I changed link fec through the API and it did not take place in dendrite. Only when I deleted the link and let the RPW recreate it did the fec mode get changed

Research direction

The report names the API, dendrite, and the RPW recreation path but no files or tests. Start by reproducing an API FEC change and compare it with deleting and recreating the link. Trace where the setting is applied, then add coverage showing that the API change updates link FEC without deletion.
