e9f08381cb ath5k: fixing retries in ath5k_hw_setup_4word_tx_desc
The rate control algorithm, default is Minstrel for ath5k, determines
the number of retries to use for each rate.  However, there exists in
ath5k_hw_setup_4word_tx_desc (which is called for AR5212 like devices)
a set number of retries defined by AR5K_TUNE_HWTXTRIES.  The set
number of tries is added to the tx_tries0 variable setup by the rate
control algorithm.  This changes the number of retries the rate
control algorithm considers necessary.  By removing the
AR5K_TUNE_HWTXTRIES from the retry calculation the rate control
algorithm is given control over the number of retries.

d969847c22 ath9k: fix rate control tx status handling for A-MPDU
Currently the rate control tx status update gets called for every
subframe of an A-MPDU, and ath9k marks the frame with the relevant
status update with an internal flag. This not suitable for rate control
algorithms using the standard mac80211 rate control API, so fix this by
using IEEE80211_TX_STAT_AMPDU for marking the correct frames that
should be processed.

687c8ff12d ath5k: Minor EEPROM documentation updates
Here are some minor updates for EEPROM, mostly documentation and some small
fixes which have no effect at the moment.

- fixed_bias is not available for B mode.

- AR5K_EEPROM_[RT]X_CHAIN_DIS is 3 bit. this is MIMO and will not be used in
  ath5k, but just to be correct.

- AR5K_EEPROM_JAP_MID_EN added, and shift of following flags adapted.

also be used to set the antenna mode until we have proper support for that in

rndis_query_oid() uses full output buffer size to copy response buffer
from rndis_command()/device. This doesn't cause problems as response buffer
is sized based on output buffer but does copy extra unset bytes.
So change rndis_query_oid() so that only meaningful bytes are being copied.

Also in case of malfunctioning device/cable/etc returned data offset from
device might be wrong so bound check memory access correctly, so add
checks for this.

8127fbdc41 ath5k: Fix TX/RX padding for all frames
Currently, the padding position is based on
ieee80211_get_hdrlen_from_skb(). This is not correct since the HW does
padding on RX (and expect the same padding to be present on TX) at the
following position :

- management : 24 + 6 if 4-addr format
- control    : 24 + 6 if 4-addr format
- data       : 24 + 6 if 4-addr format + 2 if QoS
- invalid    : 24 + 6 if 4-addr format

whereas ieee80211_get_hdrlen_from_skb() is :

- management : 24
- control    : 16 except for ACK/CTS where it is 10
- data       : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order
- invalid    : 24

So, correct frames are not affected : management frames do not use
4-addr format, control frames have no body and invalid frames are ...
not valid by definition. However, in order to use monitor interface for
debugging purpose, one must be able to send/receive any frames, be it
correct or not. Such frames are affected by incorrect padding.

Moreover, since padding is added on TX, we need to remove it before
calling ieee80211_tx_status. This affect TX packets received by monitor
interfaces.

It has been tested between an ath5k based card (AR5212) and an ar9170usb
based card (netgear WNDA3100) using a frame generator and a monitor
interface for each card.

v2: Added ath5k_add_padding / ath5k_remove_padding

edc1a3a090 iwlwifi: clean up queue/fifo handling
4965 hardware has 7 queues reserved and the
remaining ones used for aggregation, 5000
and higher need to have 10 reserved. This
is not very clear in the code right now,
unfortunately.

Introduce a new IWL_TX_FIFO_UNUSED constant
and make the queue/FIFO mapping arrays able
to hold that value, and change the setup
code to reserve all queues in the arrays
(the queue number is the index) and use the
new unused constant to not map those queues
to any FIFO.

Additionally, clear up the AC/queue mapping
code to be more understandable. The mapping
is the identity mapping right now, but with
the mapping function I think it's easier to
understand what happens there.

Finally, HCCA isn't implemented at all and
I think newer microcode removed it, so let's
remove all mention of it in the code, some
comments remain for 4965.

4fa0043731 mac80211: Fix HT rate control configuration
Handling HT configuration changes involved setting the channel
with the new HT parameters and then issuing a rate_update()
notification to the driver.

This behavior changed after the off-channel changes. Now, the channel
is not updated with the new HT params in enable_ht() - instead, it
is now done when the scan work terminates. This results in the driver
depending on stale information, defaulting to non-HT mode always.

Fix this by passing the new channel type to the driver.

b08dfd0435 iwlwifi: load firmware asynchronously before mac80211 registration
At the wireless summit in Portland we discussed a way of
loading firmware asynchronously from ->probe() before
registration to mac80211, in order to register with the
wireless subsystems with complete information in cases
where firmware is required to know parameters.

This is not yet the case in iwlwifi, but for some new
features we're working on it will be the case since
those will only be supported by new firmware images.

Hence, to start with, convert iwlwifi to load firmware
asynchronously from probe, unbinding the device when
firmware loading fails, and only registering with the
wireless subsystems after firmware has been loaded
successfully.

Future patches will hook into this to register the
new firmware capabilities, depending on the firmware
API version.

a9f042cbe5 ath9k: fix lockdep warning when unloading module
Since txq->axq_lock may be hold in softirq context, it must be
acquired with spin_lock_bh() instead of spin_lock() if softieq is
enabled.

The patch fixes the lockdep warning below when unloading ath9k modules.

86baf71229 zd1211rw: fix potential array underflow
The first chunk fixes a debugging assert to print a warning about array underflows.
The second chunk corrects a potential array underflow.  I also removed an assert
in the second chunk because it can no longer happen.

6510b89179 airo: return from set_wep_key() when key length is zero
Even if keylen == 0 is a bug and should not really happen, better avoid
possibility of passing bad value to firmware.

f31e50a802 be2net: fix tx completion polling
In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
but before re-enabling interrupts (via a cq notify).
