e811ada7a6 iwlwifi: mvm: Upgrade to a new power management uAPSD API
Change power management implementation to support new host-device API
containing uAPSD parameters. Verify FW support for this new API.
Use the new power table command (0xA9) to configure power management.
Use the legacy command (0x77) if FW does not support the new API.
New file power_legacy.c is introduced for legacy implementation.

Since SCAN related handlers are much less likely than
beacon related handlers, reorder between them.

d64048edcd iwlwifi: mvm: Add support for connection monitor offload
The firmware supports periodic keep alive and beacon monitoring,
so advertise connection monitor offload capability by setting
IEEE80211_HW_CONNECTION_MONITOR flag. Implement missed beacons
notification handler. Call ieee80211_beacon_loss in case of
missed beacons, so AP probing by mac80211 can be triggered.

9ee718aa92 iwlwifi: mvm: add thermal throttling and CT kill
In order to avoid NIC destruction due to high temperature,
CT kill will power down the NIC.

To avoid this, thermal throttling will decrease throughput
to prevent the NIC from reaching the temperature at which
CT kill is performed.

4f59334bb4 iwlwifi: fix initialisation while RF-kill is asserted
If RF-kill is asserted while a device is initialized, the
firmware INIT image can now be run to retrieve the NVM
data and register to mac80211 properly. Previously, the
initialisation would fail in this scenario and the driver
wouldn't register with mac80211 at all, making the device
unusable.

51b6b9e029 iwlwifi: mvm: tell firmware to let multicast frames in
Without this command, the firmware will filter out all the
multicast frames. Let them all in as for now. Later we will
want to optimize this to save power.

afc66bb734 iwlwifi: mvm: optionally store D3 SRAM after resume
The D3 image SRAM is overwritten by the runtime image, so
it can't be accessed after resume. However, it can be very
useful to look at it to know what happened during D3, so
add the ability to store the image and make it available
in debugfs.

d110cb51cf iwlwifi: mvm: take the radio type / step / dash from TLVs
This data should taken from TLVs and not from the NVM. This
is true for the value written in CSR_HW_IF_CONFIG_REG too.

Also, no need to set the CSR_HW_IF_CONFIG_REG_BIT_MAC_SI bit
for 7000 devices which are the only devices currently
supported.
