6fb532527e libertas: Create sysfs entry for changing the mesh probe response limit
This patch adds the ability to change the number of probe response retries sent
by the mesh interface.

In dense networks it is recommended to change this value to zero to reduce
traffic congestion.

b7a530d82c mac80211: Disable requests for new scans in AP mode
AP mode operations are seriously affected if mac80211 runs through a
multi-second scan while the AP is trying to send Beacon frames on the
operation channel. While this could be implemented in a way that does
not cause too many problems, it is not very simple and will require
synchronization with Beacon frame scheduling in the drivers (scan one
channel at a time between Beacon frames). Furthermore, such scanning
takes quite a bit longer time and existing userspace applications
would be likely to timeout while waiting for the results.

For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP
mode. In practice, this moves the rejection from iwl* drivers into
mac80211 to make it apply to every mac80211-based driver.

This issue shows up in associated stations getting disconnected when
something (e.g., Network Manager) requests a scan while the interface
is in AP mode. When doing this continuously (e.g., NM does it every 120
seconds), the network gets close to useless.

14a4dfe2ff ipw2200: fix scanning while associated
This patch fixes sporadic firmware restarts when scanning while associated.

The firmware will quietly cancel a scan (while associated) if the dwell time
for a channel to be scanned is larger than the time it may stay away from the
operating channel (because of DTIM catching). Unfortunately the driver is not
notified about the canceled scan and therefore the scan watchdog timeout will
be hit and the driver causes a firmware restart which results in
disassociation. This mainly happens on passive channels which use a dwell time
of 120 whereas a typical beacon interval is around 100.

The patch changes the dwell time for passive channels to be slightly smaller
than the actual beacon interval to work around the firmware issue. Furthermore
the number of allowed beacon misses is increased from one to three as otherwise
most scans (while associated) won't complete successfully.

However scanning while associated will still fail in corner cases such as a
beacon intervals below 30.

c1db52b9d2 rtl8187: Use usb anchor facilities to manage urbs
When SLUB debugging is enabled in the kernel, and the boot command includes
the option "slub_debug=P", rtl8187 encounters a GPF due to a read-after-free
of a urb.

Following the example of changes in p54usb to fix the same problem, the code
has been modified to use the usb_anchor_urb() method. With this change, the
USB core handles the freeing of urb's.

This patch fixes the problem reported in Kernel Bugzilla #12185
(http://bugzilla.kernel.org/show_bug.cgi?id=12185).

dd397dc9dd p54usb: rewriting rx/tx routines to make use of usb_anchor's facilities
Alan Stern found several flaws in p54usb's implementation and annotated:
"usb_kill_urb() and similar routines do not expect an URB's completion
routine to deallocate it.  This is almost obvious -- if the URB is deallocated
before the completion routine returns then there's no way for usb_kill_urb
to detect when the URB actually is complete."

This patch addresses all known limitations in the old implementation and fixes
khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

a07d3619fa ath9k: BH shouldn't be enabled when hardirqs are disabled.
ath_tx_complete_buf uses a BH version of spinlock and so releasing
the lock enables BH which is incorrect when called from sta_notify
callback as MAC80211 disables hardirqs before the driver callback
is called.

As ath_tx_complete_buf is shared between user and softirq context
using normal spinlock may not be appropriate. Though the proper
fix would be to cleanup the context properly in the driver code,
this would be an interim fix to avoid kernel warning.

6b3aa6ab78 ath9k: Disable staggered Beacon frame scheduling
It looks like there are some issues in the current ath9k version as
far as staggered Beacon frame scheduling is concerned. This results in
Beacon frame timestamp being off by 25 milliseconds or so which can
cause issues with multicast power save buffering in AP mode. Some
client stations fail to receive multicast frames when there is this
large an offset between TBTT and actual Beacon transmission time.

Since ath9k does not yet support multiple BSSes anyway, the staggered
Beacon frame scheduling is just increasing the number of interrupts at
this point. The easiest fix for the timestamp offset is to disable
staggered Beacon frames for now. We need to redesign beacon.c anyway
when adding multi-BSS support with mac80211 since the existing code
depends on different mechanism for Beacon frame transmission.

The old version of this code was copied from 3945 and never updated. This patch
cleans up structs that do not apply and accounts for other changes from
3945->iwlagn (e.g., PHY info can come in a separate cmd response from the
ucode.)

447107fb32 mac80211: remove WARN_ON() from ieee80211_hw_config
ieee80211_hw_config can return an error when the hardware
has rfkill enabled. A WARN_ON() is too harsh for this
failure as it is a valid scenario. Only comment this warning
as we would like to have it back when rfkill is integrated into
mac80211.

Also reintroduce propagation of error if ieee80211_hw_config fails
in ieee80211_config_beacon.

This patch partially reverts patch:

bb608e9db7 wireless: Incorrect LEAP authentication algorithm identifier.
This patch fixes a regression introduced by
"wireless: avoid some net/ieee80211.h vs. linux/ieee80211.h conflicts"
LEAP authentication algorithm identifier should be 128.

a7db74f4be rtl8187: Improve wireless statistics for RTL8187
The current wireless statistics for the RTL8187 poorly indicate the signal
strength and quality. With testing, I found that the AGC value is inversely
correlated with the strength as in the RTL8187B. By implementing a similar
calculation, much more code becomes common to the two devices.
