As Hash based reo destination selection is configured,
the decapped packets reach different reo destintion rings
based on the destintaion ring selected for the computed hash (based on
the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and
as configured by driver.
Hence the current implementation of amsdu list based processing after all
the subframes of amsdu are received (since all msdu's for a pdev are
received in same reo dest ring), is not applicable here and hence is
replaced with per msdu based handling as these subframes
can be received in different reo dest rings.
Also, as some of the rx descriptor fields might be valid only for the
first msdu (for ex. received 80211 header, encryption type, etc),
it might not be useful now as we cannot sync between different
subframes received in different rings. Hence do not rely on those
fields and replace them with fieds valid only on per msdu descriptors.
Also cache other details such as encryption type for a peer so that
it can be reused when a packet is received from it.

Current implementation of pdev based reo destination ring
selection is replaced by hash based ring selection so as to
ensure all the available rings are utilized for better performance.
The 4 reo destination rings are selected by the HW based on the
hash value computed from the received packet based on the 5 tuple
{ip src/ip dst/src port/dst port/protocol}. Out of the 32 hash values
used by the hw, the driver assigns 8 values per reo destination ring
to each of the 4 reo destination rings.

Before dumping tx_stats proper validation was not been taken care of.
Due to which we were encountering null pointer dereference(kernel panic).
This scenario will arise when a station is getting disconnected and
we are changing the STA state by ath11k_mac_op_sta_state and assigning
tx_stats as NULL and after this the mac80211 will destroy the
debugfs entry from where we are trying to read the stats.
If anyone tries to dump tx_stats for that STA in between setting
tx_stats to NULL and debugfs file removal without checking the NULL
value it will run into a NULL pointer exception.
Proceeding with the analysis of "ARM Kernel Panic".
The APSS crash happened due to OOPS on CPU 3.
Crash Signature : Unable to handle kernel NULL pointer dereference at
virtual address 00000360
During the crash,

Enabling PN checking in the hardware; hardware checks
the PN of the received packets and reports the errors
to the host for further handling; default action is to
drop such packets. TSC (TKIP sequence counter)
validation is also offloaded.
Hardware validates PN/TSC only for unicast packets;
for group addressed packets, PN validation is done
in mac80211.
PN errors are reported to the driver via WBM RX release
ring and can be dumped by using the following command.
"cat /sys/kernel/debug/ath11k/soc_rx_stats | grep -i pn"
Sample Output:
PN check fail: 210

IPQ8074 HW has support to verify the PN of the received frames.
For all frames except for fragmented ones, HW checks the PN and
delivers them to the driver. For fragmented frames, driver is
required to do a little more; it has to reassemble the fragments
and then reinject them to the HW for verifying the PN. Currently,
to keep the logic simple, PN verifcation is disabled in HW and is
handled in mac80211 for all the frames (fragmented and unfragmented).
On the contrary, offloading PN Validation to the HW brings important
benefits. It reduces CPU cycles spent on the host CPU for verifying
the same; helps in enabling features which improve performance like
mac80211 fast RX path, enabling multiple REO rings for parallel RX
processing, 802.11 decapsulation offloading. All these features are
dependent on PN offload which in turn is dependent on handling of
the received fragments in the driver.
When TKIP security is used, additional handling is required while
processing the fragments; since MIC is computed on an MSDU in TKIP,
only the last fragment has the MIC info. In this case, driver has to
compute the MIC after reassembly and compare it against the MIC
present in the frame. For this, MICHAEL_MIC kernel crypto library
APIs are used and the dependencies are appropriately set.

When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.
This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:
ieee80211_do_open()
ath9k_add_interface()
ath9k_set_txpower() /* Set TX power with not yet initialized
sc->hw->conf.power_level */
ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
raise IEEE80211_CONF_CHANGE_POWER */
ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */
This issue can be reproduced with the following:
$ modprobe -r ath9k
$ modprobe ath9k
$ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
$ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
$ killall wpa_supplicant
$ iw dev /* TX power goes back to calibrated value and subsequent
calls will be fine */

MMPDU capbility is not supported. Then 11a station's airtime will

Currently rx tid setup is happening for TID 0 and TID 16
during peer setup. And if other TID packets received for
the peer it will be redirected to rx error ring and not through
reo ring. And this rx tid configuration cannot be done
in the rx error ring path since it is a atomic context.
So moving the rx tid setup for all tids during the peer setup.
This is required to enable PN offload functionality to route
all packets through reo ring.

Before this change, after writing "warm_hw_reset" debugfs file, host
will send chip reset command to FW even though FW do not support this
service getting a warning print.
Though there is no FW impact before this change, this patch restricts
chip reset command sent to FW only if FW advertises the support via WMI
service bit.
Removed the redundant check and ath10k_warn() print as well.
New version FW will report chip reset service bit to host. Host allow user
to trigger WLAN chip reset only when fw report this service bit.
For older NON-TLV FW, since it do not report chip reset service bit, host
will not send chip reset command. For older TLV FW, since it report chip
reset service bit, host will send chip reset command.

For sdio chip, it need the memory which is kmalloc, if it is
vmalloc from ath10k_mem_value_read, then it have a memory error.
kzalloc of ath10k_sdio_hif_diag_read32 is the correct type, so
add kzalloc in ath10k_sdio_hif_diag_read to replace the buffer
which is vmalloc from ath10k_mem_value_read.

Currently, OTP is downloaded twice in case of "pre-cal-dt"
and "pre-cal-file" to fetch the board ID and takes around
~2 sec more boot uptime.
First OTP download happens in "ath10k_core_probe_fw" and
second in ath10k_core_start. First boot does not need OTP
download in core start when valid board id acquired.
The second OTP download is required upon core stop/start.
This patch skips the OTP download when first OTP download
has acquired a valid board id. This patch also marks board
id invalid in "ath10k_core_stop", which will force the OTP
download in ath10k_core_start and fetches valid board id.

A few big new things:
* 802.11 frame encapsulation offload support
* more HE (802.11ax) support, including some for 6 GHz band
* powersave in hwsim, for better testing
Of course as usual there are various cleanups and small fixes.

With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.
If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.
ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.
So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.
This should fix regression in:

In multi AP VAP scenario, when user bring down the interfaces. mac80211 mark
the interface down for the duplicated VAP and removed from the
local->interfaces list. ath11k_mac_get_arvif() is dependent on
ieee80211_iterate_active_interfaces_atomic() API to find the vdev id
in a given radio. In disassociation path, ath11k_mac_get_arvif() not
able to find the given vdev id since that VAP is removed from the
local->interfaces list. since sta_state callback throws error, mac80211 log
the below WARN_ON_ONCE message.
Fixed it by storing the allocated_vdev_map in each radio structure to maintain
the created vdev id bits. so that we can directly mask this against the given
vdev_id to find out the ar from the vdev_id.

ath11k_update_per_peer_stats_from_txcompl
Clang warns a few times (trimmed for brevity):
../drivers/net/wireless/ath/ath11k/debugfs_sta.c:185:7: warning:
variable 'rate_idx' is used uninitialized whenever 'if' condition is
false [-Wsometimes-uninitialized]
It is not wrong, rate_idx is only initialized in the first if block.
However, this is not necessarily an issue in practice because rate_idx
will only be used when initialized because
ath11k_accumulate_per_peer_tx_stats only uses rate_idx when flags is not
set to RATE_INFO_FLAGS_HE_MCS, RATE_INFO_FLAGS_VHT_MCS, or
RATE_INFO_FLAGS_MCS. Still, it is not good to stick uninitialized values
into another function so initialize it to zero to prevent any issues
down the line.

BTCOEX feature is not supported by all QCA4019 chipsets.
Since btcoex enabled by default in firmware, host needs to

by default in unsupported hardware will cause some
feature disabled in hardware.
This patch will read btcoex_support flag and
