The swap box flag of firmware is not set before htc ready, then it
will not set swap box flag in ath10k driver, and it will let swap
box setting not same between firmware and ath10k driver, then it
will trigger firmware assert failure.
Check the flag and set swap box after htc ready will fix the firmware
assert failure.

The hw-restart crash inject mode is a special mode, where
there is no crash generated in the firmware, but instead
the driver restarts the firmware. In order to restart WCN3990
firmware, the driver needs to send qmi_wlan_disable message
followed by the qmi_wlan_enable message to the WCN3990 firmware.
Currently the qmi_wlan_disable message is not sent to
the WCN3990 firmware when hw-restart crash is injected,
which causes the firmware to crash when the driver sends
qmi_wlan_enable message during ath10k_restart.
Send qmi_wlan_disable to the WCN3990 firmware when the
hw-restart crash is injected via debugfs.

On Denverton's integration of the Intel(R) Trace Hub (for a reference and
overview see Documentation/trace/intel_th.rst) the reported size of one of
its resources (RTIT_BAR) doesn't match its actual size, which leads to
overlaps with other devices' resources.
In practice, it overlaps with XHCI MMIO space, which results in the xhci
driver bailing out after seeing its registers as 0xffffffff, and perceived
disappearance of all USB devices:
intel_th_pci 0000:00:1f.7: enabling device (0004 -> 0006)
xhci_hcd 0000:00:15.0: xHCI host controller not responding, assume dead
xhci_hcd 0000:00:15.0: xHC not responding in xhci_irq, assume controller is dead
xhci_hcd 0000:00:15.0: HC died; cleaning up
usb 1-1: USB disconnect, device number 2
For this reason, we need to resize the RTIT_BAR on Denverton to its actual
size, which in this case is 4MB. The corresponding erratum is DNV36 at the
link below:
DNV36. Processor Host Root Complex May Incorrectly Route Memory
Accesses to Intel® Trace Hub
Problem: The Intel® Trace Hub RTIT_BAR (B0:D31:F7 offset 20h) is
reported as a 2KB memory range. Due to this erratum, the
processor Host Root Complex will forward addresses from
RTIT_BAR to RTIT_BAR + 4MB -1 to Intel® Trace Hub.
Implication: Devices assigned within the RTIT_BAR to RTIT_BAR + 4MB -1
space may not function correctly.
Workaround: A BIOS code change has been identified and may be
implemented as a workaround for this erratum.
Status: No Fix.
Note that 5118ccd347 ("intel_th: pci: Add Denverton SOC support") updates
the Trace Hub driver so it claims the Denverton device, but the resource
overlap exists regardless of whether that driver is loaded or that commit
is included.

WCN3990 sends tx completion of multiple management
frames bundled together in a single event, if the
host driver exposes the support to handle this
bundled tx completion event. This reduces the number
of WMI events which are sent to the host driver by
the target.
Set the BUNDLE_TX_COMPL flag in the host capability
flags when host sends the wmi init command, to indicate
the host capability to handle bundled tx completion for
management frames.
