02d31e9b62 iwlwifi: acpi: evaluate dsm to disable 5.8GHz channels
Evaluate the appropriate DSM from ACPI to set ETSI SRD 5.8GHz
channels to passive or disabled, default behaviour is enabled.
Add enums and refactor evaluation of DSM functions for better
readablity and more informative debug prints.

0cd38f4d05 iwlwifi: msix: limit max RX queues for 9000 family
There is an issue in the HW DMA engine in the 9000 family of devices
when more than 6 RX queues are used.  The issue is that the FW may
hang when IWL_MVM_RXQ_NSSN_SYNC notifications are sent.

Fix this by limiting the number of RX queues to 6 in the 9000 family
of devices.

7e0ca7230b iwlwifi: sta: defer ADDBA transmit in case reclaimed SN != next SN
This avoids cases that we have a lot of packets in the queue and until we
are able to transmit SSN packet the other side sends DELBA due to timeout.

44492e70ad rtw88: pci: Power cycle device during shutdown
There are reports that 8822CE fails to work rtw88 with "failed to read DBI
register" error. Also I have a system with 8723DE which freezes the whole
system when the rtw88 is probing the device.

According to [1], platform firmware may not properly power manage the
device during shutdown. I did some expirements and putting the device to
D3 can workaround the issue.

So let's power cycle the device by putting the device to D3 at shutdown
to prevent the issue from happening.

920872e083 net: rtlwifi: Replace in_interrupt() for context detection
rtl_lps_enter() and rtl_lps_leave() are using in_interrupt() to detect
whether it is safe to acquire a mutex or if it is required to defer to a
workqueue.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be seperated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

in_interrupt() also is only partially correct because it fails to chose the
correct code path when just preemption or interrupts are disabled.

Add an argument 'may_block' to both functions and adjust the callers to
pass the context information.

The following call chains were analyzed to be safe to block:

    rtl_watchdog_wq_callback()
      rlf_lps_leave/enter()

    rtl_op_suspend()
      rtl_lps_leave()

    rtl_op_bss_info_changed()
      rtl_lps_leave()

    rtl_op_sw_scan_start()
      rtl_lps_leave()

The following call chains were analyzed to be unsafe to block:

    _rtl_pci_interrupt()
      _rtl_pci_rx_interrupt()
	  rtl_lps_leave()

    _rtl_pci_interrupt()
      _rtl_pci_rx_interrupt()
        rtl_is_special_data()
	  rtl_lps_leave()

    _rtl_pci_interrupt()
      _rtl_pci_rx_interrupt()
        rtl_is_special_data()
	  setup_special_tx()
	    rtl_lps_leave()

    _rtl_pci_interrupt()
      _rtl_pci_tx_isr
        rtl_lps_leave()

      halbtc_leave_lps()
        rtl_lps_leave()

This leaves four callers of rtl_lps_enter/leave() where the analyzis
stopped dead in the maze of several nested pointer based callchains and
lack of rtlwifi hardware to debug this via tracing:

     halbtc_leave_lps(), halbtc_enter_lps(), halbtc_normal_lps(),
     halbtc_pre_normal_lps()

These four have been cautionally marked to be unable to block which is the
safe option, but the rtwifi wizards should be able to clarify that.

e741751bda net: rtlwifi: Remove in_interrupt() from debug macro
The usage of in_interrupt() in drivers in is phased out.

rtl_dbg() a printk based debug aid is using in_interrupt() in the
underlying C function _rtl_dbg_out() which is almost identical to
_rtl_dbg_print(). The only difference is the printout of in_interrupt().

The decoding of in_interrupt() as hexvalue is non-trivial and aside of
being phased out for driver usage the return value is just by chance the
masked preempt count value and not a boolean.

These home brewn printk debug aids are tedious to work with and provide
only minimal context.  They should be replaced by trace_printk() or a debug
tracepoint which automatically records all context information.

To make progress on the in_interrupt() cleanup, make rtl_dbg() use
_rtl_dbg_print() and remove _rtl_dbg_out().

a3b7b227f1 net: rtlwifi: Remove void* casts related to delayed work
INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and
a function reference for the callback.

The rtl code casts all function references to (void *) because the
callbacks in use are not matching the required function signature. That's
error prone and bad pratice.

Some of the callback functions are also global, but only used in a single
file.

Clean the mess up by:

  - Adding the proper arguments to the callback functions and using them in
    the container_of() constructs correctly which removes the hideous
    container_of_dwork_rtl() macro as well.

  - Removing the type cast at the initializers

  - Making the unnecessary global functions static

021b58ef51 net: libertas: Use netif_rx_any_context()
The usage of in_interrupt() in non-core code is phased out. Ideally the
information of the calling context should be passed by the callers or the
functions be split as appropriate.

libertas uses in_interupt() to select the netif_rx*() variant which matches
the calling context. The attempt to consolidate the code by passing an
arguemnt or by distangling it failed due lack of knowledge about this
driver and because the call chains are hard to follow.

As a stop gap use netif_rx_any_context() which invokes the correct code
path depending on context and confines the in_interrupt() usage to core
code.

The debug macro prints (INT) when in_interrupt() returns true. The value of
this information is dubious as it does not distinguish between the various
contexts which are covered by in_interrupt().

As the usage of in_interrupt() in drivers is phased out and the same
information can be more precisely obtained with tracing, remove the

75fd296398 net: hostap: Remove in_interrupt() usage
in_interrupt() is ill defined and does not provide what the name
suggests. The usage especially in driver code is deprecated and a tree wide
effort to clean up and consolidate the (ab)usage of in_interrupt() and
related checks is happening.

hfa384x_cmd() and prism2_hw_reset() check in_interrupt() at function entry
and if true emit a printk at debug loglevel and return. This is clearly debug
code.

Both functions invoke functions which can sleep. These functions already
have appropriate debug checks which cover all invalid contexts, while
in_interrupt() fails to detect context which just has preemption or
interrupts disabled.

Remove both checks as they are incomplete, debug only and already covered
by the subsequently invoked functions properly. If called from invalid
context the resulting back trace is definitely more helpful to analyze the
problem than a printk at debug loglevel.

bd63bca5e0 net: iwlwifi: Remove in_interrupt() from tracing macro.
The usage of in_interrupt) in driver code is phased out.

The iwlwifi_dbg tracepoint records in_interrupt() seperately, but that's
superfluous because the trace header already records all kind of state and
context information like hardirq status, softirq status, preemption count
etc.

Aside of that the recording of in_interrupt() as boolean does not allow to
distinguish between the possible contexts (hard interrupt, soft interrupt,
bottom half disabled) while the trace header gives precise information.

Remove the duplicate information from the tracepoint and fixup the caller.

e4ff7d6b8c net: ipw2x00,iwlegacy,iwlwifi: Remove in_interrupt() from debug macros
The usage of in_interrupt() in non-core code is phased out.

The debugging macros in these drivers use in_interrupt() to print 'I' or
'U' depending on the return value of in_interrupt(). While 'U' is confusing
at best and 'I' is not really describing the actual context (hard interupt,
soft interrupt, bottom half disabled section) these debug macros originate
from the pre ftrace kernel era and their value today is questionable. They
probably should be removed completely.

The macros weere added initially for ipw2100 and then spreaded when the
driver was forked.

Remove the in_interrupt() usage at least..

c597ede403 net: brcmfmac: Convey allocation mode as argument
The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be seperated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

brcmf_fweh_process_event() uses in_interrupt() to select the allocation
mode GFP_KERNEL/GFP_ATOMIC. Aside of the above reasons this check is
incomplete as it cannot detect contexts which just have preemption or
interrupts disabled.

All callchains leading to brcmf_fweh_process_event() can clearly identify
the calling context. Convey a 'gfp' argument through the callchains and let
the callers hand in the appropriate GFP mode.

This has also the advantage that any change of execution context or
preemption/interrupt state in these callchains will be detected by the
memory allocator for all GFP_KERNEL allocations.

5c831644e1 rtw88: handle and recover when firmware crash
This handles the situation when firmware crashes.
When firmware crashes, it will send an interrupt, and driver will queue
a work for recovery.
In the work, driver will reset it's internal association state, which
includes removing associated sta's macid, resetting vifs' states
and removing keys. After resetting the driver's state, driver will call
rtw_enter_ips() to force the chipset power off to reset the chip.
Finally, driver calls ieee80211_restart_hw() to inform mac80211 stack
to restart.
Since only 8822c firmware supports this feature, the interrupt will only
be triggered when 8822c chipset is loaded.

1522ff731f mt76: mt7663s: introduce sdio tx aggregation
Introduce sdio tx aggregation to reduce bus transaction ands improve tx
throughput. For the moment the skb are copied in a dedicated buffer
since mmc APIs do not support sg table for zero-copy.
Since skb data are already copied in xmit_buff[], avoid linearization in
ma80211 layer. Relying on tx aggregation, we improve tx tpt of ~65%.

30bdd69246 mt76: add utility functions for deferring work to a kernel thread
In order to avoid keeping work like tx scheduling pinned to the CPU it was
scheduled from, it makes sense to switch from tasklets to kernel threads.

Unlike a workqueue, this one only allows one fixed worker function to be
executed by the worker thread. Because of that, there is less locking
and less code for scheduling involved.
This is important because the tx worker is scheduled often in a hot path

Because of that, there is no need to process the main data queue immediately

1daf2522fa mt76: mt7915: clean up station stats polling and rate control update
Queueing a per-sta work item from the tx free path can become very expensive
under load. This work is only supposed to pull rate control stats every
second and deal with rate control changes.

Additionally, the rate control update code was wrong, because it was
confusing bit masks and bit numbers in test_bit.

Fix this by introducing a dedicated device work item for rate control
updates, and by polling station stats from the phy mac work.
Stations requiring polling or rate control updates are added to lists
protected by dev->sta_poll_lock.

Note that rtw_wait_firmware_completion() was introduced with

efb1676306 mt76: mt7615: reduce maximum VHT MPDU length to 7991
After fixing mac80211 to allow larger A-MSDUs in some cases, there have been
reports of performance regressions and packet loss with some clients.
It appears that the issue occurs when the hardware is transmitting A-MSDUs

the value used for MT7915 as well.

In order to send VHT parameters to wcn3680 we need to pass the extended V1
parameter structures to the firmware. These commands need to have the

This patch makes the conversion. The conversion consists of

1. Setting the version number for wcn3680 or leaving it at 0 otherwise
2. Setting the size of the packet header lower for wcn3620 and wcn3660

Once done all three chips can continue to use the same code to pass
parameters to their respective firmware. In the case of the wcn3680 the
passed structures will be slightly larger to accommodate communication of

4e93810565 ath10k: Use bdf calibration variant for snoc targets
Board Data File (BDF) is loaded upon driver boot-up procedure.
The right board data file is identified using bus and qmi-board-id.

The problem, however, can occur when the (default) board data
file cannot fulfill with the vendor requirements and it is
necessary to use a different board data file.

Also using the chip_id for identifying the board data helps
in dealing with different variants of the board data file based
on the RF card. If the chip_id is not programmed, a default value
of 0xff will be used for parsing the board data file.

Add the support to get the variant field from DTSI and
use this information along with the chip_id to load the vendor
specific BDF.

The device tree requires addition strings to define the variant name

    wifi@a000000 {
            status = "okay";
            qcom,ath10k-calibration-variant = "xyz-v2";
    };

    wifi@a800000 {
            status = "okay";
            qcom,ath10k-calibration-variant = "xyz-v1";
    };

This would create the boarddata identifiers for the board-2.bin search

 *  bus=snoc,qmi-board-id=16,qmi-chip-id=0,variant=xyz-v1
 *  bus=snoc,qmi-board-id=17,qmi-chip-id=0,variant=xyz-v2

55bd149978 net: wilc1000: clean up resource in error path of init mon interface
The wilc_wfi_init_mon_int() forgets to clean up resource when
register_netdevice() failed. Add the missed call to fix it.
And the return value of netdev_priv can't be NULL, so remove
the unnecessary error handling.

cc20ff2c6b mac80211: swap NEED_TXPROCESSING and HW_80211_ENCAP tx flags
In order to unify the tx status path, the hw 802.11 encapsulation flag
needs to survive the trip to the tx status call.
Since we don't have any free bits in info->flags, we need to move one.
IEEE80211_TX_INTFL_NEED_TXPROCESSING is only used internally in mac80211,
and only before the call into the driver.

6aea26ce5a mac80211: rework tx encapsulation offload API
The current API (which lets the driver turn on/off per vif directly) has a
number of limitations:
- it does not deal with AP_VLAN
- conditions for enabling (no tkip, no monitor) are only checked at
  add_interface time
- no way to indicate 4-addr support

In order to address this, store offload flags in struct ieee80211_vif
(easy to extend for decap offload later). mac80211 initially sets the enable
flag, but gives the driver a chance to modify it before its settings are
applied. In addition to the .add_interface op, a .update_vif_offload op is
introduced, which can be used for runtime changes.

If a driver can't disable encap offload at runtime, or if it has some extra
limitations, it can simply override the flags within those ops.

Support for encap offload with 4-address mode interfaces can be enabled
by setting a flag from .add_interface or .update_vif_offload.
