Johannes Berg 80e83da7eb iwlagn: dynamically allocate & reflect calibration data
This makes handling the calibration data more generic
and no longer requires updating IWL_CALIB_MAX when a
new uCode comes with more calibration packets. Since
we just copy the data back, there's also no need for
understanding which calibration we received -- we can
just reflect it back to the runtime uCode.

Johannes Berg c27bdc84d6 iwlagn: remove calibration knowledge
The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

Nick Kossifidis b4cfb5d574 ath5k: Renumber hw queue ids
According to documentation higher DCUs have higher priority and should
be used for beacons and CAB traffic. More specifically DCU 9 should be
used for beacons and DCU 8 for CAB traffic, I assumed DCU 7 should be
OK for UAPSD traffic.

Note that DCU 8 and 9 are special because they can only be mapped to a single
QCU each but since we use a 1:1 mapping between QCUs and DCUs anyway we don't
have to change much.

P.S. I also did a few related cleanups on qcu.c and ath5k.h

in some cases when the card doesn't come with the laptop, EEPROM configuration

Nick Kossifidis ce169aca0d ath5k: Calibration re-work
Noise floor calibration does not interfere with traffic and should run more
often as part of our "short calibration". The full calibration is not the
noise floor calibration but the AGC + Gain_F (on RF5111 and RF5112) calibration
and should run less often because it does interfere with traffic.

So

Short calibration -> I/Q & NF Calibration
Long calibration -> Short + AGC + Gain_F

This patch was for some time on my pub/ dir on www.kernel.org and has been tested
by a few people and me. I think it's O.K. to go in.

I also changed ah_calibration to ah_iq_cal_needed to make more sense.

Nick Kossifidis 7ff7c82ee4 ath5k: Switch from read-and-clear to write-to-clear method when handling PISR/SISR registers
Since card has 12 tx queues and we want to keep track of the interrupts
per queue we can't fit all these interrupt bits on a single register.
So we have 5 registers, the primary interrupt status register (PISR) and
the 4 secondary interupt status registers (SISRs).

In order to be able to read them all at once (atomic operation) Atheros
introduced the Read-And-Clear registers to make things easier. So when
reading RAC_PISR register, hw does a read on PISR and all SISRs, returns
the value of PISR, copies all SISR values to their shadow copies (RAC_SISRx)
and clears PISR and SISRs. This saves us from reading PISR/SISRs in a sequence.

So far we 've used this approach and MadWiFi/Windows driver etc also used it
for years.

It turns out this operation is not atomic after all (at least not on all cards)
That means it's possible to loose some interrupts because they came after the
copy step and hw cleared them on the clean step !

That's probably the reason we got missed beacons, got stuck queues etc and
couldn't figure out what was going on.

With this patch we switch from RaC operation to an alternative method (that
makes more sense IMHO anyway, I just chose to be on the safe side so far).
Instead of reading RAC registers, we read the normal PISR/SISR registers and
clear any bits we got by writing them back on the register. This will clear only
the bits we got on our read step and leave any new bits unaffected (at least
that's what docs say). So if any new interrupts come up we won't miss it.

I've tested this with an AR5213 and an AR2425 and it seems O.K.

Many thanks to Adrian Chadd for debuging this and reviewing the patch !

v2: Make sure we don't clear PISR bits that map to SISR generated interrupts
(added a comment on the code for this)

Arend van Spriel 4c6e869d2e brcm80211: fmac: simplify the brcmf_sdioh_request_buffer() function
The function is only called with sk_buff parameter being non-zero so
the prototype does not need to support passing a char buffer any longer.
When the function is called with a NULL sk_buff parameter it returns
-EINVAL now.

Rajkumar Manoharan a261f0e965 ath9k_hw: Fix minimum CTL power for each runtime mode
The conformance test limits (CTL) for each regulatory domains
(FCC/ETSI/MKK) are programmed for each runtime modes (11B,11G,
HT20 and HT40) in EEPROM. The lowest ctledge power value of a
particular running mode should not be used while computing
ctledge power for a different running mode.(i.e 11G's min ctledge
power should not be used while computing ctledge power for HT20).

Currently, the code does not handle this properly which would
result in incorrect txpowers in certain cases. So reset the
twiceMaxEdgePower to the default while computing min ctlegepower
for every mode.

Nikolay Martynov 4eb287a404 ath9k: improve ath_tx_aggr_stop to avoid TID stuck in cleanup state
When tx agg is being stopped TID is flushed using ath_tx_flush_tid. It
is possible that ath_tx_flush_tid completelly flushes TID (if all
packets in this TID have already been retried). If this happened
ath_tx_aggr_stop would leave TID in cleanup state permanently.
Fix this by making ath_tx_flush_tid remove AGGR_ADDBA_COMPLETE and
AGGR_CLEANUP flags from TID status if TID is empty.

Larry Finger abfabc9b48 rtlwifi: rtl8192cu: Fix endianian issues
Driver rtlwifi fails on a big-endian host.

These changes have been tested on a Mac PowerBook G4, which has
a PPC processor.

Although this patch touches some of the code that will affect endian
issues on PCI hardware through drivers rtl8192ce, rtl8192se, and
rtl8192de, these have not been tested due to lack of suitable hardware.

Gertjan van Wingerde ed66ba472a rt2x00: Fix sleep-while-atomic bug in powersaving code.
The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.

Fix this by moving the call to rt2x00lib_config to a workqueue call.

Venkataraman, Meenakshi 383b0874ab iwlwifi: fix rate-scaling algorithm for BT combo devices
iwlwifi tries to avoid using antenna B in BT combo devices when BT
is active. A bug in the rate-scaling algorithm was causing the combo
device to never attempt MIMO rates. Fix the algorithm to
opportunistically try MIMO rates when BT traffic is low.

Johannes Berg a69cd040d0 iwlagn: explicitly program P2P QoS parameters
In P2P device mode, the device needs to have valid
QoS parameters. We currently have those because we
program parameters from any virtual interface into
all contexts, but not only do we want to get rid of
this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.

Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.

This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.

Johannes Berg aed0fd4acd iwlagn: fix NULL ptr deref when reprogramming sta w/o LQ
Reinette reports a crash in iwl_reprogram_ap_sta(). The
debugging shows:

  b1 16    mov    $0x16,%cl
 *f3 a5    rep movsl %ds     <-- trapping instruction:(%rsi),%es:(%rdi)

which is a memcpy of 22 (0x16) words (movsl). this points
to "priv->stations[sta_id].lq" being NULL since that is
the memcpy() of that size here.

The only way I see for this to happen is if we try to
do some RXON reprogramming while connecting to an AP,
after tx_sync() but before full setup, but that seems
like something that might very well happen.

Fix this by checking if the LQ is present and only then
reprogramming it.

Todd Previte b36b110c57 iwlwifi: Suppress noisy syslog messages when RF_KILL switch engaged
When a station is associated with an AP and the RF_KILL switch is engaged,
numerous error messages were sent to the system log. The error messages
were the result of the failure(s) of the various submodules to perform
their tasks after the radios were disabled.

To resolve this situation, the messages were modified to use a new macro,
IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages
to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO
is '1'. For all other cases, the error messages resulting from an RFKILL
event will not be sent to the system log. Messages logged because of an
RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of
the error.

Driver don't need to worry about it.

In mwifiex driver, we use the private area just to store band
information(u8). We don't allocate memory explicitly and store
it's pointer in bss->priv. Hence we don't have any cleanup work
to do in free_priv handler. Currently we try to free the allocated
private area in free_priv handler which is not correct.

Emmanuel Grumbach 43e5885658 iwlwifi: avoid a panic when unloading the module with RF Kill
When HW RF kill switch is set to kill the radio, our NIC issues an
interrupt after we stop the APM module. When we unload the module,
the driver disables and cleans the interrupts before stopping the
APM. So we have a real interrupt (inta not zero) pending.
When this interrupts pops up the tasklet has already been killed
and we crash.

Here is a logical description of the flow:

disable and clean interrupts
synchronize interrupts
kill the tasklet

stop the APM <<== creates an RF kill interrupt

free_irq <<== somehow our ISR is called here and we crash

Here is the panic message:

Vasanthakumar Thiagarajan 8cb6d9915f ath6kl: Fix error in writing create_qos debugfs
100 bytes are allocated to store the parameters which are needed
to create a priority stream. These 100 bytes are not sufficiant and
throws error when running the following command.

echo "6 2 3 1 1 9999999 9999999 9999999 7777777 0 6 45000 200 56789000
 56789000 5678900 0 0 9999999 20000 0" > create_qos

179 bytes are needed when the following vlaues are given so that
a maximum possible value in that data type can be given in decimal.

echo "255 255 255 255 255 4294967295 4294967295 4294967295 4294967295
 4294967295 255 65535 65535 4294967295 4294967295 4294967295 4294967295
 4294967295 4294967295 4294967295 4294967295" > create_qos

Following takes 187 bytes when given in hex

echo "0xff 0xff 0xff 0xff 0xff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff
 0xff 0xffff 0xffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff 0xffffffff
 0xffffffff 0xffffffff" > create_qos

Increase the size to 200 bytes so that it can hold upto the maximum
value possible for that data type.

Vasanthakumar Thiagarajan a29517ce40 ath6kl: Fix tx packet drop in AP mode with bridge
skb is dropped in ath6kl_data_tx() when the headroom in skb
is insufficient. We hit this condition for every skb in AP mode
which is used with bridge, so all tx packets are getting dropped
when tried to send traffic to wireless client from bridge. Fix
this by reallocating the headroom instead of dropping the skb
when it has lesser headroom than needed.

Raja Mani 0737237411 ath6kl: Remove WARN_ON msg in Suspend path
In the current code, WOW resume is executed first from RX path
and ar->state is moved to ATH6KL_STATE_ON. When platform calls
ath6kl_sdio_resume() in CFG resume context, that time ar->state
could have moved to ON state. Printing WARN_ON(1) is void in
this context. Hence removing this.

Once WOW resume is removed from RX path, This WARN_ON msg can be
reverted.

Raja Mani a918fb3cc6 ath6kl: Perform WOW resume in RX path in case of SDIO IRQ wake up
The target triggers sdio data line to wake up the host when
WOW pattern matches. This causes sdio irq handler is being
executed in the host side which internally hits ath6kl's RX path.

WOW resume should happen before start processing any data from
the target. So it's required to perform WOW resume in RX path.

This area needs bit rework to avoid WOW resume in RX path,
As of now it's fine to have this model, rework will be done later.

cfg80211 layer provides user defined wow parameters like Filter options, Patterns,
Pattern's mask, etc via "struct cfg80211_wowlan *wow" to suspend function.

Right now, this wowlan parameter is not handled in __ath6kl_cfg80211_suspend func.
This parameter has to be passed to HIF layer, So that it can be passed back to
ath6kl's cfg interface layer when WOW mode is selected.
