Currently action frames TX only with ML address as A3(BSSID) are allowed in an ML AP, but TX for a non-ML Station can happen in any link of an ML BSS with link BSS address as A3. In case of an MLD, if User-space has provided a valid link_id in action frame TX request, allow transmission of the frame in that link.
