While switching b/w HT20/40, the current channel's nf values
are updated into history buffer. Since the current channel's
channel type, channel flag got updated before reading
nf value from hw. This channel type mismatch is causing invalid
readings when hw is on ht20 but getnf tries to read on extn chains.

Before doing hw reset the current channel's noisefloor readings
are updated into history buffer. The extension chain's readings
are considered only if the current channel was configured in HT40.
While moving from HT40 to HT20, the extn chain's readings are
skipped though the current channel is in ht40. This patch updates
extn chain reading based on channel flag.

When a client disassociates from a crypto enabled bss, data traffic to
other clients connected to the bss is stalled. This was due to a boolean
variable used to keep track if HW crypto is enabled i.e. if set key has
been called to add a key. This flag was being reset every time delete
key was called e.g when a station leaves the bss. Once the flag is
reset, rx status flags were not being set for connected clients which
disrupts traffic to these clients. Fix this issue by not resetting the
flag since we do not need to reset this flag during the life time of the

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

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

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.

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.

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

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

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:

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.

a while before we can publish them since testing
them fully takes a long time. We could keep all

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)

The driver reads PCI subsystem ID from the PCI configuration register while it's
already stored by the PCI subsystem in the 'subsystem_device' field of 'struct
pci_dev'...

Currently, "udevadm info -a -p /sys/class/net/wlan0" doesn't mention
the usb8xxx or libertas driver anywhere. This makes writing udev rules
a bit uncomfortable.
Using the USB interface as the parent device corrects the hierarchy.

The mesh device is now exposed as an interface of the wiphy.
This exposes the mesh device to the cfg80211 interface, allowing
mesh channel selection to be reimplemented, and available to
NetworkManager as it was before.
Some header tweaking was needed in order to implement lbs_mesh_activated().

In trying to remove the wext includes from mac80211
and cfg80211 I found that mwifiex currently uses
them. This is wrong, it shouldn't, but to not break
it completely include wext there.
Please remove this and fix all the resulting bugs.

This driver uses IW_ESSID_MAX_SIZE when it should
be using IEEE80211_MAX_SSID_LEN instead.
