 +**Cause:** QPLL can't find a configuration for desired lane rate with the given reference clock.
 +
 +**Identify:** Check boot log. Check the required lane rate ref clock combination against the constraints defined in the transceiver manual.
 +
 +**Fix:** Configure the clock chip for different reference clock or switch to CPLL or QPLL0/1.
