What do you mean "thing of the past"?
As far as I know the mac80211 support the BSS management for STA only.
For the AP completely responsible hostapd.
And mac80211 can forward the raw frames in to the hostapd via monitor interface or via netlink socket.
Do you mean that mac80211 in the future will handle AP as well?
Or netlink is more recommended?
Or something other?
