This isn't used in this driver, and should't be, so
remove the include as well as the select.

This really should never have been used, it's ancient code,
but then the driver needs its own define for NUM_WEP_KEYS.

This driver doesn't use it, and really can't, so don't
include lib80211.h.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct ieee80211_radiotap_header_fixed`.
This structure groups together all the members of the flexible
`struct ieee80211_radiotap_header` except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct ieee80211_radiotap_header` to `struct
ieee80211_radiotap_header_fixed`.
We also want to ensure that in case new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct ieee80211_radiotap_header_fixed`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:

iwl4965 fails upon resume from hibernation on my laptop. The reason
seems to be a stale interrupt which isn't being cleared out before
interrupts are enabled. We end up with a race beween the resume
trying to bring things back up, and the restart work (queued form
the interrupt handler) trying to bring things down. Eventually
the whole thing blows up.
Fix the problem by clearing out any stale interrupts before
interrupts get enabled during resume.
Here's a debug log of the indicent:

Currently, mem_ce and mem iomem addresses are used to calculate the
CE offset address. mem_ce is initialized with mem address, and for
targets where ce_remap is needed, mem_ce is remapped to a new address
space during AHB probe.
For targets such as WCN6750 in which CE address space is same as WCSS
address space (i.e. "ce_remap" hw_param is set to false), mem_ce and
mem iomem addresses are same. In the initial SRNG setup for such targets,
the CE offset address and hence CE register base addresses are
calculated correctly in ath11k_hal_srng_init() as both mem and mem_ce
are initialized with same iomem address.
Later, after the firmware download, mem is initialized with BAR address
received in qmi_wlanfw_device_info_resp_msg_v01 QMI message, while mem_ce
is not updated.
After initial setup success, during Subsystem Restart (SSR), as part
of reinitialization, ath11k_hal_srng_init() will be called again,
and CE offset address will be calculated incorrectly this time as mem_ce
address was not updated. Due to the incorrect CE offset address,
APPS accesses an invalid CE register address which leads to improper
behavior in firmware after SSR is triggered.
To fix the above issue, update mem_ce to mem iomem address in
ath11k_qmi_request_device_info() for targets which do not support
ce_remap feature.

The API print_array_to_buf() currently supports printing
arrays with 0 indexing. In some cases, a few arrays need
to be printed with 1-based indexing, i.e., array should be
printed, starting with 1.
Add a new version of print_array_to_buf(), named
print_array_to_buf_index(), which implements the functionality
of print_array_to_index(), but with an extra variable, pointing
to the index starting with which the array should be printed.
Modify print_array_to_buf() to call
print_array_to_buf_index() with 0 as the starting index.

During ath12k module removal, in ath12k_core_deinit(),
ath12k_mac_destroy() un-registers ah->hw from mac80211 and frees
the ah->hw as well as all the ar's in it. After this
ath12k_core_soc_destroy()-> ath12k_dp_free()-> ath12k_dp_cc_cleanup()
tries to access one of the freed ar's from pending skb.
This is because during mac destroy, driver failed to flush few
data packets, which were accessed later in ath12k_dp_cc_cleanup()
and freed, but using ar from the packet led to this use-after-free.

Commit 24de1b7b231c ("wifi: ath12k: fix flush failure in recovery
scenarios") added the change to decrement the pending packets count
in case of recovery which make sense as ah->hw as well all
ar's in it are intact during recovery, but during core deinit there
is no use in decrementing packets count or waking up the empty waitq
as the module is going to be removed also ar's from pending skb's
can't be used and the packets should just be released back.
To fix this, avoid accessing ar from skb->cb when driver is being
unregistered.

beacons are enabled again with BSS_CHANGED_BEACON_ENABLED.

In range test, the RSSI is helpful to check attenuation of cable and align
difference between environments. Since data packets can be transmitted with
different rate and power, the RSSI of all packets can be variant.
Oppositely beacon is transmitted with the same rate and power, so beacon
RSSI will be relatively invariant, and more helpful to diagnose problems.
The output of beacon RSSI in unit of dBm looks like:
Beacon: 19 (-33 dBm), TF: 0

Those two fields are used to store the per SPT page of tx/rx descriptors send to
the firmware for cookie conversion. Right now they are in struct ath12k_spt_info
which means they are duplicated PPT page times while we only need one instance
of them. This works for now as we always use the first spt_info as a global
storage for all PPT pages.
Let's move them into struct ath12k_dp where they belong, alongside of the
spt_info array they are tied to, to avoid waisting a good bit of memory.

On SC7280 platforms which are running with TrustZone, it is not
necessary to manually map the memory regions used by the wifi hardware.
However, ath11k will currently fail to load unless both memory regions
are specified.
This breaks wifi on the rb3gen2 which only specifies the firmware memory
region and does not use the CE region.
Adjust the order of operations in ath11k_ahb_fw_resources_init() to
check for the wifi-firmware subnode before attempting to parse the
memory regions.

Currently struct ath11k_hal::srng_config pointer is not assigned
to NULL after freeing the memory in ath11k_hal_srng_deinit().
This could lead to double free issue in a scenario where
ath11k_hal_srng_deinit() is invoked back to back.
In the current code, although the chances are very low, the above
said scenario could happen when hardware recovery has failed and
then there is another FW assert where ath11k_hal_srng_deinit() is
invoked once again as part of recovery.
Fix this by assigning the struct ath11k_hal::srng_config pointer
to NULL after freeing the memory.

no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

The drv_priv hooked to mac80211 become as below.
(drv_priv) (instance-0)
+---------------+ +-----------+ +----------------+
| ieee80211_vif | <---> | rtw89_vif | -------> | rtw89_vif_link |
+---------------+ +-----------+ | +----------------+
|
| (instance-1)
| +----------------+
+---> | rtw89_vif_link |
+----------------+
(drv_priv) (instance-0)
+---------------+ +-----------+ +----------------+
| ieee80211_sta | <---> | rtw89_sta | -------> | rtw89_sta_link |
+---------------+ +-----------+ | +----------------+
|
| (instance-1)
| +----------------+
+---> | rtw89_sta_link |
+----------------+
The relation bewteen mac80211 link_id and our link instance is like below.
|\
(link_id) | \
0 -------- | |
1 -------- | | ------ instance-0 (link_id: X) -> work on HW band 0
2 -------- | |
... | | ------ instance-1 (link_id: Y) -> work on HW band 1
14 -------- | |
| /
|/
N.B. For cases of non-MLD connection, we set our link instance-0
active with link_id 0. So, our code flow can be compatible between
non-MLD connection and MLD connection.
Based on above, we tweak entire driver architecture first. But, we don't
dynamically enable multiple links here. That will be handled separately.
Most of the things changed here are changing flows to iterate all active
links and read bss_conf/link_sta data according to target link. And, for
cases of scan, ROC, WOW, we use instance-0 to deal with the request.
There are some things listed below, which work for now but need to extend
before multiple active links.
1. tx path
select suitable link instance among multiple active links
2. rx path
determine rx link by PPDU instead of always link instance-0
3. CAM
apply MLD pairwise key to any active links dynamically
Besides, PS code cannot easily work along with tweaking architecture. With
supporting MLO flag (currently false), we disable PS first and will fix it
by another commit in the following.

Tweak code to not always access sta->deflink directly. Instead,
according to link_id, read target link_sta from sta->link[].
For now, rtwsta_link->link_id keeps 0. When driver starts to

MLO changes, so some functions' namings are not really determined here.
e.g. struct rtw89_sta_link *sta_to_rtwsta_safe(struct ieee80211_sta *sta)
No logic is changed.

When removing kernel modules by:
rmmod rtw88_8723cs rtw88_8703b rtw88_8723x rtw88_sdio rtw88_core
Driver uses skb_queue_purge() to purge TX skb, but not report tx status
causing "Have pending ack frames!" warning. Use ieee80211_purge_tx_queue()
to correct this.
Since ieee80211_purge_tx_queue() doesn't take locks, to prevent racing
between TX work and purge TX queue, flush and destroy TX work in advance.
