My patch "mac80211: correctly place aMPDU RX reorder code"
uses an skb queue for MPDUs that were released from the
buffer. I intentially didn't initialise and use the skb
queue's spinlock, but in this place forgot that the code
variant that doesn't touch the spinlock is needed.
Thanks to Christian Lamparter for quickly spotting the
bug in the backtrace Reinette reported.

Wifi and wimax coexistence mode is set by wifi at boot time. There can be
several modes, defined by priority tables. User space components can decide
which one to select by writing to /sys/module/iwmc3200wifi/parameters/wiwi
with this patch, before bringing the interface up.

The driver version number is a remnant from when there was an out-of-tree
iwlwifi driver. Now that the driver forms part of kernel source we do not
need a separate driver version. Instead, we now use the kernel version as
driver version. We maintain the previous tags used to indicate which
components the driver has been compiled with.

An earlier optimization on removing unnecessary traffic on cooked
monitor interfaces ("mac80211: reduce the amount of unnecessary traffic
on cooked monitor interfaces ") ended up removing quite a bit more
than just unnecessary traffic. It was not supposed to remove TX status
reporting for injected frames, but ended up doing it by checking the
injected flag in skb->cb only after that field had been cleared with
memset.. Fix this by taking a local copy of the injected flag before
skb->cb is cleared.
This broke user space applications that depend on getting TX status
notifications for injected data frames. For example, STA inactivity
poll from hostapd did not work and ended up kicking out stations even
if they were still present.

I've just noticed that some events are no longer propagated
for some wireless drivers. Basically, SET request with a extra payload
for driver without commit handler. The fix is pretty simple, see
attached.
Actually, a few lines below this line, you will see that the
event generation for simple SET (iwpoint-less ?) is done properly,
and this other event generation does not need fixing.

For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43legacy_status()
returns a value of 2 (B43legacy_STAT_STARTED); however, one finds that
the driver is unable to associate after resuming from hibernation unless
this routine returns 1. To satisfy both conditions, the routine is rewritten
to return TRUE whenever b43legacy_status() returns a value < 2.
This patch fixes the second problem listed in the postings for Red Hat
Bugzilla #538523.

The routine b43_is_hw_radio_enabled() has long been a problem.
For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43_status()
returns a value of 2 (B43_STAT_STARTED) (BUG 14181). Fixing that
results in Bug 14538 in which the driver is unable to reassociate
after resuming from hibernation because b43_status() returns 0.
The correct fix would be to determine why the status is 0; however,
I have not yet found why that happens. The correct value is found for
my device, which has PHY revision >= 3.
Returning TRUE when the PHY revision < 3 and b43_status() returns 0 fixes
the regression for 2.6.32.
This patch fixes the problem in Red Hat Bugzilla #538523.

In my setups, ath9k's debugfs files are most of the time much more
useful than the messages generated by enabling CONFIG_ATH_DEBUG along
with the right debug flags.
Since CONFIG_ATH_DEBUG comes with a noticeable overhead on embedded

that option.

As indicated by the comment, the aMPDU RX reorder code
should logically be after ieee80211_rx_h_check(). The
previous patch moved the code there, and this patch now
hooks it up in that place by introducing a list of skbs
that are then processed by the remaining handlers. The
list may be empty if the function is buffering the skb
to release it later.
The only change needed to the RX data is that the crypto
handler needs to clear the key that may be set from a
previous loop iteration, and that not everything can be
in the rx flags now.

This code should be part of RX handlers, so move it
to the place where it belongs without changing it.
A follow-up patch will do the changes to hook it up.
The sole purpose of this code move is to make the
other patch readable, it doesn't change the code at
all except that it now requires a different static
function declaration (which will go away too).

This patch moves the works cleanup, scan and events to a cfg80211
dedicated workqueue.
Platform driver like eeepc-laptop ought to use works to rfkill (as
new rfkill does lock in rfkill_unregister and the platform driver is
called from rfkill_switch_all which also lock the same mutex).
This raise a new issue in itself that the work scheduled by the platform
driver to the global worqueue calls wiphy_unregister which flush_work
scan and event works (which thus flush works on the global workqueue inside
a work on the global workqueue) and also put on hold the wdev_cleanup_work
(which prevents the dev_put on netdev thus indefinite Usage count error on
wifi device).

Atheros single stream AR9285 and AR9271 have half the PCU TX FIFO
buffer size of that of dual stream devices. Dual stream devices
have a max PCU TX FIFO size of 8 KB while single stream devices
have 4 KB. Single stream devices have an issue though and require
hardware only to use half of the amount of its capable PCU TX FIFO
size, 2 KB and this requires a change in software.
Technically a change would not have been required (except for frame
burst considerations of 128 bytes) if these devices would have been
able to use the full 4 KB of the PCU TX FIFO size but our systems
engineers recommend 2 KB to be used only. We enforce this through
software by reducing the max frame triggger level to 2 KB.
Fixing the max frame trigger level should then have a few benefits:
* The PER will now be adjusted as designed for underruns when the
max trigger level is reached. This should help alleviate the
bus as the rate control algorithm chooses a slower rate which
should ensure frames are transmitted properly under high system
bus load.
* The poll we use on our TX queues should now trigger and work
as designed for single stream devices. The hardware passes
data from each TX queue on the PCU TX FIFO queue respecting each
queue's priority. The new trigger level ensures this seeding of
the PCU TX FIFO queue occurs as designed which could mean avoiding
false resets and actually reseting hw correctly when a TX queue
is indeed stuck.
* Some undocumented / unsupported behaviour could have been triggered
when the max trigger level level was being set to 4 KB on single
stream devices. Its not clear what this issue was to me yet.

Software padding is done on the TX path and software unpadding is done on the
RX path. This patch corrects the position where the padding occurs. A specific
function computes the pad position and this function is used in the TX and RX
path. This patch has been tested by generating every possible 802.11 frames
with every possible frame_control field and a varying length. This patch is
useful for analyzing non standard 802.11 frames going over the air

When mac80211 was telling us to go into Powersave we listened
and immediately turned RX off. This meant hardware would not
see the ACKs from the AP we're associated with and hardware
we'd end up retransmiting the null data frame in a loop
helplessly.
Fix this by keeping track of the transmitted nullfunc frames
and only when we are sure the AP has sent back an ACK do we
go ahead and shut RX off.

The tx concatenation option works fine now, we no longer need the debugging

To support 802.11n Tx aggregation support with iwmc3200 wifi, we have to
handle the UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification from the UMAC.
Before sending an AddBA, the UMAC synchronizes with the host in order to
know what is the last Tx frame it's supposed to receive before it will be
able to start the actual aggregation session.
We thus have to keep track of the last sequence number that is scheduled
for transmission on a particular RAxTID, send an answer to the UMAC with
this sequence number. The UMAC then does the BA negociation and once it's
done with it sends a new UMAC_CMD_OPCODE_STOP_RESUME_STA_TX notification
to let us know that we can resume the Tx flow on the specified RAxTID.

When we're down, we shouldnt try to set the UMAC power limit. We just return 0
instead, and cfg80211 toggles the soft rfkill state.
