Not just for pre-11be clients. 11be clients can opt-out right?

represented by NL80211_IFTYPE_AP associated with a separate netdev.

Two link AP MLD representation:

                  AP MLD
              (netdev + wdev)
                 /      \
                /        \
           wlan0          wlan1
       IFTYPE_AP       IFTYPE_AP
    (netdev + wdev)  (netdev + wdev)
            |             |
            |             |
         radio(2G)      radio(5G)

So the AP MLD is a new IFTYPE? Earlier discussions were suggesting the 
AP MLO links would be bridged, but then there would be only a netdev at 
AP MLD level, right?
