I really don't care what API I end up using..I am just looking for some
way to report to users whether the STA is in the various states that
used to be defined as something similar to:

enum ieee80211_state {
         IEEE80211_UNINITIALIZED = 0,
         IEEE80211_INITIALIZED,
         IEEE80211_ASSOCIATING,
         IEEE80211_ASSOCIATED,
         IEEE80211_AUTHENTICATING,
         IEEE80211_AUTHENTICATED,
         IEEE80211_SHUTDOWN
};

I have been reading the net/wireless code, but so far I don't see
any state machine type logic where this state might be kept.  Maybe
it would have to be inferred from something else?

Thanks,
Ben
