To enable radar detection with MLO, it’s essential to handle it on a per-link basis. This is because when using MLO, multiple links may already be active and beaconing. In this scenario, another link should be able to initiate a radar detection. Also, if underlying links are associated with different hardware devices but grouped together for MLO, they could potentially start radar detection simultaneously. Therefore, it makes sense to manage radar detection settings separately for each link by moving them back to a per-link data structure.
