72a3356885 iwlwifi: mvm: ignore LMAC scan notifications when running UMAC scans
If the firmware sends LMAC scan notifications while a UMAC scan is
running, just WARN and ignore it, otherwise the scanning state gets
messed up.

e7c2e1fdcd iwlwifi: mvm: Enable MPLUT only on supported hw
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.

f9d716443f iwlwifi: mvm: Configure fragmented scan for scheduled scan
Configure the FW to use fragmented scan when the traffic load is high
or low latency traffic is on. This is useful for scans that are
managed by the FW (e.g. scheduled scan).

6c4fbcbc1c iwlwifi: add support for 12K Receive Buffers
802.11ac allows A-MSDU that can be up to 12KB long. Since
an entire A-MSDU needs to fit into one single Receive
Buffer (RB), add support for big RBs.
Since this adds lots of pressure to the memory manager and
significantly increase the true_size of the RX buffers,
don't enable this by default.

7d1620451d iwlwifi: nvm: fix up phy section when reading it
This is a workaround to an OTP bug. In Series 8000 1x1, the OTP
0xA052 defines 2x2 antenna configuration. This workaround overrides
the decision based on HW id and on MIMO disabled bit which is
correct in the OTP and set to disabled. This fixes the previous
workaround "force 1x1 antenna in Series 8000".
