struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.
The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

This appears to work around a deadlock regression that came in
with the LED merge in 6.9.
The deadlock happens on my system with 24 iwlwifi radios, so maybe
it something like all worker threads are busy and some work that needs
to complete cannot complete.

The firmware support for management frame protection has limitations:
- do not support cipher BIP-GMAC-128 and BIP-GMAC-256
- support cipher BIP-CMAC-128 and BIP-CMAC-256, except action frame with
action type 'not robust'.
Therefore, to simplify the logic, do not set the IGTK to firmware and
let the encryption of management frames be handled by upper layer.

During chip recovery (e.g. chip reset), there is a possible situation that
kernel worker reset_work is holding the lock and waiting for kernel thread
stat_worker to be parked, while stat_worker is waiting for the release of
the same lock.
It causes a deadlock resulting in the dumping of hung tasks messages and
possible rebooting of the device.

Currently, when using WCN7850 or QCN9274 as AP, ath12k always performs down
grade phy mode operation regardless of whether the firmware supports EHT
capability or not and then vdev will start in HE mode. When stations that
support EHT capability try to connect to the AP, the AP will set phy mode
to EHT after receiving the association request packet, and then send
WMI_PEER_ASSOC_CMDID command to firmware, AP’s firmware will crash.
This is because when the ath12k_mac_copy_sband_iftype_data() function
handles EHT capability, it does not copy the EHT capability into the
iftype[band][type] array according to the interface type. So, interface
type should not be used as an index to get eht_cap in
ath12k_mac_check_down_grade_phy_mode() function.
To address this issue, use types_mask to select the eht_cap in
ath12k_mac_check_down_grade_phy_mode() function.
This patch affects QCN9274 and WCN7850 because they have the same issue.

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core instead
of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.

Remove unnecessary includes from driver. The first step is to add
necessary includes to driver's header files to make them can be included
individually. Then, driver's C files include driver's header files first,
and check if still missed header files of kernel.
The results show that most C files only include driver's header files.
Only core.c needs to include additional linux/firmware.h.
Also sort includes in alphabetic order.

I noticed by random that rtl8xxxu includes linux/wireless.h even though it
doesn't need it. While investigating a bit more I found even more unused
include files:
#include <linux/init.h>
#include <linux/sched.h>
#include <linux/ethtool.h>
It looks like that the includes are just copied to every file without checking
if the file really needs the include. So more includes could be removed but
that would need more careful analysis per each file.
