9eca1abfb4 wifi: iwlwifi: mvm: improve/fix chanctx min_def use logic 
There are two cases in which the min_def isn't used:
 a) if FILS will be enabled
 b) if FTM responder is enabled

Both of these apply to AP mode only, but for FILS we're
not checking that right now. Change the code to iterate
the interfaces and links using the channel context, and
check for AP mode for both, not just for FTM responder.

In the case of iwl_mvm_enable_fils() this might also fix
an issue where FILS is enabled for an IBSS network that
happens to be started on 6 GHz, though that's not very
likely to be possible due to regulatory.

However for RX OMI bandwidth reduction the driver needs
to use the min_def in client mode as well, in order to
actually reduce bandwidth when it requested that.

9673c35486 wifi: iwlwifi: implement product reset for TOP errors 
The TOP is a shared (between BT and WiFi) hardware component,
and if it has an error we need to reset the whole device, i.e.
both BT and WiFi. This is achieved by calling a specific ACPI
DSM (device-specific method) with the right arguments before
doing a reset via the object referenced by _PRR.

Since this is needed here, but a function reset will always do
better than just re-enumerating the bus in case of errors, we
can always try to at least do a function reset and do the full
product reset only when needed for TOP errors.

Also, for some Bz and Sc devices where BT is PCIe/IOSF as well,
find the BT device and unbind that device as well so the BT
driver can recover from the reset that's going to happen,
rather than having to somehow detect that the device was reset.

Also add - currently unused - the function reset mode, this is
going to get used in the upcoming escalation model.

da7f40c05c wifi: mac80211: add some support for RX OMI power saving 
In order to save power, it can be desirable to change the
RX operating mode using OMI to reduce the bandwidth. As the
handshake must be done in the HTC+ field, it cannot be done
by mac80211 directly, so expose functions to the driver to
request and finalize the necessary updates.

Note that RX OMI really only changes what the peer (AP) will
transmit to us, but in order to use it to actually save some
power (by reducing the listen bandwidth) we also update rate
scaling and then the channel context's mindef accordingly.

The updates are split into two in order to sequence them
correctly, when reducing bandwidth first reduce the rate
scaling and thus TX, then send OMI, then reduce the listen
bandwidth (chandef); when increasing bandwidth this is the
other way around. This also requires tracking in different
variables which part is applicable already.

79f4b6934d wifi: iwlwifi: mvm: remove unneeded NULL pointer checks 
Smatch reported that we dereference the data pointer to calculate the
expected length before we check it's not NULL. While this is true (and
hence needs to be fixed), this will never happen because the data
pointer comes from struct iwl_rx_packet object which has the following
layout:

struct iwl_rx_packet {
        __le32 len_n_flags;
        struct iwl_cmd_header hdr;
        u8 data[];
} __packed;

So, if the pointer to iwl_rx_packet is valid, data will be valid as
well.

Remove the NULL pointer check on 'data' to avoid confusing smatch.
Also remove the check from similar functions in the same flow that were
cargo cult copy-pasted.

My recent restart related work has made this race more likely
to happen and we've now noticed it, but it seems that it was
always possible. The race is that the add stream work can be
scheduled just before a restart is scheduled and then execute
before the restart, accessing the device while it's doing the
restart and not accessible.

To fix this, check if the device is restarting and abort the
work in that case. Reschedule it after the restart as well.
