mac80211 constantly monitors the connection to the associated AP
in order to check if it is out of reach/dead.
This is absolutely fine most of the time.
Except when there is a scheduled scan for the whole neighborhood.
After all this path could trigger while scanning on different channel.
Or even worse: this AP probing triggers a WARN_ON in rate_lowest_index
when the scan code did a band transition!

* Deprecate the "debug50" module parameter used to obtain
5000 series and up debugging. Replace it with "debug" module
parameter to match with original driver and be consistent
between them. The "debug50" module parameter can still be used,
except that the module parameter is not writable in keeping
with its previous state. We currently just mark it as "deprecated"
and do not have it in the feature-removal-schedule. Some more
cleanup of module parameters needs to be done and can then be
entered together.
* Only make "debug" module parameters visible if the driver
is compiled with CONFIG_IWLWIFI_DEBUG. This will eliminate
a lot of confusion where users think they have set debug flags
but yet cannot see any debug output.
* Make module parameters writable. This eliminates the need for the
"debug_level" sysfs file, which can now also be deprecated and
added to feature-removal-schedule. This file is in significant
use though with many iwlwifi documents and text referring users
to it. We can thus not take its removal lightly and keep it around.
With iwlcore shared between iwlagn and iwl3945 we really do not need
debug module parameters for each but can instead have one debug
module parameter for the iwlcore module. The same issue is here as
with the sysfs file - a lot of iwlwifi documentation and text (like
bug reports) rely on iwlagn and iwl3945 having this module parameter,
so changing this to a module parameter of iwlcore will have significant
impact and we do not do this for that reason.
One consequence of this patch is that if a user is running a system
with both 3945 and later hardware then the setting of the one module
parameter will affect the value of the other. The likelihood of this
seems low - and even if this setup is present it does not seem like an
issue for both modules to run with the same debug level.

when the user wasn't really sure what they were doing,
like setting the BSSID back to the same value it was.
However, this optimisation should only be done while
associated so that setting the BSSID back to the same
value that it was actually triggers a new association
if not currently associated. To achieve, that, put the
