Rajkumar Manoharan c2ba334246 ath9k_hw: Restore ANI registers to default during partial reset for AR9271
For AR9271 chips, if partial reset is done while scanning, the cycpwrThr1
will be set to maximum. This causes the degrade in DL throughput.
So restore the ANI registers to default during the partial reset.

This algorithm chooses the best main and alt lna out of
LNA1, LNA2, LNA1+LNA2 and LNA1-LNA2 to improve rx for single

is only one antenna is connected with AR9285.

Wey-Yi Guy f7322f8f05 iwlagn: open/close envlope to force move BT state machine
In uCode, BT state machine need to receive open envlope
command before perform calibration; followed by close envlope
command to move to next stage.

Since Linux has two separated uCode, one for init and the second
one for runtime; we use open envlope commands for init uCode to
indicate we are ready to perform calibration operation.
But for runtime uCode, we are not doing any init calibration,
so we issue open/close envlope commands to force uCode move to
"BT COEX ON" state.

Ivo van Doorn cd35a39121 rt2x00: Cleanup rt2x00usb_watchdog_reset_tx
rt2x00usb_watchdog_reset_tx performs the same task
as rt2x00usb_kill_tx_queue, with the only difference
is that it waits for all entries to be returned to
the driver and for all frames the status has been
reported to mac80211.

We can easily split this task by calling rt2x00usb_kill_tx_queue,
sleep for a short period and invoke the TX status reporting
function. By adding the sleep() to the kill_entry we make sure
that even during shutdown we guarentee the entry has been killed when
the function returns. To make this work correctly the interrupt
handlers have to be updated to prevent checking for the RADIO_ENABLED
flag too early which prevents the ownership of the entry to be reset.
Additionally a check for the DEVICE_PRESENT flag is not required but
is nice to prevent race conditions when the device was unplugged.

Additionally rather then calling rt2x00usb_work_txdone() for
status reporting we let the driver perform the TX status reporting
first. If this is not sufficient then rt2x00usb_work_txdone() will
still be used to cleanup the mess.

Ivo van Doorn 652a9dd2a0 rt2x00: Split watchdog check into a DMA and STATUS timeout
The watchdog for rt2800usb triggers frequently causing all URB's
to be canceled often enough to interrupt the normal TX flow.
More research indicated that not the URB upload to the USB host
were hanging, but instead the TX status reports.

To correctly detect what is going on, we introduce Q_INDEX_DMA_DONE
which is an index counter between Q_INDEX_DONE and Q_INDEX and indicates
if the frame has been transfered to the device.

This also requires the rt2x00queue timeout functions to be updated
to differentiate between a DMA timeout (time between Q_INDEX and
Q_INDEX_DMA_DONE timeout) and a STATUS timeout (time between
Q_INDEX_DMA_DONE and Q_INDEX_DONE timeout)

All Q_INDEX_DMA_DONE code was taken from the RFC from
Helmut Schaa <helmut.schaa@googlemail.com> for the implementation
for watchdog for rt2800pci.

Johannes Berg 13bb9483e1 iwlwifi: prepare for PAN queue/fifo assignment
PAN ucode will require a different queue assignment,
in particular queue 9 instead of 4 should be used for
commands.

This is required because the ucode will stop/start
queues 4 and 8 depending on the PAN state, since
queue 8 will be used for PAN multicast (after DTIM).

Ivo van Doorn 8d1331b37d rt2x00: Fix max TX power settings
During initialization each driver reads the default TX power
for each individual channel. However mac80211 only accepts the
maximum value (which is also handled as default value).

As a result, the TX power of the device was being limited to
the default value, which is often quite low compared to the
real maximum acceptable value.

This patch allows each driver to set the maximum value on a
per-channel basis which is forwarded to mac80211. The default
value will be preserved for now, in case we want to update
mac80211 to differentiate between the maximum and default txpower.

This fixes bug complaining about limited TX power values like:

Most callers of the kick_tx_queue and kill_tx_queue already
have the data_queue pointer, so rather then sending the QID
with the given function, when the driver requests a new

send the data_queue pointer directly.

When there's high bluetooth traffic load, there's
little point in trying to aggregate as BT traffic
would disrupt the aggregated frames all the time,
so simply don't start sessions then.

When BT traffic returns to lower levels, the rate
scaling will come here again automatically when
wifi traffic is high enough, and then it will be

To make del_timer_sync() works we have to assure that timer function
does not rearm the timer. To achieve that we cancel timer with
STATUS_EXIT_PENDING bit set in __iwl{3945,}_down function.

Patch also fix priv->txq memory usage after free for iwl3945, because
it move timer cancellation before iwl3945_hw_txq_ctx_free(priv) is called.

When iwl_mac_config() is called by mac80211, the channel pointer
hw->conf->channel can potentially change, resulting in mismatch
band and channel number when configuring RXON command. To avoid
this situation, save the channel pointer in local variables
and validate the channel before using it. Note that priv->mutex
is locked during the whole function so the local variables are safe.

Same change is applied to iwl_mac_channel_switch() since basically
it copies code from iwl_mac_config().

Also removed an outdated comment in the flow.

Like other vendors, p54* devices have a checksum for
the EEPROM descriptor data. This patch enhances the
parser code to generate and verify the data fields,
before initializing the radio-chip on the card.

Note:
	If you have to bootstrap an alternative EEPROM image
	for your device and you don't know how to generate a
	valid crc ccitt checksum, you should take a look at:
	http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

	The "checksum" utility loads a binary p54 EEPROM blob
	(use the -f switch, to skip the check) and applies
	the correct crc automatically.

Andrew Morton b68b3c4d92 drivers/net/wireless/libertas/cfg.c: needs sched.h
i386 allmodconfig:

drivers/net/wireless/libertas/cfg.c: In function 'lbs_scan_worker':
drivers/net/wireless/libertas/cfg.c:722: error: 'TASK_NORMAL' undeclared (first use in this function)
drivers/net/wireless/libertas/cfg.c:722: error: (Each undeclared identifier is reported only once
drivers/net/wireless/libertas/cfg.c:722: error: for each function it appears in.)
drivers/net/wireless/libertas/cfg.c: In function 'lbs_cfg_connect':
drivers/net/wireless/libertas/cfg.c:1267: error: 'TASK_INTERRUPTIBLE' undeclared (first use in this function)
drivers/net/wireless/libertas/cfg.c:1267: error: implicit declaration of function 'signal_pending'
drivers/net/wireless/libertas/cfg.c:1267: error: implicit declaration of function 'schedule_timeout'

So wait.h has a dependency on sched.h, but doesn't include sched.h.  This
patch doesn't fix that.

Johannes Berg 97359d1235 mac80211: use cipher suite selectors
Currently, mac80211 translates the cfg80211
cipher suite selectors into ALG_* values.
That isn't all too useful, and some drivers
benefit from the distinction between WEP40
and WEP104 as well. Therefore, convert it
all to use the cipher suite selectors.
