The commit below changed the semantics of rt2x00_check_rev so that it no
longer checked the bottom 4 bits of the rev were non-zero. During that
conversion this part of the check was not propogated to the rt2500usb
initialisation.

rt2x00: Simplify rt2x00_check_rev
Without this check rt73 devices are miss recognised as rt2500 devices and
two drivers are loaded. Preventing the device being used. Reinstate this
check.

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.

This changes the power_level file to adhere to the "one value
per file" sysfs rule. The user will know which power level was
requested as it will be the number just written to this file. It
is thus not necessary to create a new sysfs file for this value.
In addition it fixes a problem where powertop's parsing expects
this value to be the first value in this file without any descriptions.

The issue was, that the locking code in mkiss was assuming it was only

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.

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.

Initialise and register a wiphy.
Store the orinoco_private structure in the new wiphy, and use the
net_device private area to store the wireless_dev. This results in a
change to the way we navigate from a net_device to the driver private
orinoco_private, which we encapsulate in the inline function ndev_priv.
Most of the remaining calls to netdev_priv are thus replaced by
ndev_priv.
We can immediately rely on cfg80211 to handle SIOCGIWNAME, so
orinoco_ioctl_getname is removed.

In the mainline kernel, p54usb will fail because the TX queue length can
become < 0. This problem has been reported as Bugzilla #13725. The failure
is expressed by the following message in the logs:

Atheros top level menu needs a "depends WLAN_80211" to properly indent
within menuconfig and xconfig interfaces.
This is purely a visual issue but it effects all subsequent drivers.
The issue is the top level menu does not include a dependency on
WLAN_80211 so within the tree structure, Atheros is at the same level as
WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with
all subsequent drives, so it is really a subordinate.

When we reclaim the tx desc, we always assume that the
last desc is a holding desc, which is not true, and skip it.
If the tx queue is drained during channel change, internal
reset and etc, the last descriptor may not be the holding
descriptor and we fail to reclaim them. This results in the
following two issues.
1. Tx stuck - We drop all the frames coming from upper layer
due to shortage in tx desc.
2. Crash - If we fail to reclaim a tx descriptor, we miss to
update the tx BA window with the seq number of the frame
associated to that desc, which, at some point, result in
the following crash due to an assert failure in ath_tx_addto_baw().
This patch fixes these two issues.

An earlier commit, 'ath9k: remove dummy PCI "retry timeout" fix', removed
code that was documented to disable RETRY_TIMEOUT register (PCI reg
0x41) since it was claimed to be a no-op. However, it turns out that
there are some combinations of hosts and ath9k-supported cards for
which this is not a no-op (reg 0x41 has value 0x80, not 0) and this
code (or something similar) is needed. In such cases, the driver may
be next to unusable due to very frequent PCI FATAL interrupts from the
card.
Reverting the earlier commit, i.e., restoring the RETRY_TIMEOUT
disabling, seems to resolve the issue. Since the removal of this code
was not based on any known issue and was purely a cleanup change, the
safest option here is to just revert that commit. Should there be
desire to clean this up in the future, the change will need to be
tested with a more complete coverage of cards and host systems.

AGGR_ADDBA_PROGRESS should be cleared in aggr state when addba
negotiation is terminated due to either addba response is timed out
or addba is denied by the AP. With out clearing this bit,
all frames are queued onto s/w queue for getting tx'd as aggr and

This patch introduces initial rfkill support for the ath5k driver
based on rfkill support in the cfg80211 framework.
All rfkill related code is separated into newly created rfkill.c.
Changes to existing code are minimal:
* added a new data structure ath5k_rfkill to the ath5k_softc structure
* inserted calls to HW rfkill init/deinit routines
* ath5k_intr() has been extended to handle AR5K_INT_GPIO interrupts

This patch is a back-port from aggregation testing code.
In the past, we didn't limit the amount of active tx urbs.
However, ar9170 only has a limited buffer reserved for
pending data frames.
This wasn't much of a problem with the slower 802.11b/g.
We simply stopped the full queue and moved on to something different
in the mean time. But - as you guessed it - this simple approach
stands in way for a decent aggregation implementation.

Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903
when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.
Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.
In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.

This patch completely rewrites the rfkill core to address
the following deficiencies:
* all rfkill drivers need to implement polling where necessary
rather than having one central implementation
* updating the rfkill state cannot be done from arbitrary
contexts, forcing drivers to use schedule_work and requiring
lots of code
* rfkill drivers need to keep track of soft/hard blocked
internally -- the core should do this
* the rfkill API has many unexpected quirks, for example being
asymmetric wrt. alloc/free and register/unregister
* rfkill can call back into a driver from within a function the
driver called -- this is prone to deadlocks and generally
should be avoided
* rfkill-input pointlessly is a separate module
* drivers need to #ifdef rfkill functions (unless they want to
depend on or select RFKILL) -- rfkill should provide inlines
that do nothing if it isn't compiled in
* the rfkill structure is not opaque -- drivers need to initialise
it correctly (lots of sanity checking code required) -- instead
force drivers to pass the right variables to rfkill_alloc()
* the documentation is hard to read because it always assumes the
reader is completely clueless and contains way TOO MANY CAPS
* the rfkill code needlessly uses a lot of locks and atomic
operations in locked sections
* fix LED trigger to actually change the LED when the radio state
changes -- this wasn't done before

directly to send function init/shutdown command for SD8688 in
if_sdio_probe() or if_sdio_remove() callback.
2. add global variable "user_rmmod" to distinguish between the module
removal case and the card removal case. This flag will be checked in
if_sdio_remove() against SD8688 card to determine whether or not the
function shutdown command needs to be sent.
3. remove "card" from if_sdio_model structure as it cannot store
card pointers for multiple cards. Besides, it's no longer needed

It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

us waking up way too early to receive a Beacon frame. In order to work

The previous version used a simple loop to go through all Beacon
frames when determining the next TBTT and DTIM count. This is not too
bad for the case where the setup happens before timesync (i.e., very
small TSF), but this can become very heavy operation if a short Beacon
interval is used and the current TSF is large.
In preparation for a patch to update timer setup based on Beacon
timestamp, optimize this routine to take fixed time regardless of the
actual TSF value.

The previous implementation was moving back to NETWORK SLEEP state
immediately after receiving a Beacon frame. This means that we are
unlikely to receive all the buffered broadcast/multicast frames that
would be sent after DTIM Beacon frames. Fix this by parsing the Beacon
frame and remaining awake, if needed, to receive the buffered
broadcast/multicast frames. The last buffered frame will trigger the
move back into NETWORK SLEEP state.
If the last broadcast/multicast frame is not received properly (or if
the AP fails to send it), the next Beacon frame will work as a backup
trigger for returning into NETWORK SLEEP.
A new debug type, PS (debug=0x800 module parameter), is added to make
it easier to debug potential power save issues in the
future. Currently, this is only used for the Beacon frame and buffered
broadcast/multicast receiving.

We are not correctly listening to the regulatory max bandwidth
settings. To actually make use of it we need to redesign things
a bit. This patch does the work for that. We do this to so we
can obey to regulatory rules accordingly for use of HT40.
We end up dealing with HT40 by having two passes for each channel.
The first check will see if a 20 MHz channel fits into the channel's
center freq on a given frequency range. We check for a 20 MHz
banwidth channel as that is the maximum an individual channel
will use, at least for now. The first pass will go ahead and
check if the regulatory rule for that given center of frequency
allows 40 MHz bandwidths and we use this to determine whether
or not the channel supports HT40 or not. So to support HT40 you'll
need at a regulatory rule that allows you to use 40 MHz channels
but you're channel must also be enabled and support 20 MHz by itself.
The second pass is done after we do the regulatory checks over
an device's supported channel list. On each channel we'll check
if the control channel and the extension both:
o exist
o are enabled
o regulatory allows 40 MHz bandwidth on its frequency range
This work allows allows us to idependently check for HT40- and
HT40+.

Calling cancel_delayed_work() from inside
spin_lock_irqsave, introduces a potential deadlock.
As explained by Johannes Berg <johannes@sipsolutions.net>
A - lock
T - timer
phase CPU 1 CPU 2
---------------------------------------------
some place that calls
cancel_timer_sync()
(which is the | code)
lock-irq(A)
| "lock-irq"(T)
| "unlock"(T)
| wait(T)
unlock(A)
timer softirq
"lock"(T)
run(T)
"unlock"(T)
irq handler
lock(A)
unlock(A)
Now all that again, interleaved, leading to deadlock:
lock-irq(A)
"lock"(T)
run(T)
IRQ during or maybe
before run(T) --> lock(A)
"lock-irq"(T)
wait(T)
We fix this by moving the call to cancel_delayed_work() into workqueue.
There are cases where the work may not actually be queued or running
at the time we are trying to cancel it, but cancel_delayed_work() is
able to deal with this.
Also cleanup iwl_set_mode related to this call. This function
(iwl_set_mode) is only called when bringing interface up and there will
thus not be any scanning done. No need to try to cancel scanning.

reported at http://marc.info/?l=linux-wireless&m=124081921903223&w=2 .

Commit e8f055f0c3 ("ath5k: Update reset code") subtly changed the
code that computes floating point values for the PHY3_TIMING register
such that the exponent is off by a decimal point, which can cause
problems with OFDM channel operation.
get_bitmask_order() actually returns the highest bit set plus one,
whereas the previous code wanted the highest bit set. Instead, use
ilog2 which is what this code is really calculating. Also check
coef_scaled to handle the (invalid) case where we need log2(0).

AR5K_PHY_PLL_40MHZ_5413 should not be ORed with AR5K_PHY_MODE_RAD_RF5112
for 5 GHz channels.
The incorrect PLL value breaks scanning in the countries where 5 GHz
channels are allowed.

iwlagn rate scaling will periodically search other rate scale
tables to switch to the best table regarding performance. In the past
the number of search tables were 3. Every time the rate scale algorithm
goes through these available tables in will stay in current table for
some time before start searching again. Recent driver support more
feature and antenna, so we have more tables to search. This patch make
sure we go through all available tables.

This removes all the dead code that tries to adjust the power
saving level based on the system AC state (inacceptable policy
in the kernel) or based on overtemp conditions (unused).
Also, pass _all_ policy wrt. enabling PS to mac80211, since
we do not use the power_disabled internally I now use that to
mirror the mac80211 CONF_PS setting. When mac80211 turns off
CONF_PS we follow suit. This means that the user power level
(which can currently only be set from sysfs) is not touched
for mac80211 powersave changes.
This means no "association status" checks are necessary since
mac80211 will not allow power save to be enabled when not
associated.

iwlwifi internally needs to keep track of whether PS
is enabled in the firmware or not. To do this, it keeps
a bit in the status flags, called STATUS_POWER_PMI.
The code to set this bit looks as follows:
static int iwl_set_power(struct iwl_priv *priv, void *cmd)
{
return iwl_send_cmd_pdu_async(priv, POWER_TABLE_CMD,
sizeof(struct iwl_powertable_cmd),
cmd, NULL);
}
int iwl_power_update_mode(...)
{
[...]
if (final_mode != IWL_POWER_MODE_CAM)
set_bit(STATUS_POWER_PMI, &priv->status);
iwl_update_power_cmd(priv, &cmd, final_mode);
cmd.keep_alive_beacons = 0;
if (final_mode == IWL_POWER_INDEX_5)
cmd.flags |= IWL_POWER_FAST_PD;
ret = iwl_set_power(priv, &cmd);
if (final_mode == IWL_POWER_MODE_CAM)
clear_bit(STATUS_POWER_PMI, &priv->status);
else
set_bit(STATUS_POWER_PMI, &priv->status);
if (priv->cfg->ops->lib->update_chain_flags && update_chains)
priv->cfg->ops->lib->update_chain_flags(priv);
[...]
}
Now, this bit really needs to track what the _firmware_
thinks, not what the driver thinks. Therefore, there is
a race condition here -- the driver sets the bit before
it knows that the async command sent to the card in the
iwl_set_power function has been processed. As a result,
the call to update_chain_flags() may think that the card
has been woken up (PMI bit cleared) while in reality it
hasn't processed the async POWER_TABLE_CMD yet.
This leads to bugs -- any commands the update_chain_flags
function sends can get stuck and subsequent commands also
fail.
The fix is almost trivial: since there's no reason to send
an async command here (in fact, there almost never should
be since many mac80211 callbacks can sleep) just make the
function wait for the card to process the command and then
return and clear the PMI bit.
