5d9e4722c7 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
 
 p54usb
 
 * add support for AirVasT USB stick
 
 rtw88
 
 * add support for antenna configuration

049ceac308 libertas_tf: avoid a null dereference in pointer priv
Currently there is a check if priv is null when calling lbtf_remove_card
but not in a previous call to if_usb_reset_dev that can also dereference
priv.  Fix this by also only calling lbtf_remove_card if priv is null.

It is noteable that there don't seem to be any bugs reported that the
null pointer dereference has ever occurred, so I'm not sure if the null
check is required, but since we're doing a null check anyway it should
be done for both function calls.

14dd3a71cc ath11k: Replace zero-length array with flexible-array
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.

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.

52f274b519 ath11k: fix resource unavailability for htt stats after peer stats display
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.

console logs below:
# echo 9 >/sys/kernel/debug/ath11k/ipq8074/mac1/htt_stats_type

d431f8939c ath10k: remove the max_sched_scan_reqs value
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.

521fc37be3 ath10k: Avoid override CE5 configuration for QCA99X0 chipsets
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.

commit ab92d68fc2
"net: core: add generic lockdep keys"

but keeps the addr_list_lock_key because we still lock
addr_list_lock nestedly on stack devices, unlikely xmit_lock
this is safe because we don't take addr_list_lock on any fast
path.

When calling debugfs functions, there is no need to ever check the

never do something different based on this.

In doing this, make brcmf_debugfs_add_entry() return void as no one was
even paying attention to the return value.

19f557a9b8 brcmfmac: remove arp_hostip_clear from brcmf_netdev_stop
The firmware does not respond ARP request and causes ping failure with
following steps:

1. Bring up interface
   ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
   ifconfig wlan0 192.168.100.10
3. Bring down interface or
   ifconfig wlan0 down or kill wpa_supplicant
4. Bring up interface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.

FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.
Because of that, we remove "arp_hostip_clear" from function
"brcmf_netdev_stop"
