mac80211 vs. hostapd

[Joerg Pommnitz <pommnitz@yahoo.com>]

Hello all,
can somebody explain the relationship between hostapd and mac80211? To =
be more specific:

I'm used to the Madwifi driver where one could create a virtual interfa=
ce in AP mode and the net80211
stack included in Madwifi would then provide the AP functionality.
I understand that things are differently with mac80211 based drivers. T=
he kernel part of the stack does
not include the AP functionality at all. Handling of associated station=
s is done by hostapd. Is this
correct so far? Does "iwconfig wlan0 mode master" have any meaning? How=
 does one create multiple
virtual interfaces (the equivalent of Madwifis wlanconfig command)?

If so, I could not find a sample configuration for hostapd that provide=
s a simple, unsecured AP.
I suspect that this is because traditionally hostapd has only been used=
 to provide a WPA secured AP.

Is this the right list to ask for such a sample configuration?
