ae969afe43 iwlwifi: mvm: rs: don't clear persistent fields
iwl_mvm_rs_rate_init() is called multiple times to re-init
the rate scaling statistics (e.g. after some idle time).

It clears all the lq_sta sta, including some fields that
shouldn't be cleared (e.g. debugfs pointers). Fix it
by adding a new 'persistent' sub-struct, and
avoid clearing it on (re-)init.

Move the initialization of the persistent fields to
rs_alloc_sta instead.

633e271326 mac80211: split sched scan IEs
Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.

This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).

As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the
split data.

HW scan request. Add a HW flag to indicate that the driver support
this. To hold the required data, create a separate structure for

different parts of the scan IEs.

use the correct new function type/argument.

e48393e8cf iwlwifi: mvm: Fix broadcast filtering
Current code did not allow sending the broadcast filtering command
for P2P Client interfaces. However, this was not enough, since once
broadcast filtering command was issued over the station interface
after the P2P Client connected, the command also attached the filters
to the P2P Client MAC which is not allowed (FW ASSERT 1063).

Fix this skipping P2P Client interfaces when constructing the broadcast
filtering command

34c8b24ff2 iwlwifi: mvm: BT Coex - avoid the shared antenna for management frames
If BT is active, we need to refrain from using the shared
antenna. This logic is done in the firmware when we use the
link quality tables. But for management frames, the rate is
written in the Tx command by the driver.
Hence the driver needs to make sure not use the shared
antenna when BT is active for any frames that don't use
the rate scale table such as management frames or multicast.
