Unexpected IRT related diagnosis reported

If the IO Device has an active AR which uses IRT and now this AR is simply modified to usw RT instead of IRT after the RT AR is estabished the IO Device will report the following unexpected diagnosis to IO Controller:

• InterfaceSubmodule: Sync mismatch, no Sync message received
• PortSubmodule: Remote mismatch, Peer RT_Class_3 mismatch

20 seconds after establishment of the RT AR the diagnosis is sometimes reported as "disappeared" and everything is fine. Sometimes the diagnosis stays forever.

It is expected that after RT AR is fully established no IRT-related diagnosis is reported.
