'somewhat' is accurate....because it works surprisingly well except for
some niggling bugs.

Yes...these nodes stop sending beacons after "deauth"ing.
It's great that its high on your list.

Nevertheless, would you know of any place where I could lay my hands on
the state transition diagrams for the 802.11 protocol? It would be nice
for the rest of the developer community to have this to work with when
using an experimental driver. Might even help in more accurate analysis
of the bug reports.

The 802.11 draft is OK, but a major pain to go through every time you
need a quick verification about a certain phenomena.
