Eran Harary 91479b64c9 iwlwifi: allow dynamic configuration of internal memory
New transport need to configure internal memory based on
the data in the (enlarged) alive notification from the
firmware. Add a transport API for this.

Emmanuel Grumbach a102292719 iwlwifi: remove CMD_SYNC
CMD_SYNC is really 0 which is confusing:

if (cmd.flags & CMD_SYNC) is always false.
Fix this by simply removing its definition.

Johannes Berg fde73834ea iwlwifi: nvm: remove reading valid antennas from NVM
These values aren't used as the firmware values should be used,
so reading them is pointless and hides potential errors when
somebody uses these values. Leave them zero to make it clearer
that they can't be used. We can't remove the struct members as
the DVM driver does read the values from EEPROM/OTP and the
structure is shared between drivers.

Ido Yariv 0c0e2c71b4 iwlwifi: mvm: handle platform PCIe power limitation
The tx backoff settings used by the thermal throttling mechanism can
also be used for enforcing a limit on the power consumption of the module.

Handle the platform PCIe power limitation by translating the limit
(measured in mw) to its respective tx backoff value. The translation is
module specific.

The resulting tx backoff value is sent to the ucode, and also serves as the
minimal backoff value that can be set by the thermal throttling mechanism.

Arik Nemtsov a408284367 iwlwifi: trans: divide stop_hw into stop_device/op_mode_leave
The stop_hw trans callback is not well defined. It is missing in many
cleanup flows and the division of labor between stop_device/stop_hw
is cumbersome. Remove stop_hw and use stop_device to perform both.
Implement this for all current transports.

PCIE needs some extra configuration the op-mode is leaving to configure
RF kill. Expose this explicitly as a new op_mode_leave trans callback.
Take the call to stop_device outside iwl_run_mvm_init_ucode, this
makes more sense and WARN when we want to run the INIT firmware while
it has run already.

Lilach Edelstein 1f3b0ff8ec iwlwifi: mvm: Add Smart FIFO support
Send firmware a Smart FIFO Configuration host command to allow
interrupt coalescing. The smart FIFO is enabled when there is
only one bound interface (other than  p2p devices which are
ignored) and it is of type station, and activated while the
station is associated.

Smart Fifo allows aggragations of DMA transactions and by that
causes processor and memory controller to stay for a longer time
on lower c-states, thus saving platform power.
Firmware relies on driver to activate and disable it.

It can configure the following: CAM (Continuous Active Mode) and
POWER_SAVE_ENABLE debug option. Send this command when firmware is

Note: Setting this command is important to avoid unwanted FW behavior.
It particularly fixes a bug when a device does not drop to low power
