When STA is performing roam from WPA3 AP to WPA2 AP, the STA was
including key mgmt FT-SAE instead of FT-PSK in FT Authentication request
RSNE when using driver-based SME. This is because the RSNE/MDE/FTE were
updated and forwarded to the driver using the NL80211_CMD_UPDATE_FT_IES
command before updating key mgmt properly. Because of this, the AP is
rejecting FT Authentication request with WLAN_REASON_UNSPECIFIED reason
code which is due to the invalid keymgmt in RSNE.
Fix this by reordering IE population to happen earlier in the sequence
so that the updated key mgmt information can be provided when using
NL80211_CMD_UPDATE_FT_IES.

Android has a mechanism to extend the driver interface in vendor
specific ways. This implementation of the vendor interface is done in
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB). Extend this to allow the vendor
events to be provided to this library to facilitate the event
processing.
Introduce a new board configuration via
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB_EVENT) rather than reusing
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB) to enable this event handling in the
private library. This is to avoid compilation issues for
wpa_driver_nl80211_driver_event() with the already existing private
library implementations defined with
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB).

When an external scan is in progress on the same radio, delay the P2P

Add a handler to notify failures to fetch the scan results and provide
an option to override default behavior of requesting a new scan in one
second in such an error condition. Use this new handler mechanism to
continue the p2p_find operation (by invoking p2p_scan_res_handled) for
an interim scenario where the p2p_scan attempt fails to get the scan
results from the driver which can happen, e.g., if there are parallel
updates to the cfg80211 scan results.

If there is a disconnect command from wpa_supplicant immediately after
the driver sends a connection event to userspace but before that event
is received and processed by wpa_supplicant, wpa_supplicant processes
the disconnect command and a self-generated disconnected event first
followed by the connected event received from the driver. As a result
wpa_supplicant moves to the WPA_COMPLETED state. Whereas the driver
processes the disconnect command received from wpa_supplicant after it
sends the connected event and moves to the disconnected state. Due to
this race between the disconnect command from wpa_supplicant and the
connected event from the driver, wpa_supplicant is moving to the
connected state though the driver is moving to the disconnected state
which results in abnormal functionality.
Ignore the connection event coming from the driver when wpa_supplicant
is not trying to connect after a disconnect command is issued but before
the next connect command is issued to fix the above mentioned race
condition.

When the driver sends a CQM RSSI threshold event, wpa_supplicant queries
the driver for the signal and noise values. However, it is possible that
by that time the station has already disconnected from the AP, so these
values are no longer valid. In this case, indicate that these values are
invalid by setting them to WPA_INVALID_NOISE.
Previously a value of 0 would be reported, which may be confusing as
this is a valid value.
Since nl80211_get_link_signal() and nl80211_get_link_noise() already set
invalid values for a case of failure, just use the value set by these
functions even if they fail.

Add initial_freq_list to wpa_supplicant configuration. This option
allows wpa_supplicant to scan a smaller list of frequencies when it
starts. This in turn allows for a faster connection to an already known
network. This limit applies only for the initial scan operation and does
not restrict other channels from being used in consecutive scans.
Tests have shown this to reduce the amount of time for connecting to a
network from roughly 3 seconds to roughly 0.1 second.

The hostapd DFS code deinitializes and initializes the AP interface, if
a clean channel switch is not possible. In this case the AP code paths
would deinit the driver, for example nl80211, without wpa_supplicant
code paths getting notice of this.
Therefore add callbacks for wpa_supplicant mesh methods, which are
called on init/deinit of the AP BSS. These callbacks are then used to
handle the reset in the mesh code.

Mesh join function is the last function to be called during mesh join
process, but it's been called a bit earlier than it's supposed to be, so
that some mesh parameter values such as VHT capabilities were not
applied correct when mesh join is in process. Moreover, the current
design of mesh join that is called directly after mesh initialization
isn't suitable for DFS channels to use, since mesh join process should
be paused until DFS CAC is done and resumed after it's done.
The callback will be called by hostapd_setup_interface_complete_sync().
There is a possibility that completing mesh init fails, so add error
handling codes for that.

If the maximum operating channel width for AP/P2P GO is not specified,
it is auto-selected during configuration. While selecting the channel
width, if VHT is supported and 160 MHz channels are available, 160 MHz
channel width is preferred to 80 MHz.
During the selection of the channel width, the corresponding driver
capabilities were not checked. As a result, the AP/P2P GO configuration
was set to use the available 160 MHz channels even if the driver did not
have capability to support the 160 MHz channel width causing failure to
start the AP/P2P GO.
Fix this by checking the driver support for the 160 MHz channel width
while selecting the channel width for AP/P2P GO.
