When processing a (Re)Association Request frame and no corresponding
station is found, try to find the station using the station MLD MAC
address from the Basic ML element, as it is possible that the station
is trying to re-associate but with a different link address (in such
a case the underlying driver would not perform address translations).
When sending the (Re)Association Response frame, use the addresses from
the (Re)Association Request frame and not the AP MLD MAC address, again,
to avoid the address translation done in the driver.

BSS load update is unrelated with the above two reasons, and therefore
is not the case to update beacon for co-location. Moreover, updating
beacon for co-location when BSS load update makes hostapd set beacon too

Implement processing of the Multi-Link element in the (Re)Association
Request frame, including processing of the Per-STA Profile subelement.
After handling the basic parsing of the element and extracting the
information about the requested links, handle the link specific
processing for each link:
- Find the interface with the corresponding link ID.
- Process the station profile in the interface.
- Prepare the Per-STA Profile subelement to be included in the
Multi-Link element in the (Re)Association Response frame.

In case the AP is an AP MLD, parse the Multi-Link element from the
Authentication frame, store the relevant information, and prepare the
response Multi-Link element.
If the AP is not an AP MLD or the parsing of the element fails, continue
the authentication flow without MLD support.
For SAE, it is needed to skip various fixed fields in
the Authentication frame. Implement it for SAE with H2E.
TODO: This should be extended to other authentication algorithms which
are allowed for MLD connections and have fixed fields in the
Authentication frames, according to IEEE P802.11-REVme/D3.0, Table 9-69
(Presence of fields and elements in Authentications frames).

Add support for including multiple hostapd interfaces in the same AP
MLD, i.e., all using the same underlying driver network interface.
To do so, when a new hostapd interface is added, if there is already
another interface using the same underlying network interface, associate
the new interface with the same private data object, instead of creating
a new one.
As some of the BSSs are non-first BSSs, meaning that they reuse the
drv_priv of the initial BSS, make sure not to double free it.
Currently multiple BSS entries are not supported so always use bss[0]
for MLD.

AP cannot come up in channels that are marked as NO_IR. If AP moves to
HAPD_IFACE_DISABLED state, it will deinitialize the nl80211 driver
interface and sockets.
Hence, introduce a new state called HAPD_IFACE_NO_IR, for 6 GHz APs to
handle NO_IR scenarios, such as AFC, where the channels not allowed by
AFC will have HOSTAPD_CHAN_NO_IR flag set. In this state, AP is still
kept in a non-operational state (stopped) without deinitializing the
nl80211 driver interface. wiphy reg change event can then update the
channels and bring up the AP in a valid channel.

Base AKM as PASN AKM if dot11NoAuthPASNActivated is false. That

Some station devices are apparently sending the EAPOL-Logoff message in
some cases before the initial authentication for WPA2/WPA3-Enterprise.
hostapd would have forced a "post EAP-Failure" disconnection in 10 ms
for such cases while still allowing the EAP authentication to try to
complete.
This is not ideal and could result in interoperability issues, so skip
the forced disconnection in the particular case where the EAPOL-Logoff
message is received before the first authentication is completed.
In addition, disconnect the STA without starting new EAP authentication
and the 10 ms delay if an EAPOL-Logoff message is received after
authentication has been completed successfully. This results in cleaner
behavior by avoiding the extra start of a new EAP authentication in a
case where the STA is going to be disconnected shortly.

When AP is brought up in HE40/EHT40 with ACS, the AP comes up with 20
MHz bandwidth. It is expected to come up with 40 MHz bandwidth.
conf->secondary_channel does not hold the correct value and it leads to
choosing 20 MHz in hostapd_set_freq_params(). conf->secondary_channel is
filled using the hostapd config he_oper_centr_freq_seg0_idx. When AP is
configured to use ACS, the hostapd config he_oper_centr_freq_seg0_idx is
not valid as the channel is not known during bring up. So using the
config he_oper_centr_freq_seg0_idx to fill the conf->secondary_channel
does not work with ACS.
Use op_class to determine the bandwidth and based on the bandwidth fill
the conf->secondary_channel to address this ACS case.

As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of
a nontransmitted BSSID profile, an EMA AP that transmits a Beacon
frame carrying a partial list of nontransmitted BSSID profiles
should include in the frame a Reduced Neighbor Report element
carrying information for at least the nontransmitted BSSIDs that
are not present in the Multiple BSSID element carried in that frame.
Add this support by splitting the reduced neighbor report (RNR) in as
many elements as the number of multiple BSSID elements. Each RNR element
excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will
have the data common for all EMA beacons such as neighbor AP information
gathered through neighbor reports.
The hwsim test case he_ap_ema demonstrates this support.

Once ACS picks a channel, iface->freq and iface->conf->channel are

after 'DISABLED' though ACS is configured.
But this will fail for 6 GHz APs since configured_fixed_chan_to_freq()
checks if iface->conf->channel is filled or not irrespective of ACS
configuration, and the checks inside configured_fixed_chan_to_freq()
fail the AP setup. Fix this by clearing iface->freq and
