Somehow this snuck into my earlier patch, and
only now did I see a compiler warning:

The key documentation is slightly out of date, fix
that. Also, the list entry in the key struct is no
longer used that way, so list_del_init() isn't
necessary any more there.
Finally, ieee80211_key_link() is no longer invoked
under RCU read lock, but rather with an appropriate
station lock held.

This patch addresses the issue of serialization between
the main rx path and various reorder release timers.
<http://www.spinics.net/lists/linux-wireless/msg57214.html>
It converts the previously local "frames" queue into
a global rx queue [rx_skb_queue]. This way, everyone
(be it the main rx-path or some reorder release timeout)
can add frames to it.
Only one active rx handler worker [ieee80211_rx_handlers]
is needed. All other threads which have lost the race of
"runnning_rx_handler" can now simply "return", knowing that
the thread who had the "edge" will also take care of their
workload.

Fixed a bug where if a mesh interface has a different MAC address from its bridge
interface, then it would not be able to send data traffic to any other mesh node.
This also adds support for communication between mesh nodes and external bridged
nodes by using a 6 address format if the source is a node within the mesh and the
destination is an external node proxied by a mesh portal.

This patch tackles one of the problems of my
reorder release timer patch from August.
<http://www.spinics.net/lists/linux-wireless/msg57214.html>
=>
What if the reorder release triggers and ap_sta_ps_end
(called by ieee80211_rx_h_sta_process) accidentally clears
the WLAN_STA_PS_STA flag, because 100ms ago - when the STA
was still active - frames were put into the reorder buffer.

mac80211: simplify key locking
removed the synchronization against RCU and thus
opened a race window where we can use a key for

iwlwifi and other drivers like to blink their LED
based on throughput. Implement this generically in
mac80211, based on a throughput table the driver
specifies. That way, drivers can set the blink
frequencies depending on their desired behaviour
and max throughput.
All the drivers need to do is provide an LED class
device, best with blink hardware offload.

The throughput trigger will require doing LED
classdev/trigger handling before register_hw(),
so drivers should have access to the trigger
names before it. If trigger registration fails,
this will still make the trigger name available,
but that's not a big problem since the default
trigger will the simply not be found.

When an skb is shared, it needs to be duplicated, along with its data buffer.
If the skb does not have enough headroom, using skb_copy might cause the data
buffer to be copied twice (once by skb_copy and once by pskb_expand_head).
Fix this by using skb_clone initially and letting ieee80211_skb_resize sort
out the rest.

The Mesh Control header only includes 0, 1 or 2 addresses. If there is
one address, it should be interpreted as Address 4. If there are 2,
they are interpreted as Addresses 5 and 6 (Address 4 being the 4th
address in the 802.11 header).
The address extension used to hold up to 3 addresses instead of the current 2.
I'm not sure which draft version changed this, but it is very unlikely that it
will change again given the state of the approval process of this draft. See
section 7.1.3.6.3 in current draft (8.0).
Also, note that the extra address that I'm removing was not being used, so this
change has no effect on over-the-air frame formats. But I thought I better
remove it before someone does start using it.

Add a new notification to indicate that a received, unprotected
Deauthentication or Disassociation frame was dropped due to
management frame protection being in use. This notification is
needed to allow user space (e.g., wpa_supplicant) to implement
SA Query procedure to recover from association state mismatch
between an AP and STA.
This is needed to avoid getting stuck in non-working state when MFP
(IEEE 802.11w) is used and a protected Deauthentication or
Disassociation frame is dropped for any reason. After that, the
station would silently discard any unprotected Deauthentication or
Disassociation frame that could be indicating that the AP does not
have association for the STA (when the Reason Code would be 6 or 7).
IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism.

The 802.11 spec states that the STA that generated the last Beacon frame shall
be the STA that response to a probe request. This is important for congestion
reduction when a probe request is received - only 1 node in an adhoc BSS
will transmit a response. While mac80211 drivers should provide the
tx_last_beacon function to report if they transmitted the last beacon many
do not. As an attempt to reduce probe response congestion default this
to 0 such that a node not implementing this capability does not contribute
to unnecessary congestion.
In a modern medium sized office environment I see upwards of 100 probe
requests per second received at a given node from various hardware/OS/drivers
doing zeroconf 'active probing' as opposed to passively listening for beacons.
With a modest 10-node adhoc network consisting of drivers that do not implement
this tx_last_beacon feature, I have seen this result in the simultaneous xmit
of probe responses accumulating to 500 probe responses per second because of
collisions which brings the adhoc network to its knees as well as causes
needless congestion.

On suspend, there might be usb wireless drivers which wrongly trigger
the warning in ieee80211_work_work. If an usb driver doesn't have a
suspend hook, the usb stack will disconnect the device. On disconnect,
a mac80211 driver calls ieee80211_unregister_hw, which calls dev_close,
which calls ieee80211_stop, and in the end calls ieee80211_work_purge->
ieee80211_work_work.
The problem is that this call to ieee80211_work_purge comes after
mac80211 is suspended, triggering the warning even when we don't have
work queued in work_list (the expected case when already suspended),
because it always calls ieee80211_work_work.
So, just call ieee80211_work_work in ieee80211_work_purge if we really
have to abort work. This addresses the warning reported at
https://bugzilla.kernel.org/show_bug.cgi?id=24402

dev_open will eventually call ieee80211_ibss_join which sets up the
skb used for beacons/probe-responses however it is possible to
receive beacons that attempt to merge before this occurs causing
a null pointer dereference. Check ssid_len as that is the last
thing set in ieee80211_ibss_join.
This occurs quite easily in the presence of adhoc nodes with hidden SSID's

Fix this by making a local copy of shared skbs prior to mangeling them.
To avoid copying the skb unnecessarily move the skb_copy call below the
checks that don't need write access to the skb.
Also, move the assignment of nh_pos and h_pos below the skb_copy to point
to the correct skb.
It would be possible to avoid another resize of the copied skb by using
skb_copy_expand instead of skb_copy but that would make the patch more
complex. Also, shared skbs are a corner case right now, so the resize
shouldn't matter much.

mac80211 uses pm_qos (/dev/network_latency) in order to determine the
dynamic ps timeout (or disable the dynamic-ps at all in some cases).
commit ff616381 added a comparison for the current network_latency
against one high value (1900ms), and against the default value
(2000sec, rather than the commented 2sec).
however, the representation of 1900ms was incorrect:
1900ms = 1900000us ( != 1900000000 )
fix it by using USEC_TO_MSEC/SEC consts.

Extend nl80211 to report an exponential weighted moving average (EWMA) of the
signal value. Since the signal value usually fluctuates between different
packets, an average can be more useful than the value of the last packet.
This uses the recently added generic EWMA library function.

Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.
Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.
We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.
In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

cfg80211 used to do all its bookkeeping in
the notifier, but some new stuff will have
to use local variables so make the callback
return the netdev pointer.
