Forgive me that I'm so insistant on this question, but this is important: What 
state that goes beyond the data settable with wireless ioctls/iwconfig (that 
is kept anyway) needs to be saved by the stack? Last association info is 
worthless, the assocation can be restored using the ESSID/BSSID/channel set 
with iwconfig or by wpa_supplicant. Important is that userspace is notified 
about the connection loss. Is there _any_ other information not recreatable 
from iwconfig settings that needs to be kept?
