For non-ML stations, the fields are correctly filled from sta->deflink and corresponding sinfo->filled bit are set, but for MLO any one of link's data is filled and corresponding sinfo->filled bit is set. For MLO before embed NL message, fields of sinfo structure like bytes, packets, signal are updated with accumulated, best, least of all links data. But some of fields like rssi, pertid don't make much sense at MLO level. Hence, to prevent misinterpretation, clear sinfo->filled for fields which don't make much sense at MLO level. This will prevent filling misleading values in NL message.
