It doesn't make sense to use the FW thermal monitoring only if we
have CONFIG_THERMAL, because then we use the default thresholds
etc. which may be different from what the firmware implements, as
we don't maintain them in the driver now. Only the CTDP code needs
to actually be under CONFIG_THERMAL.

plan to do so in the near future, so we can remove this option

For runtime PM to work with d0i3 code, a lot of integration work needs
to be done with the platform (e.g. the out-of-band wake up interrupt)
and we currently don't have any platforms where this integration
happened. So, this code has been pretty much stale for a while and
when someone enables it, it just breaks things.
Therefore, to simplify the code base and make sure no one enables this
by mistake, we will remove the whole code.
This is only the very start, much more work is needed.
Remove the places where we check iwl_mvm_is_d0i3_supported
but leave all the refs, those will be removed in a different

We need to use a different firmware for C0 versions of killer Qu NICs.
Add structures for them and handle them in the if block that detects
C0 revisions.
Additionally, instead of having an inclusive check for QnJ devices,
make the selection exclusive, so that switching to QnJ is the
exception, not the default. This prevents us from having to add all
the non-QnJ cards to an exclusion list. To do so, only go into the
QnJ block if the device has an RF ID type HR and HW revision QnJ.

The MAC context configuration always allowed multicast data frames
to pass to the driver for all MAC context types, and in the
case of station MAC context both when associated and when not
associated.
One of the outcomes of this configuration is having the FW forward
encrypted multicast frames to the driver with Rx status indicating
that the frame was not decrypted (as expected, since no keys were
configured yet) which in turn results with unnecessary error
messages.
Change this behavior to allow multicast data frames only when they
are actually expected, e.g., station MAC context is associated etc.

An earlier patch made sure that the queues are not lagging

Don't take the risk to change completely the entry
condition to iwl_mvm_release_frames, but don't update
the head_sn is the NSSN is more than 2048 packets ahead
of us. Since this just cannot be right. This means that
