ath12k_dp_rx_deliver_msdu() currently includes logic related to
monitor mode handling. This code was inherited from the ath11k driver,
where a single rx handler was used for both regular and monitor mode
packets. In ath12k, however, monitor mode packets are handled separately
via ath12k_dp_mon_rx_deliver_msdu(), which contains all the necessary
monitor-specific logic. Therefore, monitor-related checks and operations
in ath12k_dp_rx_deliver_msdu() are no longer needed. Remove this dead code
to simplify the rx path and avoid unnecessary per-packet checks.

As station, WCN7850 firmware requires pairwise key to be installed before
group key. Currently host does not care about this, so it is up to kernel
or userspace to decide which one will be installed first. In case above
requirement is not met, WCN7850 firmware's EAPOL station machine is messed
up, and finally connection fails [1].
Reorder key install for station interface in that case: this is done by
caching group key first; Later when pairwise key arrives, both can be
installed in required order.

If a regulatory notification is there in the system while the hardware is
being registered, it attempts to set the new regulatory country. However,
ath12k currently boots with a default country derived from the BDF. If this
default country differs from the one provided in the notification, a race
condition can occur while updating the regulatory information back to
userspace. This potentially leads to driver having the incorrect regulatory
applied.
For example, suppose the regulatory domain for France (FR) is already
applied, and then the driver is loaded with a BDF that has the United
States (US) country programmed. When the driver finishes loading, the
regulatory domain shown in phyX still reflects the US regulatory settings.
This is incorrect, as the driver had already received a notification for
FR during hardware registration, but failed to process it properly due to
the race condition.
The race condition exists during driver initialization and hardware
registration:
- On driver load, the firmware sends BDF-based country regulatory rules,
which are stored in default_regd via ath12k_reg_handle_chan_list().
- During hardware registration, a regulatory notification is triggered
through:
ath12k_mac_hw_register()
-> ieee80211_register_hw()
-> wiphy_register()
-> wiphy_regulatory_register()
-> reg_call_notifier()
This sends a country code to the firmware, which responds with updated
regulatory rules.
- After registration, ath12k_mac_hw_register() calls ath12k_regd_update(),
which copies default_regd and passes it to the upper layers.
The race occurs between the firmware's response and the execution of
ath12k_regd_update(). If the firmware's new rules are processed before the
update call, the correct values are used. Otherwise, outdated boot-time
country settings are exposed to userspace.
To resolve this issue, introduce a completion mechanism within the hardware
group (ah). Trigger this completion whenever a regulatory change is
requested from the firmware. Then, in ath12k_regd_update(), wait for the
firmware to complete its regulatory processing before proceeding with the
update.
This ensures that during driver load, the default country is processed
first. However, before ath12k_regd_update() is called, the new regulatory
notification will have already been received by the driver. As a result, it
will wait for the firmware's regulatory processing to complete, and only
the final, correct regulatory domain will be updated to userspace.

With previous patch [1], ath12k_reg_update_chan_list() will be called
during reg_process_self_managed_hint().
reg_process_self_managed_hint() will hold rtnl_lock all the time.
But ath12k_reg_update_chan_list() may increase the occupation time of
rtnl_lock, because when wait flag is set, wait_for_completion_timeout()
will be called during 11d/hw scan.
Should minimize the occupation time of rtnl_lock as much as possible
to avoid interfering with rest of the system. So move the update channel
list operation to a new worker, so that wait_for_completion_timeout()
won't be called with the rtnl_lock held.

When two split-phy devices that support overlapping frequency ranges within
the same band are grouped into an ath12k hardware (HW) setup, they share a
common wiphy instance. Consequently, the channel list (wiphy->bands[])
becomes unified across all associated radios (ar).
For reference, the devices are:
2.4 GHz + 5 GHz Low Band
5 GHz High Band + 6 GHz
The first radio probed within the 5 GHz range (say 5 GHz Low Band) updates
its sband reference (&ar->mac.sbands[NL80211_BAND_5GHZ]) within
wiphy->bands[]. However, when the second 5 GHz radio (5 GHz High Band) is
probed, it replaces the existing wiphy->bands[] entry with its own sub-band
reference. As a result, wiphy->bands[] always reflects the channel list
from the most recently probed radio in that band, restricting supported
channels to those within its specific range for upper-layer.
Fix this by updating the wiphy->bands[] to just enable the channels of
current radio when there exist a radio which already has set it.
This will make sure wiphy->bands[] holds reference of first radio which
got probed in 5 GHz band and subsequent radio just updates the channel list
in the same address space.
Since same sband memory space is shared between radios of a band, while
determining the allowed frequency range of radio, its frequency limits
(ar->freq_range.start_freq, end_freq) should be used.

When two split-phy devices having supported frequency range in same band
(as mentioned below) are combined into an ath12k HW group, they will be
part of same wiphy and hence the channel list (wiphy->bands[]) will be
common for all of the radios (ar).
1 - 2.4 GHz + 5 GHz Low band
2 - 5 GHz High band + 6 GHz
When a scan is triggered with frequency list containing frequencies of
both 5 GHz low and 5 GHz high, mac80211 generates a single scan request
to driver with both the frequencies. This is because mac80211 splits the
scan request based on band.
ath12k checks the first frequency in the requested scan frequency list and
initiates scan to corresponding radio's(ar) firmware with all the
frequencies. Firmware rejects this scan as some frequencies in the scan
request are not supported, resulting is scan failure.
Fix this by splitting the scan request into multiples scans in driver
based on the supported frequency range of different radios in a band and
schedule scans in parallel to them.
Finally send scan completion/abort notification to mac80211 after all the
radios complete their scheduled scan.
Also, last_scan_link is not needed anymore as ath12k internally schedules
multiple scans, remove the same and use ahvif->links_map to identify
scan links when scan is cancelled.

ath12k checks the first frequency in the requested scan frequency list and
initiates scan to corresponding radio's(ar) firmware with all the
frequencies. Firmware rejects this scan since some of the frequencies in
the scan request are not supported, resulting in a scan failure.
To fix this ath12k driver should split the scan request into multiple
scans based on requested frequencies and schedule them to corresponding
underlying radio(s) in parallel.
Currently, ath12k driver assigns the scan link (link 15) in ahvif->links[]
for scan vdev creation. However, with parallel scan support being
introduced in the following patch, multiple radios (e.g., 5 GHz low and
5 GHz high) in the same HW group may attempt to use the same scan link
concurrently, causing conflicts where the vdev created by one radio could
be deleted and re-initialized by another.
To address this, reserve space for additional scan links for each radio in
a MLO group and allow subsequent radios to use different available scan
links (ahvif->link[15..MAX_SCAN_LINKS]) when scan link (15) is
pre-occupied.
While at it, rename ATH12K_DEFAULT_SCAN_LINK as ATH12K_FIRST_SCAN_LINK
as there is no longer only one scan link.

In MLO configuration, ath12k_mac_radio_start() iterates through all
the radios and makes the ar state 'ON'. Even though some bands are
not supported in certain countries, ath12k_reg_update_chan_list()
tries to update the channel list for all the active pdevs and ends
up in the warn_on for non-supported band.
To prevent this, disable the pdev when the number of channels across
all bands supported by the pdev is zero for a particular country.

During beacon miss handling, ath12k driver iterates over active virtual
interfaces (vifs) and attempts to access the radio object (ar) via
arvif->deflink->ar.
However, after commit aa80f12f3bed ("wifi: ath12k: defer vdev creation for
MLO"), arvif is linked to a radio only after vdev creation, typically when
a channel is assigned or a scan is requested.
For P2P capable devices, a default P2P interface is created by
wpa_supplicant along with regular station interfaces, these serve as dummy
interfaces for P2P-capable stations, lack an associated netdev and initiate
frequent scans to discover neighbor p2p devices. When a scan is initiated
on such P2P vifs, driver selects destination radio (ar) based on scan
frequency, creates a scan vdev, and attaches arvif to the radio. Once the
scan completes or is aborted, the scan vdev is deleted, detaching arvif
from the radio and leaving arvif->ar uninitialized.
While handling beacon miss for station interfaces, P2P interface is also
encountered in the vif iteration and ath12k_mac_handle_beacon_miss_iter()
tries to dereference the uninitialized arvif->deflink->ar.
Fix this by verifying that vdev is created for the arvif before accessing
its ar during beacon miss handling and similar vif iterator callbacks.

For WMI_REQUEST_VDEV_STAT request, firmware might split response into
multiple events dut to buffer limit, hence currently in
ath12k_wmi_fw_stats_process() host waits until all events received. In
case there is no vdev started, this results in that below condition
would never get satisfied
((++ar->fw_stats.num_vdev_recvd) == total_vdevs_started)
consequently the requestor would be blocked until time out.
The same applies to WMI_REQUEST_BCN_STAT request as well due to:
((++ar->fw_stats.num_bcn_recvd) == ar->num_started_vdevs)
Change to check the number of started vdev first: if it is zero, finish
directly; if not, follow the old way.

Currently ath12k_wmi_fw_stats_process() is using static variables to count
firmware stat events. Taking num_vdev as an example, if for whatever
reason (say ar->num_started_vdevs is 0 or firmware bug etc.) the following
condition
(++num_vdev) == total_vdevs_started
is not met, is_end is not set thus num_vdev won't be cleared. Next time
when firmware stats is requested again, even if everything is working
fine, failure is expected due to the condition above will never be
satisfied.
The same applies to num_bcn as well.
Change to use non-static counters and reset them each time before firmware
stats is requested.

Regarding the firmware stats events handling, the comment in
ath12k_mac_get_fw_stats() says host determines whether all events have been
received based on 'end' tag in TLV. This is wrong as there is no such tag
at all, actually host makes the decision totally by itself based on the
stats type and active pdev/vdev counts etc.
Fix it to correctly reflect the logic.

In case of ML connection, currently all useful links are activated at
ASSOC stage:
ieee80211_set_active_links(vif, ieee80211_vif_usable_links(vif))
this results in firmware crash when the number of links activated on the
same device is more than supported.
Since firmware supports activating at most 2 links for a ML connection,
to avoid firmware crash, host needs to select 2 links out of the useful
links. As the assoc link has already been chosen, the question becomes
how to determine partner links. A straightforward principle applied
here is that the resulted combination should achieve the best throughput.
For that purpose, ideally various factors like bandwidth, RSSI etc should
be considered. But that would be too complicate. To make it easy, the
choice is to only take hardware modes into consideration.
The SBS (single band simultaneously) mode frequency range covers 5 GHz
and 6 GHz bands. In this mode, the two individual MACs are both active,
with one working on 5g-high band and the other on 5g-low band (from
hardware perspective 5 GHz and 6 GHz bands are referred to as a 'large'
single 5 GHz band). The DBS (dual band simultaneously) mode covers 2 GHz
band and the 'large' 5 GHz band, with one MAC working on 2 GHz band and
the other working on 5 GHz band or 6 GHz band. Since 5,6 GHz bands could
provide higher bandwidth than 2 GHz band, the preference is given to SBS
mode. Other hardware modes results in only one working MAC at any given
time, so it is chosen only when both SBS are DBS are not possible.
For each hardware mode, if there are more than one partner candidate,
just choose the first one.
For now only single device MLO case is handled as it is easy. Other cases
could be addressed in the future.

In case of two links established on the same device in an ML connection,
depending on device's hardware mode capability, it is possible that both
links fall on the same MAC. Currently, no specific action is taken to
address this but just keep both links active. However this would result
in lower throughput compared to even one link, because switching between
these two links on the resulted MAC significantly impacts throughput.
Check if both links fall in the frequency range of a single MAC. If
so, send WMI_MLO_LINK_SET_ACTIVE_CMDID command to firmware such that
firmware can deactivate one of them. Note the decision of which link
getting deactivated is made by firmware, host only sends the vdev
lists.

Previous patches parse and save hardware MAC frequency range information
in ath12k_svc_ext_info structure. Such range represents hardware
capability hence needs to be updated based on host information, e.g. guard
the range based on host's low/high boundary.
So update frequency range. The updated range is saved in
ath12k_hw_mode_info structure and would be used when doing vdev activation
and link selection in following patches.

WMI_SERVICE_READY_EXT_EVENTID event for later use
WLAN hardware might support various hardware modes such as DBS (dual
band simultaneously), SBS (single band simultaneously) and DBS_OR_SBS
etc, see enum wmi_host_hw_mode_config_type. Firmware advertises actual
supported modes in WMI_SERVICE_READY_EXT_EVENTID event. For each mode,
firmware advertises frequency range each hardware MAC can operate on.
In MLO case such information is necessary during vdev activation and
link selection (which is done in following patches), so add a new
structure ath12k_svc_ext_info to ath12k_wmi_base, then parse and save
those information to it for later use.

When the ath12k driver is built without CONFIG_ATH12K_DEBUG, the
recently refactored stats code can cause any user space application
(such at NetworkManager) to consume 100% CPU for 3 seconds, every time
stats are read.
Commit 'b8a0d83fe4c7 ("wifi: ath12k: move firmware stats out of
debugfs")' moved ath12k_debugfs_fw_stats_request() out of debugfs, by
merging the additional logic into ath12k_mac_get_fw_stats().
Among the added responsibility of ath12k_mac_get_fw_stats() was the
busy-wait for `fw_stats_done`.
Signalling of `fw_stats_done` happens when one of the
WMI_REQUEST_PDEV_STAT, WMI_REQUEST_VDEV_STAT, and WMI_REQUEST_BCN_STAT
messages are received, but the handling of the latter two commands remained
in the debugfs code. As `fw_stats_done` isn't signalled, the calling
processes will spin until the timeout (3 seconds) is reached.
Moving the handling of these two additional responses out of debugfs
resolves the issue.
