b23709248f mac80211: Do not queue Probe Request frames for station MLME
Cooked monitor interfaces cannot currently receive Probe Request
frames when the interface is in station mode. However, we do not
process Probe Request frames internally in the station MLME, so there
is no point in queueing the frame here. Remove Probe Request frames
from the queued frame list to allow cooked monitor interfaces to
receive these frames.

2eb2fa67e5 ath5k: allow setting txpower to 0
As a holdover from earlier code when we used to set
the power limit to '0' after a reset to configure the
default transmit power, ath5k interprets txpower=0 as
12.5 dBm.  Fix that by just passing 0 through.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14567

634a555ce3 rndis_wlan: handle NL80211_AUTHTYPE_AUTOMATIC
rndis_wlan didn't know about NL80211_AUTHTYPE_AUTOMATIC and simple
setup with 'iwconfig wlan essid no-encrypt' would fail (ENOSUPP).

v2: use NDIS_80211_AUTH_AUTO_SWITCH instead of _OPEN.
    This will make device try shared key auth first, then open.

6a62e5ef94 rt2800: do not enable tbtt unless we are in a beacon mode
Please be gentle, I'm a fs developer and this is my first foray into drivers, as
I'm tired of building ralinks driver everytime I update my kernel.  Whenever I
load the rt2800pci driver my box bogs down, and a few printk's later I
discovered its because I was getting 10's of thousands of TBTT interrupts a
second.  I discovered this was because we were setting the beacon timer to 0,
which is apparently what TBTT keys off of.  It seems to me that we should only
be enabling TBTT when we are in a beacon transmitting mode, which from what I
can tell is in AD-HOC and other such modes where the mac80211 layer would have
given us a proper beacon_int to set the beacon timer to instead of 0.  So this
is my fix, only enable TBTT if our sync mode is for beacon.  This makes it so my
box doesn't die everytime I load the rt2800pci driver.  Let me know if this is
acceptable, I just learned all these terms about 15 minutes ago via wikipedia,
so I really am not familiar with how this stuff is supposed to work.  Thanks,

31a4cf1f22 rt2x00: Fix BUG on rt2800usb when trying to read eFuse EEPROM.
Current tree hits a BUG_ON in rt2x00_regbusy_read, because the eFuse EEPROM
reading code of rt2800lib uses the function without the csr_mutex locked.

Fix this by locking the csr_mutex for the of the EEPROM reading cycly and
using the _lock variants of the register reading and writing functions.

This also introcudes the register_read_lock function pointer in the
rt2800_ops structure.

16475b095a rt2x00: Log RT/RF chipset information correctly.
Some drivers (rt2800* most notably) cannot set the RF and RT chipset in
the correct order to have the information logging in rt2x00_set_chip
be correct.
Fix this by decoupling the setting of the chipset information from the
logging of the chipset information so that drivers can determine
themselves when all information is set.

61fa713c75 cfg80211: return channel noise via survey API
This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
ops that a driver can implement. The goal of this command is to allow a
drivers to report channel survey data (e.g. channel noise, channel
occupation).

For now, only the mechanism to report back channel noise has been
implemented.

In future, there will either be a survey-trigger command --- or the existing
scan-trigger command will be enhanced. This will allow user-space to
request survey for arbitrary channels.

Note: any driver that cannot report channel noise should not report
any value at all, e.g. made-up -92 dBm.

The max MCS index is 76, fix the higher check to allow through
frames received at MCS 76. This is a non-issue for current drivers
as MCS 76 is only possible with a device supporting 4 spatial
streams.

While at it change the WARN_ON() on invalid HT rates to a WARN()
to provide more useful information. This will help debug issues
when the driver is passing up a bogus HT rate value.

The rate must map to a valid MCS index which can be any of the
values in the set [0 - 76] (inclusive).

ieee80211_rx_status->qual has been marked deprecated.
This allows us to remove several functions and fields which
were used to calculate a reasonable value for it.

a65986824d rt2x00: Add dynamic detection of eFuse EEPROM in rt2800pci.
Instead of assuming that all rt3090 devices will have an eFuse EEPROM,
do as the legacy Ralink driver, and detect at run-time whether an
eFuse EEPROM is present.

748d451028 ath9k_common: clarify and correct jumbogram processing
Jumbograms are frames put together linked together through
more than one descriptor. For example ath9k_htc will use this
to send from the target a large frame split up into 2 or more
segments. The driver then would be in charge of putting the
frame back together.

When jumbograms are constructed the rx_stats->rs_more will
bet set and rx_stats->rs_status will not have any valid content
as the actual status will only be avialable at the end of
the chained descriptors.

165864d087 ath9k_common: remove ath9k_compute_qual()
This is now deprecated and unused within mac80211, so time
to remove it as otherwise we'd be doing some unecessary
computations for nothing.

db86f07ec6 ath9k_common: add new module to share 802.11n driver helpers
ath9k and ath9k_htc share a lot of common hardware characteristics.
They only differ in that ath9k_htc works with a target CPU and ath9k
works directly with the hardware. ath9k_htc will do *some* things in
the firmware, but a lot of others on the host.

The common 802.11n hardware code is already shared through the ath9k_hw
module. Common helpers amongst all Atheros drivers can use the ath module,
this includes ath5k and ar9170 as users. But there is some common driver
specific helpers which are not exactly hardware code which ath9k and
ath9k_htc can share. We'll be using ath9k_common for this to avoid
bloating the ath module and the common 802.11n hardware module ath9k_hw.

We start by sharing skb pre and post processing in preparation for a hand
off to mac80211.
