This enables configuring key_mgmt=NONE + mka_ckn + mka_cak.
This allows wpa_supplicant to work in a peer-to-peer mode, where peers
are authenticated by the pre-shared (CAK,CKN) pair. In this mode, peers
can act as key server to distribute keys for the MACsec instances.
This is what some MACsec switches support, and even without HW

Previously, the estimated throughput was used to enable roaming to a
better AP. However, this information was not used when considering a
roam to an AP that has better signal strength, but smaller estimated
throughput. This could result in allowing roaming from 5 GHz band to 2.4
GHz band in cases where 2.4 GHz band has significantly higher signal
strength, but still a lower throughput estimate.
Make this less likely to happen by increasing/reducing the minimum
required signal strength difference based on the estimated throughputs
of the current and selected AP. In addition, add more details about the
selection process to the debug log to make it easier to determine whaty
happened and why.

Add support to differentiate between station mode FT and AP mode FT in

This is specific to the macsec_qca driver. The core implementation
shouldn't care about this, and only deal with the complete secure
channel, and pass this down to the driver.
Drivers that have such limitations should take care of these in their
->create functions and throw an error.
Since the core MKA no longer saves the channel number, the macsec_qca
driver must be able to recover it. Add a map (which is just an array
since it's quite short) to match SCIs to channel numbers, and lookup
functions that will be called in every place where functions would get
the channel from the core code. Getting an available channel should be
part of channel creation, instead of being a preparation step.

When starting ASP provisioning with connection capability set to NEW,
don't create the pending P2P interface as a GO interface because
Go negotiation will determine which side will be the GO and it is
possible that eventually this interface will become the client.
In this case, when the P2P client is started it will start scanning
and do other station specific operations while the interface type
is AP.
Instead, use type WPA_IF_P2P_GROUP when creating the interface which
means the interface type will be determined later.

This was already done for most driver cases, but it is possible that the
BSSID/frequency is not forced if the driver reports BSS selection
capability (e.g., NL80211_ATTR_ROAM_SUPPORT). That could potentially
result in the driver ignoring the BSSID/frequency hint and associating
with another (incorrect) AP for the WPS provisioning step if that
another AP in the same ESS is more preferred (e.g., better signal
strength) by the driver and only one of the APs (the not preferred one)
is in active WPS registrar state.
While most drivers follow the BSSID hint for the initial connection to
an ESS, not doing it here for the WPS provisioning would break the
protocol. Fix this by enforcing a single BSSID/frequency to disallow the
driver from selecting an incorrect AP for the WPS provisioning
association.

PNO is sometimes restarted due to changes in scan parameters
(e.g., selected network changed or MAC randomization being
enabled/disabled). Restart is done by stopping PNO and immediately
starting it again. This may result in the SCHED_SCAN_STOPPED event being
received after the request for new PNO, which will make wpa_supplicant
believe PNO is not active although it is actually is. As a result, the
next request to start PNO will fail because PNO is active and should be
stopped first.
Fix this by deferring the request to start PNO until the
SCHED_SCAN_STOPPED event is received in case sched_scan is being
stopped.

In some cases, after a sudden AP disappearing and reconnection to
another AP in the same ESS, if another scan occurs, wpa_supplicant might
try to roam to the old AP (if it was better ranked than the new one)
because it is still saved in BSS list and the blacklist entry was
cleared in previous reconnect. This attempt is going to fail if the AP
is not present anymore and it'll cause long disconnections.
Remove an AP that is probably out of range from the BSS list to avoid
such disconnections. In particular mac80211-based drivers use the
WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY reason code in locally generated
disconnection events for cases where the AP does not reply anymore.
