1. An apparatus comprising:
- a layered stack comprising physical layer logic, link layer logic, and protocol layer logic, wherein the physical layer logic is to adapt a serial data link, wherein adaptation of the link is to include;
receiving a pseudorandom binary sequence (PRBS) from a remote agent;
analyzing the PRBS to identify characteristics of the data link; and
generating metric data describing the characteristics.

Abstract
A serial data link is to be adapted during initialization of the link. Adaptation of the link is to include receiving a pseudorandom binary sequence (PRBS) from a remote agent, analyzing the PRBS to identify characteristics of the data link, and generating metric data describing the characteristics.
