Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() uses
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
Explicitly add the WQ_UNBOUND flag to alloc_workqueue() users, marking
the workqueue unbound.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.

Marvell/NXP Wi-Fi adapters allow fine-grained adjustment of the transmit
power levels and various other internal parameters. This is done by
sending command streams to the adapter. One storage format of these
command streams are the rgpower tables, which consist of multiple
command blocks in the following format:
command_block_1 = {
XX XX LL LL XX XX ..
}
command_block_n = {
XX XX LL LL XX XX XX ..
}
XX = raw byte as hex chars
LL = total length of the "raw" command block
These command blocks are parsed into their binary representation and
then send to the adapter. The parsing logic was adapted from NXP's
mwifiex driver[1].
The rgpower tables matching the currently set regulatory domain are
automatically requested and applied. If not found the existing device
tree provided power tables are tried as well.

The adapter->chan_stats[] array is initialized in
mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
memory. The array is filled in mwifiex_update_chan_statistics()
and then the user can query the data in mwifiex_cfg80211_dump_survey().
There are two potential issues here. What if the user calls
mwifiex_cfg80211_dump_survey() before the data has been filled in.
Also the mwifiex_update_chan_statistics() function doesn't necessarily
initialize the whole array. Since the array was not initialized at
the start that could result in an information leak.
Also this array is pretty small. It's a maximum of 900 bytes so it's
more appropriate to use kcalloc() instead vmalloc().

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

This reverts commit 4fcfcbe457 ("wifi: mwifiex: Fix HT40 bandwidth

That commit introduces a regression, when HT40 mode is enabled,
received packets are lost, this was experience with W8997 with both
SDIO-UART and SDIO-SDIO variants. From an initial investigation the
issue solves on its own after some time, but it's not clear what is
the reason. Given that this was just a performance optimization, let's
revert it till we have a better understanding of the issue and a proper
fix.

Historically all commands sent to the mwifiex driver have been
asynchronous. The different commands sent during driver initialization
have been queued at once and only the final command has been waited
for being ready before finally starting the driver.
This has been changed in Commit 7bff9c974e ("mwifiex: send firmware
initialization commands synchronously"). With this the initialization
is finished once the last mwifiex_send_cmd_sync() (now
mwifiex_send_cmd()) has returned. This makes all the code used to
wait for the last initialization command to be finished unnecessary,
so it's removed in this patch.

mwifiex_sta_init_cmd() returns -EINPROGRESS as success indication when
the init param is true. Likewise mwifiex_init_fw() returns -EINPROGRESS
as success indication: It will either return -EINPROGRESS directly when
in mfg_mode or the return value of mwifiex_sta_init_cmd() when in normal
mode.
-EINPROGRESS is a leftover from times when the initialization commands
were sent asynchronously. Since Commit 7bff9c974e ("mwifiex: send
firmware initialization commands synchronously") the return value has
become meaningless, so change mwifiex_sta_init_cmd() and
mwifiex_init_fw() to return 0 for success.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

In mwifiex_add_virtual_intf() several settings done in a switch/case
are the same in all cases. Move them out of the switch/case to
deduplicate the code.
bss_started is not initialized in all switch/case branches, but it is
only used in AP mode in the driver, so it doesn't hurt to move its
initialization out of the switch/case as well.

In mwifiex_setup_ht_caps() first a local struct ieee80211_mcs_info
is initialized and afterwards copied over &ht_info->mcs. Simplify
this by initializing &ht_info->mcs directly.
While at it call memset on the u8 rx_mask[] array instead of the struct
which makes the intention clearer and we no longer have to assume the
rx_mask array is the first member of struct ieee80211_mcs_info.

Jason mentioned at netdevconf that we've run out of tx_flags in
the skb_shinfo(). Gain one bit back by removing the wifi bit.
We can do that because the only userspace application for it
(hostapd) doesn't change the setting on the socket, it just
uses different sockets, and normally doesn't even use this any
more, sending the frames over nl80211 instead.

This patch resolves an issue where RF calibration data from a
file could not be downloaded to the firmware. The feature to
download calibration data from a file was broken by the commit:
d39fbc8895.
The issue arose because the function `mwifiex_cmd_cfg_data()`
was modified in a way that prevented proper handling of
file-based calibration data. While this patch restores the ability
to download RF calibration data from a file, it may inadvertently
break the feature to download calibration data from the device
tree. This is because the function `mwifiex_dnld_dt_cfgdata()`,
which also relies on `mwifiex_cmd_cfg_data()`, is still used for
device tree-based calibration data downloads.

When a character array without a terminating NUL character has a static
initializer, GCC 15's -Wunterminated-string-initialization will only
warn if the array lacks the "nonstring" attribute[1]. Mark the arrays
with __nonstring to and correctly identify the char array as "not a C
string" and thereby eliminate the warning.

With the recent removal of the uncalled
lbs_(enter|exit)_auto_deep_sleep()
functions, it's no longer possible to set
priv->is_auto_deep_sleep_enabled
so we can remove all tests of it and the variable itself.
With that gone, priv->wakeup_dev_required also doesn't
get set, so we can remove any testing of it.
Now the timer itself, and the function it calls goes.
The timer used the apparently unset auto_deep_sleep_timeout
member, which can also go.

In commit 52250cbee7 ("mwifiex: use timeout variant for
wait_event_interruptible") it was noted that sometimes we seemed
to miss the signal that our host sleep settings took effect. A
10 second timeout was added to the code to make sure we didn't
hang forever waiting. It appears that this problem still exists
and we hit the timeout sometimes for Chromebooks in the field.
Recently on ChromeOS we've started setting the DPM watchdog
to trip if full system suspend takes over 10 seconds. Given
the timeout in the original patch, obviously we're hitting
the DPM watchdog before mwifiex gets a chance to timeout.
While we could increase the DPM watchdog in ChromeOS to avoid
this problem, it's probably better to simply decrease the
timeout. Any time we're waiting several seconds for the
firmware to respond it's likely that the firmware won't ever
respond. With that in mind, decrease the timeout in mwifiex
from 10 seconds to 5 seconds.

Currently, TX power is reported on interface/wdev level as
part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links
can be part of an interface/wdev and hence its necessary to
report the TX power of each link.
Add support to send tx power for all valid links of an MLD as
part of NL80211_CMD_GET_INTERFACE request.
As far as userspace is concerned, there is no behavioral change
for Non-ML Interfaces. For ML interfaces, userspace should fetch
TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to
how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.
