Resolve several conflicts, mostly between changes/fixes in
wireless and the locking rework in wireless-next. One of
the conflicts actually shows a bug in wireless that we'll
want to fix separately.

Since '!(0x5ea42b & 0xffff0000)' is always false, remove unreachable

We add TX power table format for Wi-Fi 7 chips. Since Wi-Fi 7 tables are
larger, in order to reuse some chunks, we extend code to process nested
entries. Now, dbgfs txpwr_table can work with Wi-Fi 7 chips.
An output example of dbgfs txpwr_table on Wi-Fi 7 chips is shown below.

We have a register to control TX power of each rate section to increase
or decrease an offset. But, Wi-Fi 6 chips and Wi-Fi 7 chips have different

There are two difference between Wi-Fi 6 and Wi-Fi 7 chips.
1. Address range of TX power control register
2. Checking code to get a TX power control register
So, separate the implementation of them, access according to
chip generation, and rename original things with a suffix `_ax`.

MCC (multi-channel concurrency) supports two combinations as below.
* P2P-GO + STA
* P2P-GC + STA
We add the corresponding ieee80211_iface_limit for it into
ieee80211_iface_combination.
Besides, for multiple channels, it must run with mac80211 chanctx.
So, only with it, ieee80211_iface_combination can allow MCC case.

During (TDMA-based) MCC (multi-channel concurrency), the below two
cases might not have a good behavior on channel usage.
* ROC (remain on channel)
* HW scan
So, we tend to separate them from MCC.
The two cases would expect to operate the channel to which they want.
However, during MCC, channels are scheduled by FW MCC state mechanism.
So, channels cannot be controlled explicitly. To avoid the two cases
from operating wrong channels with chance, we pause MCC (essentially
stop FW MCC) once the two cases are coming. And then, we proceed MCC
again (essentially restart FW MCC) once the two cases finish.

Under TDMA-based MCC (multi-channel concurrency), there are two roles,
reference and auxiliary. We arrange MCC timeline based on time domain
of reference role. Then, we calculate NoA start time according to MCC
timeline.
Besides, when MCC runs GO+STA mode, we plan an offset between GO time
domain and STA time domain to make their TBTTs have a time gap.
However, if GO is auxiliary role instead of reference role, NoA start
time is described by STA time domain instead of GO time domain. To fix
this, we apply the offset mentioned above to NoA start time to convert
time domain from STA to GO.

Commit e8c1841278a7 ("wifi: cfg80211: annotate iftype_data pointer with

which immediately found an issue in ath11k:
drivers/net/wireless/ath/ath11k/mac.c:7952:22: warning: incorrect type in argument 1 (different address spaces)

drivers/net/wireless/ath/ath11k/mac.c:7952:22: got struct ieee80211_sta_he_cap const [noderef] __iftype_data *
The problem here is that we are accessing sband->iftype_data directly even
though we should use for_each_sband_iftype_data() or similar. Fortunately
there's ieee80211_get_he_iftype_cap_vif() which is just what we need here so
use it to get HE capabilities.

WCN7850 and QCN9274 currently use the same structure rx_msdu_end_qcn9274
for msdu_end. But content of msdu_end on WCN7850 is different from that of
QCN9274. Need to update it for WCN7850, otherwise will get the wrong
values when using it.
For example, TID is no longer in WCN7850's msdu_end. But
ath12k_dp_rx_process_err() and ath12k_dp_rx_process_wbm_err() still get
TID from msdu_end. So an uncertain value will be used in these two
functions on WCN7850.
Therefore, add new structure rx_msdu_end_wcn7850 for WCN7850.

BSS_CHANGED_UNSOL_BCAST_PROBE_RESP if there are no updates to
FILS discovery and unsolicited broadcast probe response transmission
configurations respectively. For BSS change operations such as channel
switch, this results in the transmissions getting stopped because the

Remove the checks for the flags to always send the existing

Currently mac80211 will send 3 scan request for each scan of WCN7850, they
are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN7850 will cache the RNR
IE(Reduced Neighbor Report element) which exist in the beacon of 2.4 GHz/5
GHz of the AP which is co-located with 6 GHz, and then use the cache to
scan in 6 GHz band scan if the 6 GHz scan is in the same scan with the 2.4
GHz/5 GHz band, this will helpful to search more AP of 6 GHz. Also it will
decrease the time cost of scan because firmware will use dual-band scan
for the 2.4 GHz/5 GHz, it means the 2.4 GHz and 5 GHz scans are doing
simultaneously.
Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 since it
supports 2.4 GHz/5 GHz/6 GHz in a single wiphy/ieee80211_hw.
This does not impact QCN9274, because it is not single_phy, so does not
have 2.4 GHz/5 GHz/6 GHz in the same wiphy, then it does not match the
condition and then IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS will not set for
QCN9274.

ath12k prints "Received scan event for unknown vdev" when doing the
following test:
1. trigger scan
2. wait 0.2 second
3. iw reg set is issued or 11d scan complete event is sent from firmware
Reason is:
When iw reg set is issues or the 11d scan complete event is received, the
new country code will be set to the firmware, and the new regdomain info
indicated to ath12k, then the new channel list will be sent to the firmware.
The firmware will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID
which is used for the new channel list, and the state of ath12k is
ATH12K_SCAN_RUNNING, then ath12k_get_ar_on_scan_abort() returns NULL and
ath12k_scan_event() returns at this point and does not indicate scan
completion to mac80211.
Indicate scan completion to mac80211 and get rid of the "Received scan
event for unknown vdev" print for the above case.

ATH12K_SCAN_STARTING state
Scan failure can not be recovered from when running a loop of the
following steps:
1. run scan: "iw wlan scan".
2. run command: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0/simulate_fw_crash
immediately after step 1.
result:
scan failed and can not recover even when wlan recovery succeeds:
command failed: Device or resource busy (-16)
reason:
When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and
function ath12k_mac_op_hw_scan() returns, then simulate_fw_crash arrives
and the scan started event does not arrive, and then it starts to do
recovery of wlan. __ath12k_mac_scan_finish() which is called from
ath12k_core_halt() is one step of recovery, it will not call
ieee80211_scan_completed() by logic currently because the scan state is
ATH12K_SCAN_STARTING. Thus it leads the scan not being completed in
mac80211, and leads all consecutive scans failing with -EBUSY in
nl80211_trigger_scan even after wlan recovery success.
Indicate scan complete with aborted flag to mac80211 for
ATH12K_SCAN_STARTING to allow recovery from scan failed with "Device or
resource busy (-16)" after wlan recovery.

When firmware crashed while channel switch running, recovery starts in
ath12k. Then ieee80211_sta_connection_lost() will be called by function
ieee80211_restart_work() in mac80211. And then many WMI command timeout
because firmware is crashed. Each WMI command cost 3 seconds, then the
total time will be large and leads recovery fail.
Hence change to set value ATH12K_FLAG_CRASH_FLUSH early and then
ath12k_wmi_cmd_send() will not wait 3 seconds, then recovery will be
started quickly and success.

When hardware rfkill is enabled in the firmware, it will report the
capability using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event
to the host. Currently ath12k does not process this service capability. In
order to support this, update ath12k to check if the capability is enabled,
if so, send the GPIO information to firmware. When the firmware detects
hardware rfkill is enabled by the user, it will report it using
WMI_RFKILL_STATE_CHANGE_EVENTID. When ath12k receive the event, it will set
the value of rfkill_radio_on based on whether radio_state is equal to
WMI_RFKILL_RADIO_STATE_ON, then send WMI_PDEV_PARAM_RFKILL_ENABLE to
firmware.

If we just check "result & RX_DROP_UNUSABLE", this really only works
by accident, because SKB_DROP_REASON_SUBSYS_MAC80211_UNUSABLE got to
have the value 1, and SKB_DROP_REASON_SUBSYS_MAC80211_MONITOR is 2.
Fix this to really check the entire subsys mask for the value, so it
doesn't matter what the subsystem value is.

If the structure is not initialized then boolean types might be copied
into the tracing data without being initialised. This causes data from
the stack to leak into the trace and also triggers a UBSAN failure which
can easily be avoided here.
