ac5215a7d1 wifi: iwlwifi: mld: force the responder to use the full bandwidth 
When a soft AP is started, it may not use the full configured
bandwidth (e.g. if no station is connected). As a result, the
responder will not support the configured bandwidth. Since the
responder supports ranging with unassociated stations, there is
no indication to the driver when the full bandwidth should be enabled.
Fix it by configuring the AP to always use the full bandwidth when a
responder is supported.

94f086a4db wifi: iwlwifi: mld: start AP with the correct bandwidth 
When a channel context is added, it is still not assigned to the link
and the link is not yet active. As a result, the channel context
min_def is used when the AP is started, even when the full bandwidth

Fix it by updating the PHY channel context when the link is already

822c7bd5ef wifi: iwlwifi: implement TOP reset follower 
For the upcoming SC hardware, a new reset mode "(silent) TOP
reset" will be available. When BT initiates that reset, it'll
negotiate with the WiFi firmware which makes it appear to the
driver as the reset interrupt. To distinguish it from all the
other reasons for the reset interrupt, there's (now) a status
field in CSR 0x110.

Implement the part of TOP reset where we react to BT doing it.
This requires disambiguating the interrupt, depending on the
state of the device, since we can even get TOP reset from BT
while waiting for the reset handshake.

If TOP reset is done by BT while we're not trying to do reset
anyway, then simply reprobe, since we cannot keep the state
of the device as it's being reset, after waiting the needed
180ms to let the device reset/settle.

eda436c2c5 wifi: iwlwifi: mld: simplify iwl_mld_rx_fill_status() 
Move some code that's only done when having received data out
of iwl_mld_rx_fill_status() and remove the two arguments that
are related to that. This simplifies the function for the no-
data case.

c561ac93cd wifi: iwlwifi: mld: skip unknown FW channel load values 
The firmware statistics were previously reporting bogus/old
channel load values if the device hadn't been active on a
given channel; it'll report an unknown value now for those
statistics affected (channel_load and channel_load_not_by_us.)
Handle that by simply skipping the value, the averaging would
result in the exact same value as before.

f600832794 wifi: mac80211: restructure tx profile retrieval for MLO MBSSID 
For MBSSID, each vif (struct ieee80211_vif) stores another vif
pointer for the transmitting profile of MBSSID set. This won't
suffice for MLO as there may be multiple links, each of which can
be part of different MBSSID sets. Hence the information needs to
be stored per-link. Additionally, the transmitted profile itself
may be part of an MLD hence storing vif will not suffice either.
Fix MLO by storing an instance of struct ieee80211_bss_conf
for each link.

Modify following operations to reflect the above structure updates:
- channel switch completion
- BSS color change completion
- Removing nontransmitted links in ieee80211_stop_mbssid()
- drivers retrieving the transmitted link for beacon templates.

37523c3c47 wifi: nl80211: add link id of transmitted profile for MLO MBSSID 
During non-transmitted (nontx) profile configuration, interface
index of the transmitted (tx) profile is used to retrieve the
wireless device (wdev) associated with it. With MLO, this 'wdev'
may be part of an MLD with more than one link, hence only
interface index is not sufficient anymore to retrieve the correct
tx profile. Add a new attribute to configure link id of tx profile.

53160d0edf wifi: cfg80211: Add support to get EMLSR capabilities of non-AP MLD 
The Enhanced multi-link single-radio (EMLSR) operation allows a non-AP MLD
with multiple receive chains to listen on one or more EMLSR links when the
corresponding non-AP STA(s) affiliated with the non-AP MLD is (are) in
the awake state. [IEEE 802.11be-2024, (35.3.17 Enhanced multi-link
single-radio (EMLSR) operation)]

An MLD which intends to enable EMLSR operations will set the EML
Capabilities Present subfield to 1 and shall set the EMLSR Support
subfield in the Common Info field of the Basic Multi-Link element to 1 in
all Management frames that include the Basic Multi-Link element except
Authentication frames. EML capabilities contains information such as
EML Transition timeout, Padding delay and Transition delay. These fields
needs to updated to drivers to trigger EMLSR operation and to transmit and
receive initial control frame and data frames.

Add support to receive EML Capabilities subfield that non-AP MLD
advertises during (re)association request and send it to underlying
drivers during ADD/SET station.

Due to this, mac80211 should handle transmitting multicast frames on
