2a5783b817 ath9k: don't strip mic on non-encrypted frames in tkip
Fix the following bug: in tkip mode, qos-null ps on/off packets
are dropped due to incorrect packet length so that ath9k softap
can't handle powersave state transition of peer STA correctly.

75acd5a82a ath9k: fix TX power reporting on AR9003 chips
The current code unconditionally reads the target
power values for all modes from the EEPROM. However
In 'ar9003_hw_set_power_per_rate_table' the regulatory
caps are applied only on a mode specific subset of the
power values.

The reported TX power level is calculated from the
maximum of the power values. Because some of these
values are uncapped in certain cases, the reported
TX power will be wrong.

On the older chipset, we don't have such problems
because only the mode specific subset of the power
levels are retrieved from the EEPROM on those. Do
the same for the AR9003 chips to fix the issue.

dd44731989 ipw2200: Fix race condition in the command completion acknowledge
Driver incorrectly validates command completion: instead of waiting
for a command to be acknowledged it continues execution.  Most of the
time driver gets acknowledge of the command completion in a tasklet
before it executes the next one. But sometimes it sends the next
command before it gets acknowledge for the previous one. In such a
case one of the following error messages appear in the log:

Failed to send SYSTEM_CONFIG: Already sending a command.
Failed to send ASSOCIATE: Already sending a command.
Failed to send TX_POWER: Already sending a command.

After that you need to reload the driver to get it working again.

This bug occurs during roaming (reported by Sam Varshavchik)
https://bugzilla.redhat.com/show_bug.cgi?id=738508
and machine booting (reported by Tom Gundersen and Mads Kiilerich)
https://bugs.archlinux.org/task/28097
https://bugzilla.redhat.com/show_bug.cgi?id=802106

This patch doesn't fix the delay issue during firmware load.

83722bd4ae ath9k: fix tx power settings for AR9287
The 'ath9k_hw_update_regulatory_maxpower'
helper function has been introduced by
commit a55f858852
(ath9k_hw: Cleanup TX power calculation for AR9287).

Updating of the max_power_level value has been moved
into the helper function in that change, however the
removed code from 'ath9k_hw_ar9287_set_txpower' has
not been replaced with a call of the new helper
function.

Due to that missing call, retrieving tx power for 2x2
and 3x3 chainmask is not handled properly. During the
calculation of the tx power for 2x2 and 3x3 chainmasks
the values are reduced. Those reductions must be
compensated during retrieving.

Fix this by adding the missing call of the helper
function.

64ea57d0c7 ath9k: add an extra boolean parameter to ath9k_hw_apply_txpower
In order to unifying regulatory limit handling
commit ca2c68cc7b
(ath9k_hw: clean up tx power handling) introduced
a new helper function 'ath9k_hw_apply_txpower',
and the direct calls of 'ah->eep_ops->set_txpower'
has been replaced by a call of the helper function.

This caused a change in the behaviour of the
'ath9k_hw_set_txpowerlimit' function. The purpose
of that function is to calculate and store the
rate txpower table and the regulatory limit without
touching the hardware registers. Before the commit,
the 'test' parameter of the function was passed to
the 'ah->eep_ops->set_txpower'. Now the calling of
the 'set_txpower' function happens indirectly through
'ath9k_hw_apply_txpower', so the 'test' argument of
the 'set_txpower' is always 'false'.

This patch restores the original behaviour of
'ath9k_hw_set_txpowerlimit' by adding a new
argument to 'ath9k_hw_apply_txpower.'

bf8440e6a6 iwlwifi: improve TX cache footprint
Having cmd[], meta[] and skbs[] as separate arrays
in the TX queue structure is cache inefficient as
we need the data for a given entry together.

To improve this, create an array with these three
members (allocate meta as part of that struct) so
we have the data we need together located together
improving cache footprint.

The downside is that we need to allocate a lot of
memory in one chunk, about 10KiB (on 64-bit) which
isn't very efficient.

3b8ffc6a22 ath6kl: Configure probed SSID list consistently
Set max_scan_ssids and max_sched_scan_ssids to same value. These use the
same probed SSID list, so there is no point in using different maximum
number of SSIDs.

Clear probed SSID entries that are not used. This was already done for
sched_scan, but not for scan. Be consistent and clear the table for both
cases to avoid leaving bogus entries.

In addition, share the same function for setting the probed SSIDs for
scan and sched_scan paths. This fixes setting of wildcard SSID flag
(ANY_SSID_FLAG) and changes the scan path to use probed SSID index
consistently (i.e., start with 0 similarly to sched_scan; firmware
will handle the needed internal mapping).

b5abcf0219 mwifiex: corrections in timestamp related code
We get two timing related fields for each bss from firmware in scan
results.
1) timestamp - Actual timestamp information in probe response/beacon
2) network_tsf - firmware's TSF value at the time the beacon or probe
response was received.
Both are needed while associating by firmware.

The patch takes care of following things.
1) We should pass "timestamp" to cfg80211_inform_bss(), but currently
"network_tsf" is being provided. This error is corrected here.
2) Rename "network_tsf" to "fw_tsf"
3) Make use of u64 variable instead of an array of u8/u32 to save
parsed "timestamp" information.
4) Use timestamp provided to stack in scan results using
cfg80211_inform_bss() while associating. (bss->tsf)
5) Allocate space to save fw_tsf in "priv" of cfg80211_bss
and retrieve it while associating.

534111c78c libertas: add asynchronous firmware loading capability
As described at
http://article.gmane.org/gmane.linux.kernel.wireless.general/86084
libertas is taking a long time to load because it loads firmware
during module loading.

Add a new API for interface drivers to load their firmware
asynchronously. The same semantics of the firmware table are followed
like before.

Interface drivers will be converted in follow-up patches, then we can
remove the old, synchronous firmware loading function.

Remove the ability to pass module parameters with firmware filenames
for USB and SDIO interfaces.

Remove the ability to pass custom "user" filenames to lbs_get_firmware().

Remove the ability to reprogram internal device memory with a different
firmware from the USB driver (we don't know of any users), and simplify
the OLPC firmware loading quirk to simply placing the OLPC firmware
at the top of the list (we don't know of any users other than OLPC).

Move lbs_get_firmware() into its own file.

These simplifications should have no real-life effect but make the

be03d4a45c rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails
There are connection stalls or very poor throughputs with rt2800
hardware using 802.11n in AP mode since patch "mac80211: retry sending
failed BAR frames later instead of tearing down aggr"[1][2].

Since rt2800 hardware is not able to correctly report the tx status of
BAR frames, this patch removes as workaround the existing error handling
on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails.

As a result, most wifi clients (aside from Intel STAs on Windows)
instead will timeout now the reorder buffer and request the lost frame
again.

The correct solution would be, to tear down BA session on AP side.

This patch was born on the basis of "[RFT] rt2x00: Tear down BA
session on QoS frame failure"[3].

Thanks to Helmut Schaa for his support!

0479c19d9f iwlwifi: remove uCode alternatives mechanism
We've never released firmware using the alternatives
mechanism and our build process makes that difficult
anyway. This means that in every file we have ever
built (except maybe by hand for testing) the listed
alternative was 0. Make the alternative field in the
TLVs part of the TLV number (thus expanding that to
32 bits); this gives us more TLV numbers (not really
needed) and more importantly protects against rogue
firmware files that actually do use the alternatives
mechanism -- those will now be rejected since they
don't contain any valid TLVs.

84965795b2 iwlwifi: remove no_sleep_autoadjust
My original idea with this was to adjust the sleep
pattern of the uCode based on the maximum network
latency userspace asked for. Due to nobody wanting
to test it, this logic was disabled by default. It
seems the time has come to remove it, since it's
not only always disabled but there also don't seem
to be any applications that actually request a max
network latency.

Programming these values to the HW results in undesirable
behavior - for example, large number of delimiter/data
underruns are seen in AES-CCMP mode. Also, registers like
AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX
power table is programmed to the HW, and frames being transmitted
end up being looped back to the RX engine, an example being beacon
frames in IBSS mode.

Remove this table for now - this fixes CCMP performance and general
IBSS usage.

There have been reports about not being able to use access-points
on channel 12 and 13 or having connectivity issues when these channels
were part of the selected regulatory domain. Upon switching to these
channels the brcmsmac driver suspends the transmit dma fifos. This
patch resumes them upon handing over the first received beacon to
mac80211.

This patch is to be applied to the stable tree for kernel versions
3.2 and 3.3.

11483b5c22 iwlwifi: move eeprom into priv
The whole code around eeprom is distributed
across whole bunch of different files, most
of which belong to the to-be-DVM code. As a
result, it is currently very hard to split
out the EEPROM code to be generic. However,
it is also quite unlikely that the current
EEPROM code will be needed by the MVM code
as that has different mechanisms to query
the EEPROM (it does so through the uCode.)

So, at least temporarily, move everything
into priv. If it becomes necessary to use
the code from MVM, we will have to split it
out, but then it's also easier since we'll
know what pieces we need.

9e295116bb iwlwifi: move hw_params into priv
The hw_params are mostly values that are
derived from the actual hardware config.
As such, while it is possible that MVM
will require similar ones, it makes more
sense -- at least for now -- to put them
into the DVM struct.

7c5ba4a830 iwlwifi: move queue watchdog into transport
This removes one of the two sources of device
restarts in the upper layer -- those are a bit
inconvenient because normal restarts originate
in the transport. By moving the watchdog down
it can be treated the same.

Also rewrite the watchdog logic. Timers are
much more efficient when they never fire, so
instead firing a timer every 500ms set up a
timer for each TX queue and fire it only when
the queue is really stuck. This avoids the CPU
waking up when everything is working well.

While at it, remove the wd_disable config item
and replace it by simply setting wd_timeout to
IWL_WATCHHDOG_DISABLED (0).

4b6f1dd6a6 mac80211: add explicit monitor interface if needed
The queue mapping redesign that I'm planning to do
will break pure injection unless we handle monitor
interfaces explicitly. One possible option would
be to have the driver tell mac80211 about monitor
mode queues etc., but that would duplicate the API
since we already need to have queue assignments
handled per virtual interface.

So in order to solve this, have a virtual monitor
interface that is added whenever all active vifs
are monitors. We could also use the state of one
of the monitor interfaces, but managing that would
be complicated, so allocate separate state.

a7959c1394 rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routine
The current version of rtlwifi for USB operations uses kmalloc to
acquire a 32-bit buffer for each read of the device. When
_usb_read_sync() is called with the rcu_lock held, the result is
a "sleeping function called from invalid context" BUG. This is
reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775.
The first case has the lock originating from within rtlwifi and could
be fixed by rearranging the locking; however, the second originates from
within mac80211. The kmalloc() call is removed from _usb_read_sync()
by creating a ring buffer pointer in the private area and
allocating the buffer data in the probe routine.

6f407e5bc7 wl12xx: adaptive sched scan dwell times
Set the dwell times for sched scan according to the number
of probe requests which are going to be transmitted.
This should fix the too short dwell time problem which
prevented some of the probe requests from being transmitted
in cases of high number of SSIDs (10+) to be actively sched scanned.
However, in the common case of having up to 1-2 SSIDs that
require active scan, the dwell time would be kept to a minimum
which should conserve power. This is important as sched scan
also runs periodically while the host is suspended and there's
great importance to keep power consumption as low as possible.

e3ec26de90 iwlwifi: remove firmware info from iwl_shared
With error logging now completely handled in
the op_mode, the transport layer does not
need to know information about the loaded
firmware.

Remove this state information from the
iwl_shared data structure.

a42506eb27 iwlwifi: move ucode_type from shared to op_mode
This variable holds the ucode currently
running on the device; which is determined by
op_mode, so move this parameter there.

Also, the name of the variable is a bit
misleading, so rename it to cur_ucode.

2fdfc476cf iwlwifi: move ucode error log reporting to op_mode
Error log reporting does not belong to the
transport layer, but to the op_mode loading
the ucode, as it is the entity which knows
about the ucode loaded, and what the error
information means.

Move device logging pointers from the
transport layer to op_mode.

With this change, transport layer only
reports an error to the op_mode, which will
figure out what to do with the error. This
causes the driver to now dump out error logs
when the command queue is stuck as well.

Also, move the debugfs entry for event logs
out of the transport layer and into op_mode.
