Claim One:
1. An apparatus comprising: protocol layer logic, link layer logic, and physical layer logic; the physical layer logic comprising a drift buffer, a transmitter, and a receiver, wherein the physical layer logic is to support differential signaling, wherein the drift buffer is to transfer received bit streams to a local clock domain; the physical layer logic to enter a polling state from another state defined in a state machine, wherein the polling state is one of a plurality of states defined in the state machine for initialization of a link, and the physical layer logic, when in the polling state, is to adapt the receiver, initialize the drift buffer, identify a symbol boundary, lock on a training sequence sent during the polling state based on a header of the training sequence to identify boundaries between a series of training sequences sent in a pattern corresponding to the polling state, initiate deskew of the plurality of lanes, and exit the polling state in response to an acknowledgement.
