Add PREVENT_PCI_LINK_RESUME(bit 14) in quirks to prevent
link resume, which can be used to simulate unrecoverable
PCIe link down.
It's a one-time configuration that will be cleared after
WLAN chip power off.
Usage:
echo quirks 0x4000 > /d/cnss/control_params

To avoid confusion, print xdump capabilities in following format:
<indicated>: <wl_over_bt> - <bt_over_wlan>
indicated: 1 means the capability has been set explicitly, 0 otherwise
wl_over_bt: 1 means collecting WLAN dump over BT is enabled, 0 otherwise
bt_over_wl: 1 means collecting BT dump over WLAN is enabled, 0 otherwise

Introduce the action 'xdump_bt_over_wl' for the existing
debugfs entry 'dev_boot' to facilitate the collection of
Bluetooth firmware dumps over WLAN.
Usage:
echo xdump_bt_over_wl > <debugfs_path>/cnss/dev_boot
To successfully execute this action, you must first enable
the feature 'Collect BT dump over WLAN' using the following
command and ensure that Wi-Fi remains enabled:
echo 2 > <sysfs_path>/cnss/user_config

During TPC power calculation, if AP advertises power constraint IE via
beacons, STA stores it and offsets it from the regulatory power limit
for that channel. But as per 802.11, this value needs to be offset from
country IE power instead. This logic causes further reduction of tx
power, hence remove the logic to offset value from power constraint IE
with the regulatory power limit.

In case host receive a bearer state switch request to non-WLAN
which is initiated by other modules, it moves the state to non-WLAN
without checking the status of the request.
If request was not accepted, then there is no need to change the
bearer state to non-WLAN.

When RX page pool buffers are forwarded by the network back to the
driver for TX, driver DMA maps the TX buffer but unmap during the
completion is skipped because the packet is still a page pool buffer.
This is leaking the IOVA address space, eventually no room will be
left for other DMA operations which results in DMA map failures.
Fix SMMU IOVA address leak in the TX completion path because of
page pool buffers.

Currently in a case where only RX page pool is enabled, when RX page
pool buffers are forwarded by the network stack to the driver for
TX due to IP forwarding, it is resulting in a NULL DMA address mapping.
Since the RX page pool NBUFs have struct sk_buff::pp_recycle flag set,
driver will end up calling dma_sync_single_for_device() for taking
care of the cache ops in the transmit direction. When TX page pool
feature is not enabled, NULL DMA address will be passed to the
dma_sync_single_for_device() API resulting in assert.
Check the status of TX page pool feature before invoking
dma_sync_single_for_device() to fix this issue.

Thread1 initiates fastrpc_req_mem_map and creates a map with a
reference count of 1. Meanwhile, Thread2 calls fastrpc_get_args,
and if take_ref is false, and it finds the same map with a
same reference count of 1. Subsequently, Thread1 encounters a failure
and triggering fastrpc_map_put, which decreases the reference count
and frees the map. However, Thread2 continues to use the map, leading
to issues because the map is already freed.

With the introduction of kernel version 6.13, the init_dummy_netdev
symbol has been made static and is no longer exported. Consequently,
drivers must now utilize alloc_netdev_dummy() to allocate and
initialize dummy network devices.
The current implementation defines the net_device structure as a
static instance within the driver. However, since alloc_netdev_dummy()
dynamically allocates and initializes the dummy netdev, assigning its
return value to a statically defined structure is incorrect and leads
to undefined behavior.
To address this, a pointer to a net_device structure should be added to
the host context. The driver should store the pointer returned by
alloc_netdev_dummy() in this new member. Additionally, appropriate
cleanup logic must be implemented to free the allocated dummy netdev
during driver teardown.
