Currently ath12k only supports string type with bus, chip id and board id
such as "bus=ahb,qmi-chip-id=1,qmi-board-id=4" for AHB bus chip and
"bus=pci,qmi-chip-id=0,qmi-board-id=255" for PCI bus chip in board-2.bin.
For WCN7850, it is not enough to distinguish all different chips.
Add a new string type which includes bus, chip id, board id, vendor,
device, subsystem-vendor and subsystem-device for WCN7850.
ath12k will first load board-2.bin and searches in it for the board data
with the above parameters. If matched with one board data, ath12k downloads
it to firmware. And if not, downloads board.bin instead.

Currently ath10k defines the following struct:
struct wmi_start_scan_tlvs {
u8 tlvs[0];
} __packed;
Per the guidance in [1] this should be a flexible array. However, a
direct replace to u8 tlvs[] results in the compilation error:
flexible array member in a struct with no named members
This is because C99 6.7.2.1 (16) requires that a structure containing
a flexible array member must have more than one named member.
So rather than defining a separate struct wmi_start_scan_tlvs which
contains the flexible tlvs[] array, just define the tlvs[] array where
struct wmi_start_scan_tlvs is being used.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

caused bootup failure on QCN9274 hw2.0 platform. Incorrect hardcode DP
irq offset overwrite the CE irq, which caused the driver to miss the
mandatory bootup message from the firmware through the CE interrupt. This
occurs because the CE count differs between platforms. The revert has no
impact since the original change was based on an incorrect assumption.

The callers who trigger H2C will wait until a C2H event is received,

address from netdev before driver sets STA MAC to netdev again. Now MAC address

The build can become unreproducible if the list of files

In the `ath_set_channel()` function, we only reset surveys that are not
from the current channel. This leads to the accumulation of survey data for
the current channel indefinitely. This may not be the most optimal
approach, as we want the ACS to rely on the most recent survey.
So reset the survey data for the current channel at the start of each scan.

We observe some packets are discarded in ieee80211_rx_handlers_result
function for WCN7850. This is because the way to get multicast/broadcast
indicator with RX_MSDU_END_INFO5_DA_IS_MCBC & info5 is incorrect. It should
use RX_MSDU_END_INFO13_MCAST_BCAST & info13 to get multicast/broadcast
indicator.

When the MAC address read from the efuse data is invalid, warn the
user and use a random MAC address instead.
On a device I am currently using (Anbernic RG-ARC) with a rtw8821cs
the efuse appears to be incompletely/improperly programmed. The MAC
address reads as ff:ff:ff:ff:ff:ff. When networkmanager attempts to
initiate a connection (and I haven't hard-coded a MAC address or
set it to random) it fails to establish a connection.

Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()'
should check the return value before examining skb data. So convert
the latter to return an appropriate error code and propagate it to
return from 'wfx_start_ap()' as well. Compile tested only.

The specification says that this information should not be explicitly
included in the per-STA profile. However, we need this information
readily available in the BSS for userspace and also internally when
associating. As such, append the appropriate element before
adding/updating the BSS.
