What is mrvEfmOamDupEventNotificationRx?

This read-only counter tracks Event Notification OAMPDUs received whose sequence number matches the last one received, i.e. duplicate/repeated notifications. A high duplicate count relative to unique events can indicate the peer is retransmitting the same fault report because it hasn't seen an ack.
