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
MFC after: 1 week
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.

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.
not we're going to process the frame; this makes the counters reflect frames
actually processes instead of received (discarded frames were already counted)
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
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
here but it includes completed 802.11g, WPA, 802.11i, 802.1x, WME/WMM,
AP-side power-save, crypto plugin framework, authenticator plugin framework,
and access control plugin frameowrk.
device drivers to declare that the ifp->if_start() method implemented
by the driver requires Giant in order to operate correctly.
Add a 'struct task' to 'struct ifnet' that can be used to execute a
deferred ifp->if_start() in the event that if_start needs to be called
in a Giant-free environment. To do this, introduce if_start(), a
wrapper function for ifp->if_start(). If the interface can run MPSAFE,
it directly dispatches into the interface start routine. If it can't
run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't
currently held, the task is queued to execute in a swi holding Giant
via if_start_deferred().
Modify if_handoff() to use if_start() instead of direct dispatch.
Modify 802.11 to use if_start() instead of direct dispatch.
This is intended to provide increased compatibility for non-MPSAFE
network device drivers in the presence of Giant-free operation via
asynchronous dispatch. However, this commit does not mark any network
interfaces as IFF_NEEDSGIANT.
