Few questions about the wireless stack

[Maxim Levitsky <maximlevitsky@gmail.com>]

Hi,

I am trying to understand the relationship between
wireless interfaces (wlan0, mon0,..) and wireless driver.

The most important question I am after, is what types of interfaces I can
run simultaneously? 
(I know that I can run station and monitor, but what are other  combinations ?)

I noticed that in monitor mode iwl3945 appends so called 
'radiotap' header to received packets, but
it seems that mac80211 strips this header, and appends its own,
for monitor interfaces, if so, then why to append it?


And lastly, when you expect AP code to be released?


Best regards,
