====================
wireless-drivers-next patches for v5.10
Third set of patches for v5.10. Lots of iwlwifi patches this time, but
also few patches ath11k and of course smaller changes to other
drivers.
Major changes:
rtw88
* properly recover from firmware crashes on 8822c
* dump firmware crash log
iwlwifi
* protected Target Wake Time (TWT) implementation
* support disabling 5.8GHz channels via ACPI
* support VHT extended NSS capability
* enable Target Wake Time (TWT) by default
ath11k
* improvements to QCA6390 PCI support to make it more usable

ath.git patches for v5.10. Major changes:
ath11k
* improvements to QCA6390 PCI support, adding essential missing
features: ELF board files, packet log handling to avoid data stalls
and crash fixes

In bmps mode, beacons are filtered, and firmware is in charge
of monitoring the beacons and report changes or loss.
mac80211 must be advertised about such change to prevent it's
internal timer based beacon monitor to report beacon loss.
Fix that by setting/clearing the IEEE80211_VIF_BEACON_FILTER
vif flag on bmps entry/exit.

Host sends wmi command to allow hardware enter idle power
save mode in ath11k_mac_op_start function.
hw parameter idle_ps indicates whether idle power save is supported.

For QCA6390, Start a timer to update CE pipe 4 ring HP when shadow
register is enabled. Its' to avoid that HP isn't updated to target
register.

The timer is to check if TCL HP isn't updated to target.
The timer will postpone itself if there are TX operations
during the interval, otherwise the timer handler updates
the HP again so the index value in HP register will be
forwarded to target register, and the timer stops afterwards.

To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.
Update the shadow config whenever power up happens.
This feature is controlled by hw parameter supports_shadow_regs which is only
enabled for QCA6390.

For QCA6390, host can read and write registers below unwindowed
address directly without programming the window register. For
registers below bar0 + 4k - 32, host can read and write regardless
of the power save state. Shadow registers are located below
bar0 + 4K - 32.
Before MHI power up, there is no need to wakeup MHI so ini_done is
added to indicate it.

With QCA6390 when doing rmmod the kernel crashed. The reason was that the
destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy()
accidentally had swapped the debugfs directories and
ath11k_debugfs_soc_destroy() was removing an already removed directory, which
crashed the kernel.
The source of confusion is badly named function and variable names. I think the
best way to clean this up is actually to merge the corresponding functions, but
that's for another patch. Let's first just fix the crash.

For QCA6390 we first need to call free_irq() and only then disable_msi(). Otherwise a
kernel BUG below will happen. Also free core, hal_srng and ce resources during

Add packet log support for QCA6390, otherwise the data connection will stall
within a minute or so. Enable it via debugfs and use trace-cmd to capture the
pktlogs.
echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter
The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.
As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.
For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

QCA6390 does not support monitor mode at the moment so disable it altogether,
using a hack as mac80211 does not support disabling it otherwise. Add a boolean
to hw_params to know if hardware supports monitor mode.
IPQ8074 continues to support monitor mode normally.

There are different versions of QCA6390. Check TCSR_SOC_HW_VERSION to make sure
that the device is hw2.0, all the rest are unsupported.
This needs to be checked after ath11k_pci_claim() so move the whole switch choosing hw_ver.

As QCA6390 does not support mesh interfaces, move the interface_modes to
hw_params. Also create interface combinations dynamically so that it's easy to
change the values.
Now QCA6390 does not claim to support mesh interfaces to user space, but
IPQ8074 continues to do that.

For QCA6390, station vdev needs to delay startup but not for AP mode. On AP
mode vdev starts up immediately after bss peer is created in chanctx assignment
context.
This patch does not affect IPQ8074 family of devices.

The QCA6390 board I have, model 8291M-PR comes with an ELF board file. To get
this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then
added this patch to check for ELF magic string in the beginning of the file.
If that is found, use type ELF. After this the driver loads.

Add support for the new version of the alive notification, which

The scan request may specify the request scan dwell time.
However, this value may not always be optimal (e.g. short dwell
time for a passive channel). This may happen in a scan request
as a result of beacon report request, in which the AP may request
an active scan, thus setting a short dwell time, but the station
will perform a passive scan due to regulatory.
Ignore the scan duration parameter and always use the internal
scan dwell time which should be optimal.

firmware to do GTK rekeying for more algorithms (GCMP 128, GCMP 256,
SAE).
