An AP might refuse to connect a STA if it has a low RSSI. In such case,
the AP informs the STA with the desired RSSI delta and a retry timeout.
Any subsequent association attempt with that AP (BSS) should be avoided,
unless the RSSI level improved by the desired delta or the timeout has
expired.
Defined in Wi-Fi Alliance Optimized Connectivity Experience technical
specification v1.0, section 3.14 (RSSI-based association rejection
information).

Advertise vendor specific Multi-AP IE in (Re)Association Request frames
and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame
does not contain the Multi-AP IE, disassociate.
This adds a new configuration parameter 'multi_ap_backhaul_sta' to
enable/disable Multi-AP functionality.
Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in
wpa_drv_if_add(), which only gets called when an interface is added
through the control interface, not when it is configured from the
command line.

Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".
This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.
Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).
Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).
Tested with nl80211 DFS offload implementation.

There could be multiple pending TX operations and if the earlier ones
have used wait_time, but the last one did not, the driver call for
canceling pending wait was not done. This could result in the driver
getting stuck waiting for the previously scheduled wait time and not
being able to do new operations until that. Fix this by canceling the
wait if any of the past offchannel_send_action() calls since the last
offchannel_send_action_done() used non-zero wait_time.
This was showing up as issues in certain DPP Public Action frame
sequences when the same offchannel operation is used with multiple
frames and the last frame in the sequence does not need wait_time.

These commnds are mesh version of PMKSA_GET/ADD commands. So the usage

commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.
The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.
