1. A method for selecting a fast retrain technique in a network connection, the method comprising:
establishing a link between a physical layer device and a link partner by performing link training;
in response to determining that the link has become at least partially inoperative, executing a first fast retrain technique, including executing each retraining step of a first plurality of retraining steps;
receiving a signature indicating that the first fast retrain technique successfully began but failed during execution before completion of the first fast retrain technique;
in response to receiving the signature, and based on the indication that the first fast retrain technique successfully began but failed during execution, executing a second fast retrain technique different from the first fast retrain technique.
