Or when using user space MLME in client mode which is something that I just got working as far as scanning and association is concerned.

That sounds like something that could break multi-BSSID/SSID aware hostapd. Are you saying that there would be new wlanXap like interface for each BSS/VLAN interface? What are the problems this is fixing with multiple AP interfaces? So far, hostapd has been responsible for receiving all management from a single interface and then internally decide which BSS/multi-SSID entry to use for each. I would assume that hostapd could be changed to process frames from multiple interfaces (at least if this is only for multi-BSSID, not for multi-SSID/VLAN case). There may be some special cases, where it would be easier to just be able to use one interface. Likewise, I would expect single interface to be closer to a design that would be using netlink for getting management frames into user space. -- Jouni Malinen PGP id EFC895FA
