If a driver is given a wiphy and it wants to get to its private
mac80211 driver area it can use wiphy_to_ieee80211_hw() to get first
to its ieee80211_hw and then access the private structure via hw->priv. The
wiphy_priv() is already being used internally by mac80211 and drivers
should not use this. This can be helpful in a drivers reg_notifier().

This allows drivers to request strict regulatory settings to
be applied to its devices. This is desirable for devices where
proper calibration and compliance can only be gauranteed for
for the device's programmed regulatory domain. Regulatory
domain settings will be ignored until the device's own
regulatory domain is properly configured. If no regulatory
domain is received only the world regulatory domain will be
applied -- if OLD_REG (default to "US") is not enabled. If
OLD_REG behaviour is not acceptable to drivers they must
update their wiphy with a custom reuglatory prior to wiphy
registration.

Drivers may need more information than just who set the last regulatory domain,
as such lets just pass the last regulatory_request receipt. To do this we need
to move out to headers struct regulatory_request, and enum environment_cap. While
at it lets add documentation for enum environment_cap.

This patch adds a flag to notify drivers to start and stop
beaconing when needed, for example, during a scan run. Based
on Sujith's first patch to do the same, but now disables
beaconing for all virtual interfaces while scanning, has a
separate change flag and tracks user-space requests.

Since the standards only define 12 legacy rates, 32 is certainly
a sane upper limit and we don't need to use u64 everywhere. Add

The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.

A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to
add arbitrary IE data into the end of management frames. The interface
allows extra IEs to be configured for each management frame subtype, but
only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth,
Disassoc) are currently accepted in mac80211 implementation.
This makes it easier to implement IEEE 802.11 extensions like WPS and
FT that add IE(s) into some management frames. In addition, this can
be useful for testing and experimentation purposes.

If driver/firmware/hardware does not support CCMP for management
frames, it can now request mac80211 to take care of encrypting and
decrypting management frames (when MFP is enabled) in software. The

key is being configured for TX side and return the undecrypted frames
on RX side without RX_FLAG_DECRYPTED flag to use software CCMP for
management frames (but hardware for data frames).

When MFP is enabled, the AP does not allow a STA to associate if an
existing security association exists without first going through SA
Query process. When this happens, the association request is denied
with a new status code ("temporarily rejected") ans Association
Comeback IE is used to notify when the association may be tried again
(i.e., when the SA Query procedure has timed out).
Use the comeback time to update the mac80211 client MLME timer for
next association attempt to minimize waiting time if association is
temporarily rejected.

We add support for multiple drivers to provide a regulatory_hint()
on a system by adding a wiphy specific regulatory domain cache.
This allows drivers to keep around cache their own regulatory domain
structure queried from CRDA.
We handle conflicts by intersecting multiple regulatory domains,
each driver will stick to its own regulatory domain though unless
a country IE has been received and processed.
If the user already requested a regulatory domain and a driver
requests the same regulatory domain then simply copy to the
driver's regd the same regulatory domain and do not call
CRDA, do not collect $200.

This modifies hardware flags for powersave to support three different
flags:
* IEEE80211_HW_SUPPORTS_PS - indicates general PS support
* IEEE80211_HW_PS_NULLFUNC_STACK - indicates nullfunc sending in software
* IEEE80211_HW_SUPPORTS_DYNAMIC_PS - indicates dynamic PS on the device
It also adds documentation for all this which explains how to set the
various flags.
Additionally, it fixes a few things:
* a spot where && was used to test flags
* enable CONF_PS only when associated again

power_level in ieee80211_conf is being used for more than one
purpose. It being used as user configured power limit and the
final power limit given to the driver. By doing so, except very
first time, the tx power limit is taken from min(chan->max_power,
local->hw.conf.power_level) which is not what we want. This patch
defines a new memeber in ieee80211_conf which is meant only for
