The napi_gro_receive function no longer returns GRO_DROP ever, making
handling GRO_DROP dead code. This commit removes that dead code.
Further, it's not even clear that device drivers have any business in
taking action after passing off received packets; that's arguably out of
their hands. In this case, too, the non-gro path didn't bother checking
the return value. Plus, this had some clunky debugging functions that
duplicated code from elsewhere and was generally pretty messy. So, this
commit cleans that all up too.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

If 'thermal_cooling_device_register()' fails, we must undo what has been
allocated so far. So we must go to 'err_thermal_destroy' instead of
returning directly
In case of error in 'ath11k_thermal_register()', the previous
'thermal_cooling_device_register()' call must also be undone. Move the
'ar->thermal.cdev = cdev' a few lines above in order for this to be done
in 'ath11k_thermal_unregister()' which is called in the error handling
path.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

HTT EXT stats comes in stream of TLVs spanning over multiple
messages. Currently completion is being sent for each message
which is creating a race where stats_req is being accessed
for filling in second message after the memory is already
freed in release operation. Fix this by issuing completion
once all the messages are received and processed. Driver
knows this info from DONE bit set in htt msg.
Also fix locking required for htt stats.

The last addition to the struct ignored the comments and added
new members behind the array that must remain last.
Change it to a flexible-array member and move it last again to
make it work correctly, prevent the same thing from happening
again (all compilers warn about flexible-array members in the
middle of a struct) and get it to build without warnings.

Currently when the sending of any management pkt
via wmi command fails, the packet is being unmapped
freed in the error handling. But the idr entry added,
which is used to track these packet is not getting removed.
Hence, during unload, in wmi cleanup, all the entries
in IDR are removed and the corresponding buffer is
attempted to be freed. This can cause a situation where
one packet is attempted to be freed twice.
Fix this error by rmeoving the msdu from the idr
list when the sending of a management packet over
wmi fails.

The qmi infrastructure sends the client a del_server
event when the client releases its qmi handle. This
is not the msg indicating the actual qmi server exiting.
In such cases the del_server msg should not be processed,
since the wifi firmware does not reset its qmi state.
Hence skip the processing of del_server event when the
driver is unloading.

The driver is not handling monitor status descriptor whenever
the done bit of status descriptor is not set by hardware. This leave
a stale entry in monitor status ring and flooding warning message.
Fix that by removing the descriptor and move forward to next one
in monitor status ring.

Kalle Valo says:
====================
wireless-drivers-next patches for v5.8
First set of patches for v5.8. Changes all over, ath10k apparently
seeing most new features this time. rtw88 also had lots of changes due
to preparation for new hardware support.
In this pull request there's also a new macro to include/linux/iopoll:
read_poll_timeout_atomic(). This is needed by rtw88 for atomic
polling.
Major changes:
ath11k
* add debugfs file for testing ADDBA and DELBA
* add 802.11 encapsulation offload on hardware support
* add htt_peer_stats_reset debugfs file
ath10k
* enable VHT160 and VHT80+80 modes
* enable radar detection in secondary segment
* sdio: disable TX complete indication to improve throughput
* sdio: decrease power consumption
* sdio: add HTT TX bundle support to increase throughput
* sdio: add rx bitrate reporting
ath9k
* improvements to AR9002 calibration logic
carl9170
* remove buggy P2P_GO support

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

Some devices like TP-Link TL-WN722N produces this kind of messages
frequently.
kernel: ath: phy0: Short RX data len, dropping (dlen: 4)
This warning is useful for developers to recognize that the device
(Wi-Fi dongle or USB hub etc) is noisy but not for general users. So
this patch make this warning to debug message.

htt stats are not working after htt peer stats display
and also after htt peer stats reset. Trying to dump htt
stats shows "Resource temporarily unavailable".
This is because of "ar->debug.htt_stats.stats_req" member is being
consecutively used for all htt stats without being reset
during the previous usage. Hence assigning NULL to this member
after freeing the allocated memory fixes the issue.

The struct cfg80211_wowlan of NET_DETECT WoWLAN feature share the same
struct cfg80211_sched_scan_request together with scheduled scan request
feature, and max_sched_scan_reqs of wiphy is only used for sched scan,
and ath10k does not support scheduled scan request feature, so ath10k
does not set flag NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR, but ath10k
set max_sched_scan_reqs of wiphy to a non zero value 1, then function
nl80211_add_commands_unsplit of cfg80211 will set it support command
NL80211_CMD_START_SCHED_SCAN because max_sched_scan_reqs is a non zero
value, but actually ath10k not support it, then it leads a mismatch result
for sched scan of cfg80211, then application shill found the mismatch and
stop running case of MAC random address scan and then the case fail.
After remove max_sched_scan_reqs value, it keeps match for sched scan and
case of MAC random address scan pass.

As the exisiting CE configurations are defined in global, there
are the chances of QCA99X0 family chipsets CE configurations
are getting changed by the ath10k_pci_override_ce_config()
function.
The override will be hit and CE5 configurations will be changed,
when the user bring up the QCA99X0 chipsets along with QCA6174
or QCA9377 chipset. (Bring up QCA99X0 family chipsets after
QCA6174 or QCA9377).
Hence, fixing this issue by moving the global CE configuration
to radio specific CE configuration.
