bfba17efd6 rev 1.19 fixed wpa supplicant but broke wpa authenticator; when operating 
as an authenticator need to always check for the unicast key in the node
(as was the case before)

9b44db51a1 propagate state kept in the bss node when re-creating the node 
on state transitions; this is a stopgap measure, need to rethink
how we do management of this state

a1edfec034 correct check for unicast key being setup; wpa_supplicant in particular 
uses only the global key state so looking in the per-node key slot is wrong

c1c8fdfa03 o replace out-of-line copy of FCS w/ a flag that indicates the 
frame includes FCS (requires applications to be updated, but since
  we weren't doing the out-of-line FCS stuff anyway app changes
  were needed already)
o add a flag to indicate padding exists between the 802.11 header and
  the payload (e.g. for Atheros cards)
o diff reducation against netbsd

ae59d17866 Explicitly ignore ibss merge requests when the node is ic_bss. This can 
happen on the first management frame received from a neighbor; we assume
any merge candidate will send more frames and those should be processed
with a suitable table entry.

c32261430c Simplify the logic for checking the scan candidates at the end of a scan. 
Hold a lock on the table instead of futzing with reference counts which
was potentially dangerous except drivers were quiescent while we did this
so the table contents never changed.  Disable the hack logic for removing
scan candidates with multiple association failures; it's never done the
right thing and will be fixed correctly with background scanning goes in.

07d33c069a move beacon/probe response counting down to after we've decided whether or 
not we're going to process the frame; this makes the counters reflect frames
actually processes instead of received (discarded frames were already counted)

141330c912 fixup inactivity timers: 
o ic_inact_auth is a bad name, it's the inactivity threshold
  for being associated but not authorized; use it that way
o reset ni_inact when switching inactivity thresholds to
  minimize the race against the timer (don't want to lock
  for this stuff)
o change the inactivity probe threshold from a one-shot to
  cover a range: when below this threshold but not expired
  send a probe each inactivity interval; should probably
  guard against the interval being turned way down as this
  could cause us to spam the net with probes

7c448457f6 Relearn how WPA keying is supposed to work and fix WPA+WME while 
we're at it:
o WPA/802.11i has a unicast key and a group key; in station mode
  everything is sent with the unicast key--we were consulting the
  destination mac address and incorrectly using the group key
o (perpetuate fallback use of the default tx key to maintain
  compatibility with the way wpa_supplicant works)
o correct EAPOL encryption logic to check unicast key instead
  of assuming other state implies this
o move QoS encapsulation up to before enmic work so TKIP has the
  information required to calculate the pseudo-header
o do not do QoS-encapsulation of EAPOL frames as some ap's do the
  wrong thing with such frames (may need to revisit this if ap's
  start dropping non-QoS frames from stations assoc'd with QoS)
o move ieee80211_mbuf_adjust closer to its caller
