Main use case is to measure the signal strength of a connected station
to AP. Data packet transmit rates and bandwidth used by station can vary
a lot even if the station is at fixed location, especially if the rates
used are multi stream(2stream, 3stream) rates with different bandwidth(20/40/80 Mhz).
These multi stream rates are sensitive and station can use different transmit power
for each of the rate and bandwidth combinations. RSSI measured from these RX packets
on AP will be not stable and can vary a lot with in a short time.
Whereas 802.11 ack frames from station are sent relatively at a constant
rate (6/12/24 Mbps) with constant bandwidth(20 Mhz).
So average rssi of the ack packets is good and more accurate.

This interface allows the host driver to offload the authentication to
user space. This is exclusively defined for host drivers that do not
define separate commands for authentication and association, but rely on
userspace SME (e.g., in wpa_supplicant for the ~WPA_DRIVER_FLAGS_SME
case) for the authentication to happen. This can be used to implement
SAE without full implementation in the kernel/firmware while still being
able to use NL80211_CMD_CONNECT with driver-based BSS selection.
Host driver sends NL80211_CMD_EXTERNAL_AUTH event to start/abort
authentication to the port on which connect is triggered and status
of authentication is further indicated by user space to host
driver through the same command response interface.
User space entities advertise this capability through the

Add an event that indicates that a connection is authorized
(i.e. the 4 way handshake was performed by the driver). This event
should be sent by the driver after sending a connect/roamed event.
This is useful for networks that require 802.1X authentication.
In cases that the driver supports 4 way handshake offload, but the
802.1X authentication is managed by user space, the driver needs to
inform user space right after the 802.11 association was completed
so user space can initialize its 802.1X state machine etc.
However, it is also possible that the AP will choose to skip the
802.1X authentication (e.g. when PMKSA caching is used) and proceed
with the 4 way handshake immediately. In this case the driver needs
to inform user space that 802.1X authentication is no longer required
(e.g. to prevent user space from disconnecting since it did not get
any EAPOLs from the AP).
This is also useful for roaming, in which case it is possible that
the driver used the Fast Transition protocol so 802.1X is not
required.
Since there will now be a dedicated notification indicating that the
connection is authorized, the authorized flag can be removed from the
roamed event. Drivers can send the new port authorized event right
after sending the roamed event to indicate the new AP is already
authorized. This therefore reserves the old PORT_AUTHORIZED attribute.

Drivers that initiate roaming while being connected to a network that
uses 802.1X authentication need to inform user space if 802.1X
authentication is further required after roaming.
For example, when using the Fast transition protocol, roaming within
the mobility domain does not require new 802.1X authentication, but
roaming to another mobility domain does.
In addition, some drivers may not support 802.1X authentication
(so it has to be done in user space), while other drivers do.
Add a flag to the roaming notification to indicate if user space is
required to do 802.1X authentication after the roaming or not.
This flag will only be used for networks that use 802.1X
authentication. For networks that do not use 802.1X authentication it
is assumed that no further action is required from user space after
the roaming notification.

Currently the connect event from driver takes all the connection
response parameters as arguments. With support for new features these
response parameters can grow. Use a structure to pass these parameters
rather than passing them as function arguments.

Change the SET CQM command's RSSI threshold attribute to accept any
number of thresholds as a sorted array. The API should be backwards
compatible so that if one s32 threshold value is passed, the old
mechanism is enabled. The netlink event generated is the same in both
cases.
cfg80211 handles an arbitrary number of RSSI thresholds but drivers have
to provide a method (set_cqm_rssi_range_config) that configures a range
set by a high and a low value. Drivers have to call back when the RSSI
goes out of that range and there's no additional event for each time the
range is reconfigured as there was with the current one-threshold API.
This method doesn't have a hysteresis parameter because there's no
benefit to the cfg80211 code from having the hysteresis be handled by
hardware/driver in terms of the number of wakeups. At the same time
it would likely be less consistent between drivers if offloaded or
done in the drivers.

The nl80211_nan_dual_band_conf enumeration doesn't make much sense.
The default value is assigned to a bit, which makes it weird if the
default bit and other bits are set at the same time.
To improve this, get rid of NL80211_NAN_BAND_DEFAULT and add a wiphy
configuration to let the drivers define which bands are supported.
This is exposed to the userspace, which then can make a decision on
which band(s) to use. Additionally, rename all "dual_band" elements
to "bands", to make things clearer.
