ath9k: fix beacon timer restart after a card reset
In AP mode, ath_beacon_config_ap only restarts the timer if a TSF
restart is requested. Apparently this was added, because this function
unconditionally sets the flag for TSF reset.
The problem with this is, that ath9k_hw_reset() clobbers the timer
registers (specified in the initvals), thus effectively disabling the
SWBA interrupt whenever a card reset without TSF reset is issued
(happens in a few places in the code).
This patch fixes ath_beacon_config_ap to only issue the TSF reset flag
when necessary, but reinitialize the timer unconditionally. Tests show,
that this is enough to keep the SWBA interrupt going after a call to
ath_reset()

nl80211: add power save commands
The most needed command from nl80211, which Wireless Extensions had,
is support for power save mode. Add a simple command to make it possible
to enable and disable power save via nl80211.
I was also planning about extending the interface, for example adding the
timeout value, but after thinking more about this I decided not to do it.
Basically there were three reasons:
Firstly, the parameters for power save are very much hardware dependent.
Trying to find a unified interface which would work with all hardware, and
still make sense to users, will be very difficult.
Secondly, IEEE 802.11 power save implementation in Linux is still in state
of flux. We have a long way to still to go and there is no way to predict
what kind of implementation we will have after few years. And because we
need to support nl80211 interface a long time, practically forever, adding
now parameters to nl80211 might create maintenance problems later on.
Third issue are the users. Power save parameters are mostly used for
debugging, so debugfs is better, more flexible, interface for this.
For example, wpa_supplicant currently doesn't configure anything related
to power save mode. It's better to strive that kernel can automatically
optimise the power save parameters, like with help of pm qos network
and other traffic parameters.
Later on, when we have better understanding of power save, we can extend
this command with more features, if there's a need for that.

This change monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the expected_
ack_count also drops. At the same time, the aggregated ba_timeout (the number
of ba timeout retries) also rises. If the actual_ack_count/expected_ack_count
ratio is 0 and the number of ba timeout retries rises to 16, no tx packets
(tcp, udp, or ping - icmp) can be delivered. The driver recovers from this
situation by reseting the uCode firmware. If the actual_ack_count/expected_

retries just exceed 5 (but not 16), then the driver can reset the radio to

ath9k: fix keycache leak in split tkip case
If split tkip key is used, ath_delete_key should delete
rx key and rx mic key. This patch fixes the leak of hw
keycache in the case.

mac80211: fix deauth race
When userspace requests a deauth while the
authentication work is pending in the auth
(not probe) state, we do not properly abort
the work and then things get confused.
Fix that and also improve the checks here
to include the correct virtual interface,
just in case two virtual interfaces would
ever try to connect to the same BSS.
Also fix a bug -- need to use list_del_rcu
instead of just list_del to free a work
item.

iwlwifi: Send broadcast probe request only when asked to
When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

iwlwifi: Add chain_noise support for 6050
Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset). As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

libertas: don't retry commands
Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.
Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.
