993ace39ef wifi: cfg80211: scan: skip duplicate RNR entries 
There really shouldn't be duplicate entries when we give
the list to the driver, and since we already have a list
it's easy to avoid.

While at it, remove the unnecessary allocation there.

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.

7391b2a4f7 wifi: iwlwifi: rework firmware error handling 
In order to later add the ability to do deeper resets of the
device when it crashes, first restructure the firmware error
handling. Instead of having just a single nic_error() method
that handles all, split it:
 - nic_error() just handles and prints the error itself,
 - dump_error() synchronously creates an error dump, and
 - sw_reset() will be called to request doing a SW reset.

This changes the architecture so that the transport is now
responsible for deciding how to do the reset, and therefore
the handling of reprobe if error occurs during reconfig
moves there, which necessitates adding a method there that
notifies the transport that the recovery was completed.

Actually introducing the model under which deeper resets can
be done will be in future patches.

99baaf924a wifi: iwlwifi: mvm: clean up FW restart a bit 
Approximately three years ago, in commit ddb6b76b6f
("iwlwifi: yoyo: support TLV-based firmware reset"), the code
was (likely erroneously) changed to no longer treat error
interrupts as firmware errors. As a result, this meant that
the fw_restart counter was only applied in case of command
queue being stuck, which never seems to happen. Also, there's
no longer any way to set the mvm->fw_restart to a value that
doesn't match exactly the module parameter behaviour.

Instead of trying to fix this, simply remove the logic that
limits the number of restarts, it's clearly unused.

However, restore the logic that restart isn't unconditional,
by checking the module parameter.

Since the "fw_error" argument to iwl_mvm_nic_restart() is now
always true (except in the "never happens" case of CMD queue
stuck), just remove it too and treat command queue stuck the
same way as everything else.
