1. A method of operating an Ethernet transceiver disposed at one end of a link, the link located proximate to neighboring links, the method comprising:
transmitting first data at a first transmit power level and first data rate to a link partner during a data transfer interval;
detecting feedback during the data transfer interval, the feedback being indicative of crosstalk between the link and one or more of the neighboring links due to the transmitting;
adjusting the first data rate and/or first transmit power level to an adjusted second data rate and/or second transmit power level based on the feedback; and
transmitting second data utilizing the adjusted second data rate and/or transmit power level.
