ABSTRACT:
Auto-negotiation with a communication partner includes downgrading a set of advertised communications capabilities, e.g., IEEE 802.3 capabilities, when a link with the communication partners fails to support an advertised communications capability, e.g., wire-speed. One operation includes: (1) advertising a first set of communications capabilities; (2) arriving at a first common set of communications capabilities based upon the first set of communications capabilities; (3) attempting to establish a link according to the first common set of communications capabilities; (4) failing to establish a link according to the first common set of communications capabilities; (5) downgrading the first set of communications capabilities to a second set of communications capabilities; (6) advertising the second set of communications capabilities; (6) arriving at a second common set of communications capabilities according to the second common set of communications capabilities; and (7) attempting to establish a link according to the second common set of communications capabilities.
