This read-write TruthValue specifies whether bit errors should be deliberately injected into this BERT config stream, per its description. An administrator enables this to intentionally introduce errors and validate that downstream error-detection and reporting mechanisms actually catch them, rather than only ever testing a clean signal. For example, an operator validating that alarm thresholds correctly trigger might set bertConfigStreamErrInjectEnabled to true and pair it with a specific bertConfigStreamErrInjectRate.
