For AP mode we must tune ANI specially for 2 GHz and
for 5 GHz. We mask in only the flags we want to toggle
on ath9k_hw_ani_control() through the ah->ani_function
bitmask, this will take care of ignoring changes during
ANI reset which we were disabling before.

Pavel Roskin reported some issues with using AP mode without
nohwcrypt=1. Most likely this is similar to the problem fixed
some time ago in ath9k by 3f53dd64f1,
"ath9k: Fix hw crypto configuration for TKIP in AP mode."
That only affects TKIP but it's easiest to just disable that and
WEP too until we get a proper fix in.

requested as it will be the number just written to this file. It

In addition it fixes a problem where powertop's parsing expects

The tx ring accounting fix in commit cb2107be43
("netxen: fix tx ring accounting") introduced intermittent

This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean

The connector documentation states that the argument to the callback
function is always a pointer to a struct cn_msg, but rather than encode it
in the API itself, it uses a void pointer everywhere. This doesn't make
much sense to encode the pointer in documentation as it prevents proper C
type checking from occurring and can easily allow people to use the wrong
pointer type. So convert the argument type to an explicit struct cn_msg
pointer.

Bonding device forbids slave device of different types under the same
master.
However, it is possible for a bonding master to change type during its
lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND
or the other way arround. The change of type requires device level
multicast address cleanup because device level multicast addresses
depend on the device type.
The patch adds a call to dev_close() before the bonding master changes
type and dev_open() just after that.
In the example below I enslaved an IPoIB device (ib0) under
bond0. Since each bonding master starts as device of type ARPHRD_ETHER
by default, a change of type occurs when ib0 is enslaved.
This is how /proc/net/dev_mcast looks like without the patch
5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05
5 bond0 1 0 01005e000116

6 ib0 1 0 00ffffffff12601bffff00000000000000000001
and this is how it looks like after the patch.

The issue was, that the locking code in mkiss was assuming it was only
ever being called in process or bh context. Fixed by converting the
involved locking code to use irq-safe locks.
Review of other networking line disciplines shows that 6pack, both sync
and async PPP and STRIP have similar issues. The ppp_async one is the
most interesting one as it sorts out half of the issue as far back as
2004 in commit http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=2996d8deaeddd01820691a872550dc0cfba0c37d

Using the enable_beacon flag allows some simplifications and fixes
some corner cases in beacon handling. This change adds a state
variable for beaconing in ath5k_beacon_config and handles both
enabling and disabling, thus eliminating the need for
ath5k_beacon_disable. We also now configure the beacon when any
of the beacon parameters change, so ath5k_beacon_reconfig is no
longer needed (its mmiowb gets moved to ath5k_beacon_config).
Finally, by locking around the whole config function, we don't
need to worry about clearing the interrupt mask register before
installing the new mask.
The upshot is this correctly disables beaconing when the interfaces
are taken down, it fixes a potential restarting of beaconing
when ath5k_reset() is called, and ensures that updates to the
beacon interval take effect immediately.

We were not differentiating quality between legacy and HT
configurations. We change this to consider the differences.
New theory for reporting quality:
At a hardware RSSI of 45 you will be able to use MCS 7 reliably.
At a hardware RSSI of 45 you will be able to use MCS 15 reliably.
At a hardware RSSI of 35 you should be able use 54 Mbps reliably.
MCS 7 is the highets MCS index usable by a 1-stream device.
MCS 15 is the highest MCS index usable by a 2-stream device.
All ath9k devices are either 1-stream or 2-stream.
How many bars you see is derived from the qual reporting.
A more elaborate scheme can be used here but it requires tables
of SNR/throughput for each possible mode used. For the MCS table
you can refer to the wireless wiki:
http://wireless.kernel.org/en/developers/Documentation/ieee80211/802.11n

The SDIO driver sets the surpriseremoved flag before calling
lbs_remove_card. With IEEE PS enabled, lbs_remove_card must issue a
command to exit IEEE PS mode, however with that flag set the command
path is blocked and the card is never taken out of IEEE PS mode. This
step is required to ensure that the driver can be reloaded. This patch
moves the setting of surpriseremoved after lbs_remove_card is called.
Tested with V9 firmware by ensuring that IEEE PS is disabled when the
driver is removed. Reloading the driver is not fully tested due to a
separate issue with module reload in the SDIO driver, however this
patch at least leaves the card in a better state when we bring the
driver down.

The SPI driver does a couple of card cleanup steps in the wrong order on
module removal. If IEEE PS is enabled, this results in the card being
left in IEEE PS mode and subsequent failures to reload the module. The
problem is that the surpriseremoved flag is set before calling
lbs_remove_card, but that function needs to issue a command to exit IEEE
PS mode (the flag blocks the command path). In addition, lbs_stop_card
should be called first because it clears out any pending commands.
Tested on a GSPI device with V9 firmware by confirming that we can
reload the module with or without IEEE PS enabled.
Also fix a warning from the wrong uint format in a printk.

Libertas currently maintains a copy of the WPA unicast and group keys
when using WPA or WPA2. This copy is checked when deciding whether or
not to return to sleep in IEEE PS mode but the actual copying back to
priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one
issues commands that require temporarily keeping the device awake.
This patch introduces the omitted copy-back of the keys so that IEEE PS
functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for
clearing up the issue.

This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.
The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).
I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.
Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.
