The variable info is assigned to point to bcdc->msg[1], which is the
same as pointing to bcdc->buf. As that is what we want to access
make it clear by fixing the assignment. This also avoid out-of-bounds
errors from static analyzers are bcdc->msg[1] is not in the structure
definition.

802.11d is not always supported by firmware anymore. Currently the
AP configuration of 11d will cause an abort if the ioctl set is
failing. This behavior is not correct and the error should be
ignored.

Booting multiple wl12xx and wl18xx devices using the same rootfs is
a pain. You currently have to symlink the right nvs file depending
on the wl12xx type.
For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin
by default and trying to bring up a wl128x based device:
wlcore: ERROR nvs size is not as expected: 1113 != 912
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR firmware boot failed despite 3 retries
Note that wl18xx uses a separate config firmware wl18xx-conf.bin
that can be generated with tools using the following two git repos:
git.ti.com/wilink8-wlan/18xx-ti-utils
git.ti.com/wilink8-wlan/wl18xx_fw
So let's not configure the nvs file for wl18xx as it's not needed
AFAIK. If it turns out that we also need the nvs file for wl18xx,
we can just add it to the config firmware data for wl18xx.
Let's fix the issue by using the chip specific config firmware
data, and make sure we produce understandable warnings if something
is missing.

In order to access cached/paged memory, there are a couple of firmware
commands (one for UMAC and one for LMAC) that let the host access memory
and registers indirectly. Since this is done by the firmware on behalf
of the host, even if memory is paged out or cached, the host will
retrieve the memory as the firmware sees it (paged out memory will get
paged in).
Export this mechanism via a debugfs entry for both read and write
access.
WARNING: This mechanism has no protections at all. Invalid addresses may
crash or hang the firmware. Writing to arbitrary memory also comes with
no guarantees.

There's no need for the common MAC context function to have an

There was recently a Full AP mode feature added where hostap adds
the station at auth stage, and not assoc.
However, when running with legacy hostapd, we get the auth response
before station was added, and tx_skb_non_sta fails to allocate
a queue, resulting in a complete failure of association.
Take care of this situation as well.
Add a warning when no valid queue is returned at all and make mvm
drop the packet instead of passing it on.
Refactor the function a bit while at it.

If adapter is null the error exit path in mwifiex_shutdown_sw is
to down the semaphore sem and print some debug via mwifiex_dbg.
However, passing a NULL adapter to mwifiex_dbg causes a null
pointer deference when accessing adapter->dev. This fix checks
for a null adapter at the start of the function and to exit
without the need to up the semaphore and we also skip the debug
to avoid the null pointer dereference.

Indeed, mwifiex_create_custom_regdomain() returns NULL in the
case that channel is missing in the TLV without freeing regd.
Moreover, some other error paths in this function return ERR_PTR
values which are assigned without checking to the regd field in
the mwifiex_adapter struct. The latter is only null-checked where
used.
Fix by freeing regd in the error path, and only update
priv->adapter->regd if the returned pointer is valid.

If the firmware ever decides to send any new/more notifications
to the RSS queues, the driver would currently try to interpret
those as REPLY_RX_MPDU_CMD and, if the notification was small,
access invalid memory.

Function is very indented. Go to msi section if needed to avoid
it and by that make the code more readable.

In order to utilize the host's CPUs in the most efficient way
we bind each rx interrupt vector to each CPU on the host.
Each rx interrupt is prioritized to execute only on the designated CPU
rather than any CPU.
Processor affinity takes advantage of the fact that some remnants of
a process that was run on a given processor may remain in that
processor's memory state for example, data in the CPU cache after
another process is run on that CPU. Scheduling that process to execute
on the same processor could result in an efficient use of process by
reducing performance-degrading situations such as cache misses
and parallel processing.

When a STA is removed in DQA mode, if no traffic went through
its reserved queue, the txq continues to be marked as
reserved and no STA can use it.
Make sure that in such a case the reserved queue is marked
as free when the STA is removed.
