Eliad Peller 7f97b487c4 wl12xx: use ap_bcast_hlid for recorded keys
when the key was recorded, wl->ap_bcast_hlid was invalid
(since the role wasn't started), so when configuring the
key we need to use the current ap_bcast_hlid.

Arik Nemtsov 1a8adb67f9 wl12xx: AP-mode - configure HT rate support to the FW
Unconditionally configure HT rate support to the FW on all ACs
when starting the AP.

When 11n support is disabled by usermode (hostapd), each STA joining
the AP will appear as a non-HT STA. This will stop us from accidentally
transmitting using MCS rates.

Eliad Peller 251c177f88 wl12xx: replace dummy_join with ROC/CROC commands
The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:

1. Allow tx/rx from the device role.

In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.

Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.

2. Keeping the antenna for a specific link.

We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).

During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.

Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.

Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.

The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control
the ROC during connection.

Marek Lindner f3d4505de5 ath9k: remove eeprom txgain override for minor version < 19
ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the
minor version is not 19 or above with a value of 0.
ar9002_hw_init_mode_gain_regs() relies on this information to
determine whether this is a high power wifi card or not. The override
caused the driver to always use the 'normal' power tables even for
high power devices if their minor version was not high enough. Thus
leading to reduced power output.

This isn't needed for the AR9285; the check originated with the
AR9280 setup code which requires the EEPROM version check.

Helmut Schaa abc1199411 rt2x00: Fix PCI interrupt processing race on SMP systems
When toggle_irq is called for PCI devices to disable device interrupts
it used tasklet_disable to wait for a possibly running tasklet to finish.
However, on SMP systems the tasklet might still be scheduled on another CPU.
Instead, use tasklet_kill to ensure that all scheduled tasklets are finished
before returning from toggle_irq.

Furthermore, it was possible that a tasklet reenabled its interrupt even
though interrupts have been disabled already. Fix this by checking the
DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts
during tasklet processing.

While at it also enable/kill the TBTT and PRETBTT tasklets in the
toggle_irq callback and only use tasklet_kill in stop_queue to wait
for a currently scheduled beacon update before returning.

Rajkumar Manoharan e8fe733684 ath9k: Use atomic reference count for interrupt ops
Let us enable/disable interrupts based on reference count.
By doing this we can ensure that interrupts are never be
enabled in the middle of tasklet processing. Instead of
addressing corner cases like "ath9k: avoid enabling interrupts
while processing rx", this approach handles it in generic manner.

Rajkumar Manoharan b037b69326 ath9k: do not enable interrupt on set interrupt mask
At preset set_interrupt also enables interrupt after changing
mask. This is not necessary in all cases and also sometime it
breaks the assumption that interrupt was disabled. So let us
enable the interrupt explicity if it was disabled earlier.
This could also avoid unnecessary register ops and also helps
the follow up patch to have global ref count for interrupts ops.

Daniel Drake d2e7b3425c libertas: disable functionality when interface is down
Modify the driver so that it does not function when the interface is
down, in preparation for runtime power management.

No commands can be run while the interface is down, so the ndo_dev_stop
routine now directly does all necessary work (including asking the device
to disconnect from the network and disabling multicast functionality)
directly.

power_save and power_restore hooks are added meaning that card drivers
can take steps to turn the device off when the interface is down.

The MAC address can now only be changed when all interfaces are down;
the new address will be programmed when an interface gets brought up.
This matches mac80211 behaviour.

Also, some small cleanups/simplifications were made in the surrounding
device handling logic.

Raja Mani 9aa603578f ath6kl: Fix crash during the connection process
Sometimes, the network manager is failing to connect to the AP due
to the below kernel crash message. The reason behind this,
after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.

The host driver resets all states (including cfg80211 state machine)
when it receives disconnect event from the chip. But, still the host
driver reports the next received connect event to cfg80211, at that time
cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.

Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211

When ath6kl module was removed while a scan was ongoing the driver would

Fix the function not to iterate nodes when the scan is aborted. The nodes
are already freed when the module is being unloaded. This patch removes the
null check entirely as the wmi structure is not accessed anymore during
module unload.

Also fix a bug where the status was checked as a bitfield with '&' operator.

when connected to makes the problem go away. This is more like
a workaround than a proper fix, but as the stall is so severe the
workaround is justified.

With a dual band card this increases scan time when connected from
1.9s to 4.4s. When not connected the scan time is not affected and
is the same 1.9s.

Kalle Valo bdcd817079 Add ath6kl cleaned up driver
Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:

http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary

After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.

The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)

There are two remaining checkpatch warnings in the driver which we
decided to omit for now:

drivers/net/wireless/ath/ath6kl/debug.c:31:
  WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
  WARNING: msleep < 20ms can sleep for up to 20ms;
  see Documentation/timers/timers-howto.txt

The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.

We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.

Notable missing features compared to the current staging driver are:

o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support

Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.

Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.

Various people have been working on the cleanup, the hall of
fame based on number of patches is:

Felix Fietkau f23fba49b3 ath9k_hw: calculate a much better approximation of channel noise
Currently ath9k presents the internal calibrated noise floor as channel
noise measurement, however this results in highly chip specific values
that are only useful as relative measurements but do not resemble any
real channel noise values.

In order to give a much better approximation of the real channel noise,
add the difference between the measured noise floor and the nominal
chip specific noise floor to the default minimum channel noise value,
which is currently used to calculate the signal strength from the RSSI
value. This may not be 100% accurate, but it's much better than what's
there before.

Johannes Berg 5d7969bf2b iwlagn: separate firmware version warning
We sometimes need to support new firmware API for
a while before we can publish them since testing
them fully takes a long time. We could keep all
the new code private, but that causes plenty of
problems and sometimes we can give a pre-release
version of firmware to people who need to test.
However, when we just bump the API version, the
driver will warn everybody that their firmware is
outdated, when in fact it isn't. (Currently our
case for this doesn't really change the API but
bumping the API version is necessary because the
firmware isn't fully backward compatible)

In order to handle this in the future, add a new
"api_ok" version; only below this will the driver
warn that the uCode is too old.

New uCode images will use queue 10 for TX

but before we need to reserve queue 10 and
stop using it for aggregation.

To simplify the code, always reserve it,
we could continue using it on older uCode
images but that'd be rather complicated.
Also, we'll set it up to map to the right
FIFO as needed later, but as we don't use

Larry Finger b6b67df3f2 rtlwifi: Fix kernel oops on ARM SOC
This driver uses information from the self member of the pci_bus struct to
get information regarding the bridge to which the PCIe device is attached.
Unfortunately, this member is not established on all architectures, which
leads to a kernel oops.

Skipping the entire block that uses the self member to determine the bridge
vendor will only affect RTL8192DE devices as that driver sets the ASPM support
flag differently when the bridge vendor is Intel. If the self member is
available, there is no functional change.

This patch fixes Bugzilla No. 40212.

We receive many bug reports about system hang during suspend/resume

To do not hit the bug, skip doing ->config_pci_powersave magic if PCIe

disabled.

Bug was introduced by:

https://bugzilla.redhat.com/show_bug.cgi?id=697157

however I did not receive confirmation about that, except from Camilo
Mesias, whose system stops hang regularly with this patch (but still

I noticed that you took some time back in late 2009 to 'consolidate' the
split format-strings present in the bonding driver at the time and I've
decided I'm fine to leave them the way they are.  The main point of my
patch was to change the output and I would like to get that included.
Here is my updated patch...

Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init

Many are using sysfs to configure bonding rather than module options, so
there is no need for bonding to throw this warning in normal cases.

Keep the message around when debugging is enabled as it might be useful
for someone desperate enough to enable debugging, but eliminate it
otherwise.

Andy Gospodarek f4bb2e9c4f bonding: fix string comparison errors
When a bond contains a device where one name is the subset of another
(eth1 and eth10, for example), one cannot properly set the primary
device or the currently active device.

This was reported and based on work by Takuma Umeya.  I also verified
the problem and tested that this fix resolves it.

V2: A few did not like the the current code or my changes, so I
refactored bonding_store_primary and bonding_store_active_slave to be a
bit cleaner, dropped the use of strnicmp since we did not really need
the comparison to be case insensitive, and formatted the input string
from sysfs so a comparison to IFNAMSIZ could be used.

I also discovered an error in bonding_store_active_slave that would
modify bond->primary_slave rather than bond->curr_active_slave before
forcing the bonding driver to choose a new active slave.

V3: Actually sending the proper patch....

them as not being able to support the safe transmission of skbs by clearning the

   When these mailbox commands are processed by the FW and responses are sent,
   unexpected  events are received by other modules' FSMs (f.e. bfa_msgq) which
   have not posted any mailbox commands after IOC was enabled.
 - Flush the pending mailbox command queue when IOC is disabled. Rename

Andy Gospodarek 9417c464ba ixgbe: only enable WoL for magic packet by default
Martin Wilck <martin.wilck@ts.fujitsu.com> reported that systems using
the ixgbe-driver that were capable of WoL were rebooting almost as soon
as they were shut down.  This is because the default WoL settings
enabled magic packet, broadcast, unicast, and multicast.

Other Intel devices seem to use the stored eeprom value for initial WoL
capabilities.  The 82578DM (e1000e) and 82576 (igb) the devices I looked
at had only the magic packet enabled in the eeprom, so that seems
appropriate on ixgbe-based devices as well.  I set the WoL options on my
82578DM to be the same default as the ixgbe devices (umbg) and saw the
same as Martin -- almost as soon as my box shutdown, it booted again.

This patch changes the default to only be the magic packet.  This is the
same as the default for most Intel and non-Intel hardware currently
upstream.

Alexander Duyck bd19805803 ixgbe: Move interrupt related values out of ring and into q_vector
This change moves work_limit, total_packets, and total_bytes into the ring
container struct of the q_vector.  The advantage of this is that it should
reduce the size of memory used in the event of multiple rings being
assigned to a single q_vector.  In addition it should help to reduce the
total workload for calculating itr since now total_packets and total_bytes
will be the total work done of the interrupt instead of for the ring.

Sathya Perla 2dc1deb659 be2net: request native mode each time the card is reset
Currently be3-native mode is requested only in probe(). It must be requested, each time the card is reset either after an EEH error or after
sleep/hibernation.
Also, the be_cmd_check_native_mode() is better named be_cmd_req_native_mode()

Krishna Kumar 2e66f55b3a virtio_net: Fix panic in virtnet_remove
Fix a panic in virtnet_remove. unregister_netdev has already
freed up the netdev (and virtnet_info) due to dev->destructor
being set, while virtnet_info is still required. Remove
virtnet_free altogether, and move the freeing of the per-cpu
statistics from virtnet_free to virtnet_remove.

Tested patch below.

Shreyas Bhatewara e101e7ddad vmxnet3: set netdev parant device before calling netdev_info
Parent device for netdev should be set before netdev_info() can be called
otherwise there is a NULL pointer dereference and probe() fails.

Giuseppe CAVALLARO 36bcfe7d74 stmmac: unify MAC and PHY configuration parameters (V2)
Prior to this change, most PHY configuration parameters were passed
into the STMMAC device as a separate PHY device. As well as being
unusual, this made it difficult to make changes to the MAC/PHY
relationship.

This patch moves all the PHY parameters into the MAC configuration
structure, mainly as a separate structure. This allows us to completely
ignore the MDIO bus attached to a stmmac if desired, and not create
the PHY bus. It also allows the stmmac driver to use a different PHY
from the one it is connected to, for example a fixed PHY or bit banging
PHY.

Also derive the stmmac/PHY connection type (MII/RMII etc) from the
mode can be passed into <platf>_configure_ethernet.
STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git
provides several examples how to use this new infrastructure (that
actually is easier to maintain and clearer).

Guo-Fu Tseng 94c5b41b32 jme: Fix unmap error (Causing system freeze)
This patch add the missing dma_unmap().
Which solved the critical issue of system freeze on heavy load.

Michal Miroslaw's rejected patch:
[PATCH v2 10/46] net: jme: convert to generic DMA API
Pointed out the issue also, thank you Michal.
But the fix was incorrect. It would unmap needed address
when low memory.

Got lots of feedback from End user and Gentoo Bugzilla.
https://bugs.gentoo.org/show_bug.cgi?id=373109
Thank you all. :)
