The LTSSM state machine can enter the polling.compliance substate where the
transmitter is required to transmit a compliance pattern as specified in the PCIe Base
Specification 2.0. The polling.compliance substate is intended to assess if the
transmitter is electrically compliant with the PCIe voltage and timing specifications.
The compliance pattern is a repeating sequence of the following four code groups:
