[Voyage-linux] looking for "wlanconfig <interface> list" command for mac80211 drivers

[Beat Meier]

Hello

I'm trying to use mac80211 drivers and hostapd on voyage-0.7.5.
How can I see the connected stations?
I have nothing found in iw nor in iwlist ...
What I'm searching is the analog command of madwifi
    wlanconfig <interface> list

BTW: New hostapd versions logs a message of the form
RADIUS: starting accounting session 4E1F5481-00000000
What is this?

Thanks

Beat
