NotethattheReference ID matchestheptp refidfromthechrony.conffileandthatthesourcesoutput
shows the ptp reference id as selected (signified by the * state in the second column). Additionally,
theNTP timesources showa smallrelativeerrorto thehigh accuracyPTP timesource.
Inthis casethe PTPgrandmasteris properlyfunctioning.
Ifthis erroris large,chronywill selecttheNTP timesourcesand markthePTP timesource asinvalid.
This typically signifies that something is mis-configured with the PTP grandmaster upstreamof this
