Add nl80211 and driver API to validate, add and delete traffic
streams with appropriate settings.
The API calls for userspace doing the action frame handshake
with the peer, and then allows only to set up the parameters
in the driver. To avoid setting up a session only to tear it
down again, the validate API is provided, but the real usage
later can still fail so userspace must be prepared for that.

Since we have no other monitoring facility to indicate the

This patch improves the way minstrel_ht sorts rates according to throughput
and success probability. 3 FOR-loops across the entire rate and mcs group set
in function minstrel_ht_update_stats() which where used to determine the
fastest, second fastest and most robust rate are reduced to 2 FOR-loop.
The sorted list of rates according throughput is extended to the best four
rates as we need them in upcoming joint rate and power control. The sorting
is done via the new function minstrel_ht_sort_best_tp_rates(). The annotation
of those 4 best throughput rates in the debugfs file rc-stats is changes to:
"A,B,C,D", where A is the fastest rate and C the 4th fastest.

Linux already supports 802.11h, where the access point can tell the
client to reduce its transmission power. However, 802.11h is only
defined for 5 GHz, where the need for this is much smaller than on
2.4 GHz.
Cisco has their own solution, called DTPC (Dynamic Transmit Power
Control). Cisco APs on a controller sometimes but not always send
802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support
for parsing and honoring the DTPC IE in addition to the 802.11h
element (they do not always contain the same limits, so both must
be honored); the format is not documented, but very simple.
Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet
1142 joined to a Cisco 2504 WLC, by setting various transmit power
levels for the given access points and observing the results.
The Wireshark 802.11 dissector agrees with the interpretation of the
element, except for negative numbers, which seem to never happen
anyway.

commit "mac80211: disable 40MHz support in case of 20MHz AP"
broke working VHT in 20Mhz with APs like Netgear R6300v2 which
do not publish support for 40Mhz but allow use of VHT in 20Mhz.
The break is because VHT is disabled once no HT cap doesn't indicate
support for 40Mhz. This causes the assoc request to be sent without
any VHT IE and the association is only HT due to this.

There are a few possible cases of where BSS data came from:
1) only a beacon has been received
2) only a probe response has been received
3) the driver didn't report what it received (this happens when
using cfg80211_inform_bss[_width]())
4) both probe response and beacon data has been received
Unfortunately, in the userspace API, a few things weren't there:
a) there was no way to differentiate cases 1) and 4) above
without comparing the data of the IEs
b) the TSF was always from the last frame, instead of being
exposed for beacon/probe response separately like IEs
Fix this by
i) exporting a new flag attribute that indicates whether or
not probe response data has been received - this addresses (a)
ii) exporting a BEACON_TSF attribute that holds the beacon's TSF
if a beacon has been received
iii) not exporting the beacon attributes in case (3) above as that
would just lead userspace into thinking the data actually came
from a beacon when that isn't clear
To implement this, track inside the IEs struct whether or not it
(definitely) came from a beacon.

Pull DEFINE_PCI_DEVICE_TABLE removal from Bjorn Helgaas:
"Part two of the PCI changes for v3.17:
- Remove DEFINE_PCI_DEVICE_TABLE macro use (Benoit Taine)
It's a mechanical change that removes uses of the
DEFINE_PCI_DEVICE_TABLE macro. I waited until later in the merge
window to reduce conflicts, but it's possible you'll still see a few"

pull request: wireless 2014-08-14
Please pull this batch of fixes intended for the 3.17 stream...
Arend van Spriel brings two brcmfmac fixes, one which fixes a memory
leak and one which corrects some merge damage.
Emmanuel Grumbach fixes Linus's iwlwifi firmware-related log spam.
Rickard Strandqvist does some proper NULL termination after a call
to strncpy.
Ronald Wahl corrects a carl9170 problem with sending URBs with the
wrong endpoint type (resulting in log spam).

Call rcu_deference_raw() directly from within rht_for_each_entry_rcu()
as list_for_each_entry_rcu() does.

No need to export rht_obj(), all inner to outer object translations
occur internally. It was intended to be used with rht_for_each() which
now primarily serves as the iterator for rhashtable_remove_pprev() to
effectively flush and free the full table.
