When using RSS on 9000 series devices, we can't rely on processing the
received frames for station powersave handling, since they could be
processed on different CPUs and out of order.
In order to still manage the powersave of stations, the firmware sends
a notification on sleep->wake, wake->sleep and - for U-APSD - frames
received with PM while already sleeping (with the TID.)
With this, the driver can set AP_LINK_PS, which is required for real
parallel RX. In addition, this requires checking for PS-Poll frames
and calling ieee80211_sta_pspoll() appropriately.

In commit 97f95c93c8 ("iwlwifi: remove support for fw older than
-16.ucode") we accidentally changed the fw version reading code for
DVM devices. The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore. But DVM devices still use the old FW API.
Fix that by bringing the code back in.

LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.
The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

Currently firmware is configured to filter out beacons. In case
a beacon was changed - it is waking the host.
However, some vendors change their IEs frequently without any
significant change, and redundant wakeups are triggered as a
result.
As a solution disable beacon filtering when entering d0i3.
Instead, firmware will store the latest beacon and upon exiting
d0i3 it will send it up to the host, so the host can act upon
changes (if there were any).
This beacon will arrive as a dedicated notification - support it
as well.

When there's a bt-wifi contention that requires arbitration,
we use a priority-based mechanism to decide which comm wins.
Over time, use cases become more and more complex, with multiple
concurrent active links with different traffic types and different QoS
requirements, on both WiFi and BT sides.
This, in turn, requires us to elaborate our prioritization mechanism.
However, our legacy products included hw that does not supports this,
so selectively enable this on specific hw - as signaled by the firmware.
