f40a307eb9 ath10k: Fill rx duration for each peer in fw_stats for WCN3990
Currently, rx_duration for each peer is not getting populated in
fw_stats debugfs entry for WCN3990.

WCN3990 firmware sends rx duration for each peer as part of
peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats,
firmware expects host to send fw_stats_req_mask with flag
WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD.

Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in
WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in
WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer
in fw_stats debugfs entry.

Currently the driver handles 32-bit rx_duration, but the rx_duration
for WCN3990 can be upto 63 bit. The firmware sends rx_duration split
into two 32-bit fields, with the upper 32-bits being valid only if its
MSB is set. This change handles the 63-bit rx_duration obtained from
WCN3990 and maintain the backward compatibility.

To get the rx_duration of each connected peer :
cat /sys/kernel/debug/ieee80211/phyX/ath10k/fw_stats

d23c2cdaa0 ath10k: Fix the wrong calculation ht_idx and idx of rate table for tx_stats
ht_idx (ht rate index) and idx (rate table index) are calculated based on
mcs index. This mcs index used in the above calculation should be 0-9 for
getting the correct ht_idx and idx.

Currently the mcs index used for the above calculations is mcs index which
can be 0-31 (in case of HT), leading to incorrect rate index and ht index values.

Fix the issue by obtaining mcs value from the ratecode reported by firmware
and use it for calculating ht_idx and idx (rate-table index).

ef9051c72a ath10k: Fix the wrong updation of BW in tx_stats debugfs entry
Currently, the bandwidth is updated wrongly in BW table in tx_stats
debugfs per sta as there is difference in number of bandwidth type

updated at wrong index in bandwidth table in tx_stats.

02f73d3a9b ath10k: fix descriptor size in ce tx completion for WCN3990
When the driver receives the tx completion of the
descriptor over ce, it clears the nbytes configured

descriptors with 64-bit address.

Currently during handling the tx completion of the
descriptors, the nbytes are accessed from the descriptors
using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater
than 32 bits.

Attach different ce tx copy completed handler for targets

Three conflicts, one of which, for marvell10g.c is non-trivial and

The issue is that Heiner converted the marvell10g driver over to

714afd3506 iwlwifi: remove redundant condition from prior alive dump flow
After the FW image was loaded for the first time,
fwrt->smem_cfg.num_lmacs value will no longer be zero since we don't
clean it when we stop the device. So if we load the image once and then
we fail on a consecutive attempt, the driver will abort any dumping.

Solve this by removing the condition. It is safe to remove since
when we do the actual dumping in iwl_fw_dbg_collect_sync we check
that STATUS_DEVICE_ENABLED bit is still active.

For non-offloaded rate control, implement VHT extended NSS
support by just ignoring 160 MHz on transmit if the peer
doesn't support the full NSS (2). This is pretty unlikely
and gets us 160 MHz RX as well as TX in most cases, since
the typical case for this workaround is 4x4 AP only doing
2x2 on 160 MHz.

8c739d8d79 iwlwifi: mvm: Allow retries for probe responses
When hostapd sends a probe response, it does not request an
acknowledgment on the probe response. This setting is propagated
to the driver and FW from mac80211, and as a result probe responses
are transmitted only once without retries. In congested
environments, this reduces the likelihood for finding the AP.

To overcome this, enable acknowledgment and retries for probe
responses, even in case no acknowledgment is requested. In such
a case the retry limit is set to 3.

We support this, so we should advertise it. In fact, if we don't,
mac80211 will do it for us (as we advertise SUPPORTS_VHT_EXT_NSS_BW
to it), but that requires a memory reallocation which is wasteful:

6b367c9f88 iwlwifi: nvm-parse: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

baa0280f08 libertas_tf: don't defer firmware loading until start()
In order to be able to get a MAC address before we register the device
with ieee80211 we'll need to load the firmware way earlier.

There seems to be one problem with this: the device seems to start
with radio enabled and starts sending in frames right after the firmware
load finishes. Disable the radio as soon as possible.

on a firmware that doesn't have ad-hoc support just yields failures of
HostCmd_CMD_SET_BSS_MODE, which happened to return a '-1' error code
(-EPERM? not really right...) and sometimes may even crash the firmware
along the way.

Let's parse the firmware capability flag while registering the wiphy, so
we don't allow attempting IBSS at all, and we get a proper -EOPNOTSUPP

16e6467683 brcmfmac: rework bphy_err() to take struct brcmf_pub argument
This macro will be used in more places not just the cfg80211.c. It makes
sense to pass some common struct to it as "struct wiphy" is mostly
referenced in cfg80211 code only.

A very common one (used above the bus abstraction layer) is struct
brcmf_pub. Many functions already keep reference to it which will make
using bphy_err() simpler. It should also allow extending that macro's
logic if it's ever needed.

This improves code recently added in the commit 3ef005b82e ("brcmfmac:

aaf6a5e86e brcmfmac: create debugfs files for bus-specific layer
Since we moved the drivers debugfs directory under ieee80211 debugfs the
debugfs entries need to be added after wiphy_register() has been called.
For most part that has been done accordingly, but for the debugfs entries
added by SDIO it was not and failed silently. This patch fixes that by
adding a bus-layer callback for it.

a4176ec356 brcmfmac: add subtype check for event handling in data path
For USB there is no separate channel being used to pass events
from firmware to the host driver and as such are passed over the
data path. In order to detect mock event messages an additional
check is needed on event subtype. This check is added conditionally
using unlikely() keyword.

2 STA vifs) and more related with MAC address, so initaize BSSID when
setting MAC address.

99944b7306 iwlwifi: mvm: stop static queues correctly
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

44135b7c53 iwlwifi: mvm: Do not return an error value on HW restart
When HW restart is requested but not started yet, commands would not
be sent to the FW, and some function calls would return an error. In
case of iwl_mvm_mac_sta_state() returning an error value when a
station is removed can lead to an unneeded warning in
__sta_info_destroy_part2().

Handle this by setting the return value to 0, in case HW restart is
in progress.

69e508b44d iwlwifi: mvm: Don't warn on command failure during restart
When HW restart is requested but not started yet, commands would not
be sent to the FW, and some function calls return an error. Such cases
can trigger unneeded warning messages, e.g., in iwl_mvm_mac_sta_state()
and iwl_mvm_bss_info_changed_station().

Handle a couple of these cases by also checking in the WARN_ON()
condition that HW restart is not requested.

21587a9b0a iwlwifi: dbg: buffer overflow in non_collect_ts_start array
The size of the buffer is IWL_FW_TRIGGER_ID_NUM - 1 which is equal to
IWL_FW_TRIGGER_ID_HOST_CHANNEL_SWITCH_COMPLETE so if the driver receives
this trigger, it will cause a buffer overflow.

Solve this by increasing the buffer size by 1.

The spatial reuse 4 words fields are fetched from the HE-SIGA

Rx info. This is useful to populate the radiotap header.

We were looking at the wrong place in the firmware data and

Fix several issues related to dump delay:
1. In legacy dump trigger, use stop_delay field instead of trig_dis_ms.
2. ini delay is messured in usec so align both ini and legacy to usec.
3. schedule_delayed_work receives the delay value in jiffies so
translate the dump delay to jiffies.
