Bluetooth: btmrvl: report error if verify_fw_download times out
FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.

Bluetooth: Fix sending write_le_host_supporte for LE-only controllers
The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.
This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

b43: HT-PHY: define regs for power estimation
In MMIO dumps of ndiswrapper there are following PHY ops:
phy_read(0x0118) -> 0x013d
phy_read(0x01ed) -> 0x993d
phy_read(0x0119) -> 0x012f
phy_read(0x01ee) -> 0x992f
phy_read(0x011a) -> 0x0139
phy_read(0x0969) -> 0x9939
It matches the code of wlc_phy_txpower_est_power_nphy (from brcm80211),
so we know the registers meaning.

b43: HT-PHY: do some extra TSSI setup after configuring TX
After b43_phy_ht_tx_power_ctl_setup there are some extra radio ops:
radio_read(0x08bf) -> 0x0001

ath9k: change DFS logging to use ath_dbg()
The DFS pattern detector was initially planned to reside on
a higher layer and used generic pr_*() logging functions.
Being part of ath9k, use ath_dbg() instead and make DFS log
ouput selectable via ATH_DBG_DFS (0x20000) at runtime.
This patch does not contain functional modifications.

rt2x00: Fix transmit power troubles on some Ralink RT30xx cards
Some cards on Ralink RT30xx chipset not have correctly TX_MIXER_GAIN
value in them EEPROM/EFUSE. In this case, we must use default value,
but always used EEPROM/EFUSE value. As result we have tranmitt power
range from -10dBm to +6dBm instead 0dBm to +16dBm.
Correctly value in EEPROM/EFUSE is one or more for RT3070 and two or
more for other RT30xx chips.
Tested on Canyon CNP-WF518N1 usb Wi-Fi dongle and Jorjin WN8020 usb
embedded Wi-Fi module.

mwl8k: remove nonstandard rate 72 Mbps
This rate causes an overflow in the extended rates IE's data rate field,
with the overflowing bit setting the Basic Rate Set membership. This
results in a bogus 8 Mpbs basic rate, making clients checking them refuse
association.
Since the rate is likely unused anyway (HT will yield better rates between
supporting chips), we can just remove it.
This fixes association from wpa_supplicant and Android 4.x and newer.

Samuel Ortiz <sameo@linux.intel.com> says:
"This is the 2nd NFC pull request for 3.10.
With this one we have:
- A major pn533 update. The pn533 framing support has been changed in order to
easily support all pn533 derivatives. For example we now support the ACR122
USB dongle.
- An NFC MEI physical layer code factorization through the mei_phy NFC API.
Both the microread and the pn544 drivers now use it.
- LLCP aggregation support. This allows NFC p2p devices to send aggregated
frames containing all sort of LLCP frames except SYMM and aggregation
frames.
- More LLCP socket options for getting the remote device link parameters.
- Fixes for the LLCP socket option code added with the first pull request for
3.10.
- Some support for LLCP corner cases like 0 length SDUs and general DISC
(tagged with a 0,0 dsap ssap couple) handling.
- RFKILL support for NFC."

mac80211: improve the rate control API
Allow rate control modules to pass a rate selection table to mac80211
and the driver. This allows drivers to fetch the most recent rate
selection from the sta pointer for already buffered frames. This allows
rate control to respond faster to sudden link changes and it is also a
step towards adding minstrel_ht support to drivers like iwlwifi.
When a driver sets IEEE80211_HW_SUPPORTS_RC_TABLE, mac80211 will not
fill info->control.rates with rates from the rate table (to preserve
explicit overrides by the rate control module). The driver then
explicitly calls ieee80211_get_tx_rates to merge overrides from
info->control.rates with defaults from the sta rate table.

cfg80211: introduce critical protocol indication from user-space
Some protocols need a more reliable connection to complete
successful in reasonable time. This patch adds a user-space
API to indicate the wireless driver that a critical protocol
is about to commence and when it is done, using nl80211 primitives
NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP.
There can be only on critical protocol session started per
registered cfg80211 device.
The driver can support this by implementing the cfg80211 callbacks
.crit_proto_start() and .crit_proto_stop(). Examples of protocols
that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the
link can/should be made more reliable is up to the driver. Things
to consider are avoid scanning, no multi-channel operations, and
alter coexistence schemes.
