678b385d07 iwlwifi: default max event log size
Size of event log is determined by uCode which is different per NICs.
Set the maximum event log size per device to better match uCode
configuration.

68dd5b7a45 mac80211: check whether scan is in progress before queueing scan_work
As scan_work is queued from work_work it needs to be checked if scan
has been started during execution of work_work. Otherwise, when hw
scan is used, the stack gets error about hw being busy with ongoing
scan. This causes the stack to abort scan without notifying the driver
about it. This leads to a situation where the hw is scanning and the stack
thinks it's not. Then when the scan finishes, the stack will complain by
warnings.

a05988bbbe ath5k: fix race condition in tx desc processing
As pointed out by Benoit Papillault, there is a potential
race condition between the host and the hardware in reading
the next link in the transmit descriptor list:

cpu0              hw
                  tx for buf completed
                  raise tx_ok interrupt
process buf
buf->ds_link = 0
                  read buf->ds_link

This change checks txdp before processing a descriptor
(if there are any subsequent descriptors) to see if
hardware moved on.  We'll then process this descriptor on
the next tasklet.

Review spotted a couple of strange invocations to
ieee80211_wake_queues that could potentially cause problems:

 - queues are awakened in the calibration tasklet before
   phy calibration, and then again after calibration

 - queues are awakened inside reset when we're trying to
   drain the ath5k transmit queues, and again after
   reset is completed (in callers to ath5k_reset_wake).

In both cases the first wake is unnecessary, so remove it.

098a607091 mac80211: clean up/fix aggregation code
The aggregation code has a number of quirks, like
inventing an unneeded WLAN_BACK_TIMER value and
leaking memory under certain circumstances during
station destruction. Fix these issues by using
the regular aggregation session teardown code and
blocking new aggregation sessions, all before the
station is really destructed.

As a side effect, this gets rid of the long code
block to destroy aggregation safely.

Additionally, rename tid_state_rx which can only
have the values IDLE and OPERATIONAL to
tid_active_rx to make it easier to understand
that there is no bitwise stuff going on on the
RX side -- the TX side remains because it needs
to keep track of the driver and peer states.

Wait for an RCU grace period to elapse before
finishing destroying the station after we have
removed the station from the driver and from
the hash table etc., even in the case where no
key is associated with the station.

Also, there's no point in deleting the plink

d5cdfacb35 cfg80211: Add local-state-change-only auth/deauth/disassoc
cfg80211 is quite strict on allowing authentication and association
commands only in certain states. In order to meet these requirements,
user space applications may need to clear authentication or
association state in some cases. Currently, this can be done with
deauth/disassoc command, but that ends up sending out Deauthentication
or Disassociation frame unnecessarily. Add a new nl80211 attribute to
allow this sending of the frame be skipped, but with all other
deauth/disassoc operations being completed.

Similar state change is also needed for IEEE 802.11r FT protocol in
the FT-over-DS case which does not use Authentication frame exchange
in a transition to another BSS. For this to work with cfg80211, an
authentication entry needs to be created for the target BSS without
sending out an Authentication frame. The nl80211 authentication
command can be used for this purpose, too, with the new attribute to
indicate that the command is only for changing local state. This
enables wpa_supplicant to complete FT-over-DS transition successfully.

2111ac0d88 ath5k: Adaptive Noise Immunity (ANI) Implementation
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked
at both ath9k and HAL sources (they are nearly the same), and even though i
have implemented some things differently, the basic algorithm is practically
the same, for now. I hope that this can serve as a clean start to improve the
algorithm later.

This also adds a possibility to manually control ANI settings, right now only
thru a debugfs file:
  * set lowest sensitivity (=highest noise immunity):
	echo sens-low > /sys/kernel/debug/ath5k/phy0/ani
  * set highest sensitivity (=lowest noise immunity):
	echo sens-high > /sys/kernel/debug/ath5k/phy0/ani
  * automatically control immunity (default):
	echo ani-on > /sys/kernel/debug/ath5k/phy0/ani
  * to see the parameters in use and watch them change:
	cat /sys/kernel/debug/ath5k/phy0/ani

Manually setting sensitivity will turn the automatic control off. You can also
control each of the five immunity parameters (noise immunity, spur immunity,
firstep, ofdm weak signal detection, cck weak signal detection) manually thru
the debugfs file.

This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band.

50c500ad3d wl1271: Configure a higher listen interval to AP upon association
Increase the fixed listen-interval max value configured to the mac80211 on
driver init. This value will allow a larger value to be configured to the
AP, which means the AP will buffer our frames longer.

606c1487ac wl1271: Configure rates for templates
Configure meaningful rates to be used with the templates. For control frames,
use the determined basic rates (currently the lowest rate for the band) and
for data-frames (null-funcs) let the firmware use the current rate policy to
determine the rate.

ebba60c66b wl1271: Use minimum rate for each band for control messages
Currently the mac80211 is not telling a hardware rate controlled driver a
rate to use for association frames etc. So to be safe, use the lowest rate
of each band for communication.

40b359c61d wl1271: Fix keep-alive related command error
The firmware does not like the host configuring the keep-alive after it has
been once configured after a join-operation. Instead, it will complain about
invalid parameters, which do not break functionality, but do not look nice
in the syslog either.

This patch prevents the complaints by only configuring the keep-alive once
for an association, after the first time join is performed with the correct
bssid.

1ed95388ca wl1271: added missing command header in wl1271_cmd_disconnect
The command header was missing in the wl1271_cmd_disconnect structure.  It
was working fine by sheer luck, because the parameters are not critical and
because our wl1271_cmd_send() function was overwriting the rx_config_options
with the actual header.

This patch adds the header to the command structure.
