbps speed, full- or half-duplex mode.
