Subject: wl12xx: set the ELP entry delay to the FW dyn-ps timeout

With PSM handled in FW, the checks in wl1271_elp_work() are always true.
Thus during active traffic we constantly enter and exit ELP (many times
per second). As each ELP exit takes ~10ms, this can have an adverse
effect on throughput and interactivity.
Set the ELP timeout to the dyn-ps timeout. This period is longer and
avoids the above problem. It also makes sense to stay out of ELP while
we are awake on the network, to minimize delays in Tx/Rx. The same thing
was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

Subject: wl12xx: reset link Tx queues when freeing it

Before, the link was first freed (invalidating it in the map), and later
on vif removal, all valid wlvif-related links were reset. Since these
links were already invalid, we failed to reset them.
The bug was made worse by op_stop, which set the tx_queue_count to 0
arbitrarily. This resulted in a negative tx_queue_count in some scenarios.

Fix this by resetting the Tx-queues of a link when freeing it. Add a
WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative
tx_queue_count.

[changed WARN_ON to WARN_ON_ONCE -- Luca]

Subject: wl12xx: avoid starving the system hlid

Re-factor the Tx scheduler so that the system_hlid is taken into account
before restarting an iteration over the wlvifs. Previously this
hlid had a lower priority and would starve if some wlvif had many
packets.
In addition avoid iterating over wlvifs past last_wlvif when performing
the a second pass. If we had packets in those wlvifs they would have
been found earlier.

Subject: wl12xx: set authorized AP on sta_state notification

wl12xx currently looks for AP authorization by registering
a netdev notifier and waiting for the IF_OPER_UP notification,
which is quite cumbersome.

Use the newly introduced sta_state callback (waiting
for assoc -> auth notification) instead, in order to
simplify it.

Subject: wl12xx: configure the correct beacon_interval

We didn't update the beacon interval on association
(or on a change notification when working as sta),
so the default interval (100ms) was always used.

Update the beacon interval according to the bss_conf
before starting the sta role (on association).

Subject: mwifiex: handle auto authentication mode correctly

When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC,
driver tries to connect using open mode. The association is failed
if AP is configured in shared mode.

This patch adds code to try association using shared mode as well if
open mode association fails.

Now since we returned exact error code in association response handler
(instead of -1), corresponding changes are done in
mwifiex_process_cmdresp().

The approach of this change is flawed, as it triggers tx status processing
from more callsites, yet the chips only have one global tx status queue.
Subsequent patches will properly fix the issue that this one tried to address.

Subject: ssb: remove 5GHz antenna gain from sprom

There is no 2.4 GHz or 5GHz antenna gain stored in sprom. The sprom
just stores the gain values for antenna 1 and 2 or 1 to 4 for more
recent sprom versions. On old devices antenna 2 was used for 5 GHz wifi.

Subject: bcma: add support for sprom not found on the device

On SoCs the sprom is stored in the nvram in a special partition on the
flash chip. The nvram contains the sprom for the main bus, but
sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
sprom from the nvram and provide it to the bcma code.

Subject: mwifiex: remove unnecessary struct mwifiex_802_11_ssid

Use struct cfg80211_ssid available in include/net/cfg80211.h
instead of having similar definition in driver.

Subject: mwifiex: fix bug in wildcard scan handling

Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.

When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.

Also, use SSID list pointer provided by stack directly, instead
of copying SSID's to local structure.

Subject: b43: prevent firmware on bcm5354 from taking over wrong GPIO pins

When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent
firmware >= 478.104 it runs out of memory after a very short time in
OpenWrt after doing an active scan or any thing else where packages are
send. This was cased by a gpio misconfiguration, the firmware triggered
the GPIO pins used for buttons on some devices and that caused an other
driver (OpenWrt diag) listening for these buttons irqs to send many
messages to the user space.
This patch fixes the bug for my devices (Asus WL-520GU) and makes it
work with firmware 666.2. Now the firmware just uses LED GPIO pin
number 1 and not the button pins any more.

This is the GPIO Pin layout used on my device, see [0].
GPIO pin layout:
pin#    name    type
0       power   led
1       wlan    led
2       reset   button
3       ses     buttom

This is the nvram configuration output of "nvram show |grep gpio"

related nvram configuration:
wl0gpio2=11
wl0gpio3=11
wl0gpio0=11
wl0gpio1=0x02
reset_gpio=2

Subject: rndis_wlan: integer overflows in rndis_wlan_do_link_up_work()

If "offset" is negative then we can get past this check:
	if (offset > CONTROL_BUFFER_SIZE)
Or if we pick a very high "req_ie_len" then we can get around the check:
	if (offset + req_ie_len > CONTROL_BUFFER_SIZE)

I made "resp_ie_len" and "req_ie_len" unsigned.  I don't know if it was
intentional that they were signed in the original.

Subject: rndis_wlan: make some variables unsigned

These variables can never be less than zero because we cap them in
get_device_pmkids().  Let's make them unsigned here because it's simpler
to not have to worry about negative numbers when we read the code.

Subject: rndis_wlan: fix le16/le32_to_cpu mix up with config.beacon_period

'beacon_period' in 'struct ndis_80211_conf' is __le32 instead of __le16 so
le32_to_cpu must be used instead of le16_to_cpu.

Also correct 'beacon_interval' variables used for passing this value forward
from u16 to u32 and rename those variables 'beacon_period' This is to avoid
confusion because 'beacon_interval' is defined as __le16 at other structure,
'struct ndis_80211_fixed_ies'.

Subject: mwifiex: endian bug in mwifiex_drv_change_adhoc_chan()

In mwifiex_drv_change_adhoc_chan() we pass channel to
mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits.  This
works on little endian systems but not on big endian ones.  I've changed
mwifiex_drv_change_adhoc_chan() to use a 16 bit variable.  This matches
the other functions in the file.

I considered changing mwifiex_change_adhoc_chan() as well but it turns
out that the function isn't implemented so I just removed the
definition.

In the unlikely event of a misread of the USB end point count, the driver

returned by _rtl_usb_init(). In addition, add some logging to indicate
why the condition occurred.

Subject: rtlwifi: Remove extraneous value return

In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe()
never checks the returned value. Thus we can change _rtl_usb_init_sw() to
a void routine. In addition, remove the underscore at the beginning of the
name of the routine.

Subject: rtlwifi: rtl8192c: Prevent sleeping from invalid context in rtl8192cu

When driver rtl8192cu is used with the debug level set to 3 or greater,
the result is "sleeping function called from invalid context" due to
an rcu_read_lock() call in the DM refresh routine in driver rtl8192c.
This lock is not necessary as the USB driver does not use the struct
being protected, thus the lock is set only when a PCI interface is
active.

This bug is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42775.

The usb code defines a structure for counting statistics. However,
it should use the statistics entry provided in brcmf_bus as that is
exposed to the net_device. The usb private statistics counter only
remains with counters for control packets between driver and usb

Subject: brcm80211: fmac: initialize host interface drivers regardless result

The module init function of brcmfmac calls init functions for SDIO and
USB doing driver registration. This patch removes terminating the module
init when a driver registration for one host interface fails.

Subject: ath5k: allow AP and mesh mode to operate simultaneously

This patch allows the possibility of having the mesh point and AP to be operated
simultaneously in one single radio. Previously, mesh point fails to generate the
mesh beacon if virtual AP is created for the same radio.

Subject: rtlwifi: rtl8192ce: Fix loss of receive performance

Driver rtl8192ce when used with the RTL8188CE device would start at about
20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the
symptoms is that the AP would need to retransmit each packet 4 of 5 times
before the driver would acknowledge it. Recovery is possible only by
unloading and reloading the driver. This problem was reported at
https://bugzilla.redhat.com/show_bug.cgi?id=770207.

The problem is due to a missing update of the gain setting.

Subject: iwlwifi: always monitor for stuck queues

If we only monitor while associated, the following
can happen:
 - we're associated, and the queue stuck check
   runs, setting the queue "touch" time to X
 - we disassociate, stopping the monitoring,
   which leaves the time set to X
 - almost 2s later, we associate, and enqueue
   a frame
 - before the frame is transmitted, we monitor
   for stuck queues, and find the time set to
   X, although it is now later than X + 2000ms,
   so we decide that the queue is stuck and
   erroneously restart the device

It happens more with P2P because there we can
go between associated/unassociated frequently.

We should be doing a shift (1 << FLAG_RADIO_DOWN) here before testing
the flag.  As luck would have it, this test works almost correctly.
The current code tests for FLAG_RADIO_OFF instead of FLAG_RADIO_DOWN.

#define FLAG_RADIO_OFF  0       /* User disabling of MAC */
#define FLAG_RADIO_DOWN 1       /* ifup/ifdown disabling of MAC */

Subject: iwlwifi: reduce sta_lock hold time in TX

When we TX, we hold the sta_lock for a long
time, a lot of which isn't needed. Reduce
the time we hold the lock. Note that this
doesn't really change anything as the code
is already under the other spinlock, but it
makes the code easier to read.

Subject: iwlwifi: build some station commands directly

In the powersave related functions we only need
to set a few parameters for the station command
and can otherwise leave it blank -- there's no
need to copy it from the database.

This allows us to not use the sta lock here.

Instead of (ab)using the sta_lock, make the
transport layer lock its own TX queue data
structures with a lock per queue. This also
unifies with the cmd queue lock.

From fa23cb04b38a9950b21ee756e4419a737d496371 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:25 -0800
Subject: iwlwifi: make sta lock private & BH lock

Now that the transport has its own locking,
there's no need to have the sta_lock in the
shared data. Also, it can be a BH lock as
it's not used from IRQ handlers.

From 08ae86ac3f9d9c9a60d2883c82cd72a5c66b94db Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:27 -0800
Subject: iwlwifi: remove shared lock

Some data doesn't need protection, some of the
lock places are simply useless, and some data
can be protected with the mutex instead. Thus
the shared lock can be removed by making those
changes.

Subject: iwlwifi: make EXIT_PENDING depend on mac80211

There's no reason to set EXIT_PENDING when we
start removing the module, as mac80211 will
cleanly shut down the device in this case.
Additionally, there's no point in rejecting
commands to the device when we're cleaning up
as that only leads to unwanted errors from
mac80211 being printed, such as
  failed to remove key (...) from hardware (-16)

Subject: iwlwifi: simplify auth/assoc flow

With mac80211 now giving us station information
(via the sta_state callback) before auth/assoc
we can get rid of tx_sync by adding the station
early for the case of managed interfaces. Keep
AP mode actions the same for now.

As we now get the BSSID early, we can also get
rid of iwl_reprogram_ap_sta().

We can still optimise the number of RXONs we
send to the device, but that can be done later.

From a8bceb392a739321ec20d03a91a86ebdde9c07bb Mon Sep 17 00:00:00 2001

Subject: iwlwifi: remove per-device debug level

There's no need for the per-device debug
level that we expose in debugfs since the
module parameter is writable in sysfs.

At the same time, simplify code by changing
    iwl_get_debug_level(shrd) & IWL_DL_ISR)
to
    iwl_have_debug_level(IWL_DL_ISR)

Subject: iwlwifi: remove SKU from config

There's no SKU override, we always just use
it from EEPROM. As such, we can remove it
from the config and use it in hw_param only.
Since iwl_eeprom_check_sku() really needs
to fill it in also rename that to
iwl_eeprom_init_hw_params().

Subject: iwlwifi: use valid TX/RX antenna from hw_params

It's not really a good idea to write to the
global static configuration. Use the valid
TX/RX antenna information only from the HW
params struct except in the case where the
values from the config are used to override
the values from the EEPROM.

Subject: iwlwifi: clean up (wowlan) suspend flow

In the WoWLAN suspend flow, instead of accessing
registers directly, ask the transport to do the
required setup at the end of suspend. If the
transport doesn't implement this, don't tell the
stack we support WoWLAN.

When the device suspends w/o WoWLAN, mac80211
will have stopped it already, which has already
called iwl_apm_stop() via stop_hw(). Thus, it
isn't necessary to call it again in pcie_suspend
and we can simply do nothing there.

This unifies the regular and WoWLAN suspend.

Subject: iwlwifi: use ieee80211_tx_status

We currently use the _irqsafe version, but that
isn't recommended together with ieee80211_rx()
as it can cause races. If the device reports
a TX-status and RX in that order then with the
current combination mac80211 might process them
in the other order, which can cause issues with
powersaving clients.

Use ieee80211_tx_status() to avoid this race.
Since we don't want to call it with locks held,
process the frame queues later -- this is fine
as they are on the stack.

From 65b94a4abfd55b3304be25ffed9832455d41e1dd Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:38 -0800
Subject: iwlwifi: pass response packet directly

When CMD_WANT_SKB is set for a (synchronous)
command, the response is passed back to the
caller which is then responsible for freeing
it. Make this more abstract with real API,
passing directly the response packet in the
new cmd.resp_pkt member and also introduce
iwl_free_resp() to free the pages -- this
way the upper layers don't have to directly
touch the page implementation.

NOTE: This breaks IDI -- the new code isn't reflected there yet!

Subject: iwlwifi: don't pass iwl_rx_mem_buffer to upper layers

struct iwl_rx_mem_buffer implementation details
(DMA address, list pointers) that the upper
layers don't need. Introduce iwl_rx_cmd_buffer
that is passed upstream and only contains the
needed data (the page). Additionally, access
this data only via accessor functions, allowing
us to change the implementation in the future.
These accessors are rxb_addr() (as before) and
rxb_steal_page() to take ownership of the data.

the code for it can be close to where it's
used rather than in iwl-shared.h.

Subject: iwlwifi: fix station HT parameters

My patch "iwlwifi: simplify auth/assoc flow"
caused a serious throughput degradation due
to me forgetting that there are HT settings
in the station table. To restore throughput,
set these parameters correctly when the sta
moves to assoc state.

This patch should probably be merged with
the auth/assoc redesign patch for upstream.
In that case, this paragraph should be added
to the commit log as the third paragraph
(before talking about RXON):

However, as we only get the station HT data
when the station moves into assoc state, we
also need to program this into the device
(and copy it into our database) then.

Subject: ath5k: do not stop queues for full calibration

Some calibration types interfere with tx activity, but the queue stop does
not prevent that. In fact, some calibration types need tx activity to properly
function, so stopping the queues for them is counterproductive.
In some tests this patch has been shown to improve stability, especially in
AP or ad-hoc mode.

Subject: ath5k: do not re-run AGC calibration periodically

All other Atheros drivers run the AGC gain calibration and DC offset
calibration only after reset. Running them periodically has caused stability
issues on some (primarily AR2315/2413/5413/5414 based) devices, leading to
messages such as:

ath5k phy0: gain calibration timeout (2462MHz)
ath5k phy0: calibration of channel 11 failed

When not SPROM is available a fallback mechanism is used. However,
when that fails the code currently continues. This patch assures
that the bcma_sprom_get() function aborts when that happens.

Subject: bcma: add support for on-chip OTP memory used for SPROM storage

Wireless Broadcom chips can have either their SPROM data stored
on either external SPROM or on-chip OTP memory. Both are accessed
through the same register space. This patch adds support for the
on-chip OTP memory.

Tested with:
BCM43224 OTP and SPROM
BCM4331 SPROM
BCM4313 OTP

This patch is in response to linux-wireless thread [1].

Cold reset is more reliable for getting the hardware out of some specific
stuck states.

Subject: ath9k: make MAC sample statistics optional

They're more expensive than some of the other debug options and only used
in very rare situations, so it sometimes makes sense to disable them while
leaving in debugfs support.

Subject: ath9k: remove rssi/antenna information from recv debug stats

The way this is implemented (simply storing the last value) is absolutely
worthless for debugging anything, and the same information is also available
through the MAC sample feature, so there's no point in keeping this around.

Subject: ath9k: fix signal strength reporting issues

On A-MPDU frames, the hardware only reports valid signal strength data for
the last subframe. The driver also mangled rx_stats->rs_rssi using the
ATH_EP_RND macro in a way that may make sense for ANI, but definitely
not for reporting to mac80211.
This patch changes the code to calculate the signal strength from the rssi
directly instead of taking the average value, and flag everything but
the last subframe in an A-MPDU to tell mac80211 to ignore the signal strength
entirely, fixing signal strength fluctuation issues reported by various
users.

Subject: iwlwifi: move ucode loading to op_mode

uCode loading belongs to the op_mode, as it
is dependent on various things there and the
commands sent during it are specific to it.
Move the prototypes to iwl-agn.h to indicate
this. To make this possible, also move all
the calibration handling (which is op_mode
dependent after all).

From 0692fe41b36159be5d8c7d4eef0699e79c383c85 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:37 -0800
Subject: iwlwifi: split out firmware store

Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.

From: Johannes Berg <johannes.berg@intel.com>

Subject: iwlwifi: remove iwl-wifi.h

This file was recently introduced, but then
directly abused -- it contained private data
that shouldn't have been used by anything
but the implementation of firmware requests
and some very core code. Now that it is no
longer accessed by any code but the code in
iwl-drv.c, we can dissolve it.

Also rename the iwl_nic struct to iwl_drv to
better reflect where and how it is used.

From e10a0533a9172471b52bd9512838d766420a3baf Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:39 -0800
Subject: iwlwifi: add wrappers for command sending

Add wrappers to send commands from the DVM
op-mode (which essentially consists of the
current driver). This will allow us to move
specific sanity checks there.

Also, this removes iwl_trans_send_cmd_pdu()
since that can now be taken care of in the
DVM-specific wrapper.

Subject: iwlwifi: move RF/CT kill check to command wrapper

Currently, we cannot send any commands when the
uCode is in RF or CT kill, but that will not be
true for all new uCode versions, so we need to
move the check into the uCode specific code.

Also remove the duplicate rfkill check.

Subject: iwlwifi: move lockdep assertion into DVM

The fact that the mutex must be held is an
implementation detail of DVM, but something
has to ensure that no two synchronous cmds
are submitted concurrently. Move the lockdep
assertion into the DVM-specific code, but
also make the transport abort if there are
two concurrently commands.

The assertion is much more useful though as
the transport check can only catch it when
it actually happens, while the assertion
makes sure it can't possibly happen.

From c9eec95cb429359efd39a3c87fb1544fe2b77bc5 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>

Subject: iwlwifi: move rfkill status handling out of transport

The transport layer should only check the
hardware RF kill status, not impose any
policy or reaction based on it, so move
that out of it into the op_mode.

For now keep the restriction on loading
firmware, that will have to be removed
later.

Subject: iwlwifi: rename ucode.h to fw-file.h

That name better reflects the contents
of the file and the fact that it isn't
related to iwl-ucode.c.

Subject: iwlwifi: remove AMT check from transport

As iwl_prepare_card_hw() is idempotent (and
many cards support AMT anyway) there's no
point in calling iwl_prepare_card_hw() only
for AMT capable devices -- call it always
and simplify the code that way.

Subject: iwlwifi: remove shadow_reg_enable from hw_params

There's no need to copy shadow_reg_enable into
hw_params since it is a pure hardware parameter
that will never change, we can access it from
the config directly.

Subject: iwlwifi: move status check functions out of shared

They are only used in the DVM op_mode.
Also move the rfkill debug macros that
depend on them.

Subject: iwlwifi: make tracing use device as identifier

Tracing used the priv pointer as an identifier,
which has the problem that we don't have it in
all code, and also some people say no pointers
should be "leaked" to userspace.

Use the device name instead, it is more useful
anyway.

Subject: iwlwifi: virtualize command queue full behaviour

When the command queue is full, the transport
will return -ENOSPC, but the reaction to that
depends on the op_mode. Virtualize that, the
DVM op_mode checks for CT-kill and restarts
the hardware otherwise.

We may be able to get rid of this callback by
putting the behaviour check into the wrapper
but that needs more careful evaluation.

Subject: iwlwifi: fix notification wait bug

In "iwlwifi: consolidate the start_device flow"
Emmanuel added the return if the fw isn't there
but forgot to take into account that the struct
for notification wait needs to be added only
after the check -- fix that.

Subject: iwlwifi: abstract out notification wait support

This will be sharable, but needs to live in the
op_mode as it is dependent on command processing.
Make a library out of the notification wait code.

Since I wrote all of the code originally and only
Intel employees changed it, we can also relicense
it to dual BSD/GPL.

Subject: iwlwifi: move ucode_owner to priv

The transport doesn't really need to know as
we can enforce it in the command wrapper.
Move the ucode_owner variable into priv and
do all enforcing there.

Subject: iwlwifi: move irq to PCIe

Even if the variable might also be used by other
transports, there's no need for anything outside
of the transport itself to access it, so move it
into the private area.

Subject: iwlwifi: move packet to transport

The base packet structure will (hopefully) be
the same for all transports, but what is in it
differs. Remove the union of all the possible
contents and move the packet itself into the
transport header file. This requires changing
all users of the union to just use pkt->data.

for the PA type, we can just use the
additional NIC config function to config
the hardware correctly.

From 55df5afb13718cda49128fa5985556df91d07765 Mon Sep 17 00:00:00 2001
From: Arik Nemtsov <arik@wizery.com>

Subject: wl12xx: implement SW Tx watchdog

Track freed FW blocks during Tx. If no blocks were freed during a
predefined timeout, initiate a HW recovery. This helps in situations
when the FW watchdog fails.

Don't trigger recovery during activities that can temporarily stop
Tx. This includes:
- scanning
- buffering packets for sleeping stations (AP role)
- ROC on any role

Subject: iwlwifi: redesign PASSIVE_NO_RX workaround

The PASSIVE_NO_RX workaround currently crosses
through the op_mode and transport layers, which
is a bit odd. This also isn't necessary, if the
transport simply reports when queues are full
(or no longer full) the op_mode can keep track
of this state, and report to mac80211 only what
*it* thinks is appropriate. What is appropriate
can then be based on whether queues should be
stopped to wait for RX or not.

This significantly simplifies the transport API,
it no longer needs to expose anything to stop a
queue, nor to wake "any" queue, this can all be
handled in the upper layer completely.

Also simplify the handling to not be dependent
on the context, that makes little sense as the
queues are shared and both contexts have to be
on the same channel anyway.

At least as long as it is called from the reclaim
flow (iwlagn_check_ratid_empty) it must be atomic.

Subject: iwlwifi: remove BT handlers from lib_ops

There's no need to have operations for
these as they simply depend on whether
the device has built-in bluetooth, so
just duplicate the information already
there (whether bt_params is present or
not).

Subject: iwlwifi: dump stack when fail to gain access to the device

Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

Before we write to the device registers always check if
iwl_grap_nic_access() was successful.

On the way change return type of grab_nic_access() to bool, and add

Subject: iwlwifi: cleanup/fix memory barriers

wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlwifi devices are most likely
not used on anything other than x86, this is not so important
fix.

If device is disabled by rfkill switch, do not enable all interrupts,
but only CSR_INT_BIT_RF_KILL to receive rfkill state change. Unblocking
other interrupts might cause problems, since driver can not be prepared
for receive them.

Subject: iwlwifi: add testmode command for rx forwarding

Added a testmode command which tells iwl_rx_dispatch
to send the RX both as a notification to nl80211 and
with the registered RX handlers.

This is used for monitoring RX from userspace while preserving
the regular flows in the driver.

full (or non-full), so the messages aren't
useful any more -- remove them.

Subject: iwlwifi: don't delete AP station directly

With the mac80211 deauth sequence changes, the
station is deleted before the device is set
unassociated. This can cause the device to get
confused as it expects the station to be there
while the associated bit is set.

To fix this, do not delete the AP station from
the device when mac80211 asks for deletion,
instead just mark it as unused and rely on the
unassociated RXON to drop it from the station
database in the device.

Subject: mwifiex: correction in number of bitrates

In recent commit "mwifiex: correct bitrates advertised..", we have
removed 22Mbps and 72Mbps bitrates from supported bitrate array.
It means number of bitrates has reduced from 14 to 12.

Initialize ".n_bitrates" to array size instead of hardcoding it.

The command queue number is required by the transport
layer, but it can be determined only by the op mode.
Move this parameter to the dvm op mode, and configure
the transport layer using an API.

Subject: iwlwifi: restore PAN support

in iwlwifi: move setting up fw parameters

Meenakshi moved code up to configure the transport layer, but this
code read the sku before it was set (from the EEPROM). This killed
P2P.
Only the ucode_flags are needed to configure the transport layer, not
the sku which _must_ be set after the EEPROM is read.

We need to reconfigure the transport in case the EEPROM disabled PAN
support. This is not the nicest thing to do, but we have no choice.
Document that we are allowed to configure the transport several times
before start_fw, but not after.
