Counts datagrams received by this endpoint whose checksum coverage was strictly smaller than the endpoint's configured minimum coverage threshold, and so violated it. Admins watch this to spot senders that aren't respecting the receiver's minimum coverage requirement, which would indicate a misconfigured or misbehaving remote application. A rising udpliteEndpointViolCoverage count for a media-streaming endpoint would suggest a remote sender is transmitting datagrams with less checksum coverage than this endpoint requires, causing them to be rejected.
