27ae60f8f7 ipw2x00: replace "ieee80211" with "libipw" where appropriate
"ieee80211" was the old name of the common library for ipw2100 and
ipw2200.  It was renamed to "libipw", but some occurrences of the old
name remained.

Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to
free_libipw().  Adjust comments and label names.  Change prefixes in
diagnostic messages.

Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface.

Move the affected EXPORT_SYMBOL macros to their proper places.

3f9e750d13 wl1251: fix ELP_CTRL register accesses when using SDIO
For some unknown reason ELP_CTRL can't be accesed using

 wl1251: ERROR sdio write failed (-110)

To fix this, add special IO functions for ELP_CTRL access that are

eaf55530c9 mac80211: optimize tx status processing
When a cooked monitor interface is active, ieee80211_tx_status()
generates a radiotap header for every single frame, even if it wasn't
injected and thus won't be sent to a monitor interface.
This patch reduces cpu utilization by moving the cooked monitor check a
bit earlier, before it generates the rtap header.

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

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

rndis_query_oid() uses full output buffer size to copy response buffer
from rndis_command()/device. This doesn't cause problems as response buffer

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

c2ef355bf3 mac80211: give warning if building w/out rate ctrl algorithm
I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack
and drivers w/ no rate control algorithm.  For drivers like RTL8187 that don't
supply their own RC algorithms, this will cause ieee80211_register_hw to
fail (making the driver unusable).

This will tell kconfig to provide a warning if no rate control algorithms
have been selected.  That'll at least warn the user; users that know that
their drivers supply a rate control algorithm can safely ignore the
warning, and those who don't know (or who expect to be using multiple
drivers) can select a default RC algorithm.

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.

iwl_apm_stop_master and iwl_internal_short_hw_scan
are only used within iwlcore and thus do not need to be exported.

72e15d71b0 iwlwifi: change WEP key protection to use mutex
For later station notification support we would like WEP key setting to be
done synchronously always. Currently all places from which WEP key is set
can sleep, but the usage of sta_lock prevents it to do so. Modify the
locking to use priv->mutex instead and thus enable this call to sleep.
