In a000 CDB firmware, we cannot update phy context to a
different band - we must first remove it and add it
again. Support this flow for all a000 devices since
we may have various combinations that cause us to fail
regardless if CDB is active.

The notification infrastructure (iwl_notification_wait_*
functions) allows to wait until a list of notifications
will come up from the firmware and to run a special handler
(notif_wait handler) when those are received.
The operation mode notifies the notification infrastructure
about any Rx being received by the mean of
iwl_notification_wait_notify() which will do two things:
1) call the notif_wait handler
2) wakeup the thread that was waiting for the notification
Typically, only after those two steps happened, the
operation mode will run its own handler for the notification
that was received from the firmware. This means that the
thread that was waiting for that notification can be
running before the operation mode's handler was called.
When the operation mode's handler is ASYNC, things get even
worse since the thread that was waiting for the
notification isn't even guaranteed that the ASYNC callback
was added to async_handlers_list before it starts to run.
This means that even calling
iwl_mvm_wait_for_async_handlers() can't guarantee that
absolutely everything related to that notification has run.
The following can happen:
Thread sending the command Operation mode's Rx path
-------------------------- ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
iwl_mvm_rx_common()
iwl_notification_wait_notify()
iwl_mvm_wait_for_async_handlers()
// Possibly free some data
// structure
list_add_tail(async_handlers_list);
schedule_work(async_handlers_wk);
// Access the freed structure
Split the 'run notif_wait's handler' and the 'wake up the
thread' parts to fix this. This allows the operation mode
to do the following:
Thread sending the command Operation mode's Rx path
-------------------------- ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
iwl_mvm_rx_common()
iwl_notification_wait()
// Will run the notif_wait's handler
list_add_tail(async_handlers_list);
schedule_work(async_handlers_wk);
iwl_notification_notify()
iwl_mvm_wait_for_async_handlers()
This way, the waiter is guaranteed that all the handlers
have been run (if SYNC), or at least enqueued (if ASYNC)
by the time it wakes up.

Currently when rate isn't found (invalid rate or CCK rate in high
band) driver is assigning rate -1, which causes mac80211 to dump
it later with the cryptic rate value of 0xFF.
Instead, warn early and dump the frame in mvm.

To utilize the maximum allowed tx power, an additional table was added
to the BIOS. The table consists of up to seven different regions
(currently only three are in use). Each region contains per band:
1. Maximum allowed tx power on the band.
2. Tx power offset for chain A.
3. Tx power offset for chain B.
On init flow driver reads this table by means of ACPI and
passes it to the firmware with GEO_TX_POWER_LIMIT cmd.
The firmware will use this table to enhance tx power with
the offset in the relevant table as well as verifying it does not
violate the maximum allowed tx power.

Change queue allocation to be dynamic. On transport init only
the command queue is being allocated. Other queues are allocated
on demand.
This is due to the huge amount of queues we will soon enable (512)
and as a preparation for TX Virtual Queue Manager feature (TVQM),
where firmware will assign the actual queue number on demand.
This includes also allocation of the byte count table per queue
and not as a contiguous chunk of memory.

In a000 transport we will allocate queues dynamically.
Right now queue are allocated as one big chunk of memory
and accessed as such.
The dynamic allocation of the queues will require accessing
the queues as pointers.
In order to keep simplicity of pre-a000 tx queues handling,
keep allocating and freeing the memory in the same style,
but move to access the queues in the various functions as
individual pointers.
Dynamic allocation for the a000 devices will be in a separate
patch.

Newer firmware versions will be able to handle all the
WMM-PS flows internally when we act as a GO. The firwmare
relies on the fact that the drivers puts frames for
different peers in different queues (DQA) to achieve this.
The driver will not be aware of the power state of the peers
anymore.
Tell the firmware about the WMM-PS parameters of earch peer
that connects to us so that it can know what are the
trigger-enabled ACs, the delivery-enableds ACs and the
Service Period length.
This API change is backward compatible since older firmware
versions will simply ignore the newly added values.
Since we don't support ieee80211 TSPECs for now, just copy
the trigger-enabled ACs to the delivery enabled ones.

a000 devices queue management is going to change significantly.
We will have 512 queues. Those queues will be assigned number
by the firmware and not by the driver.
In addition, due to SN offload having TX queue shared between TIDs
is impossible
Also, the ADD_STA command no longer updates queues status.
The only point of changing queue in the SCD queue config API.
From driver perspective we have here a new design:
Queue sharing and inactivity checks are disabled.
Once this is done, the only paths that call scd_queue_cfg command
are paths that alloc and release TX queues - which will make future
accommodation to queue number assignment by FW easier.
Since allocating 512 queues statically is not advisable, transport
will allocate the queue on demand, fill the command with DRAM data
and send it. This is reflected in the new transport API.

In a000 devices the TX handling is different in a few ways:
* Queues are allocated dynamically
* DQA is enabled by default
* Driver shouldn't access TFH registers - ucode configures it
all in SCD_QUEUE_CFG command
Support all this in a new API with op mode, where op mode sends
the command, transport will allocate the queue dynamically, fill
in DMA properties, send the command to FW and get the ID back.
Current implementation only sets the new transport API and fills
the DMA properties.
Future patches will complete the other parts.

Dynamic SAR allows changing TX power limits at runtime to comply with
SAR regulations on multiple form factors (e.g. tablet vs. clamshell
mode). To support this, a new table was added to ACPI, which is
called Extended Wireless Regulatory Descriptor (EWRD). This table
allows OEMs to define different TX power profiles for each form-factor
or usage mode.
Read this new table and store it in our SAR profiles table, in
preparation for Dynamic SAR support.

We are adding support for dynamic TX power tables for SAR (specific

(static) TX power table, which is read from ACPI, and use it
statically.
To prepare for more tables that can be switched dynamically, refactor
the SAR init flow to allow reusage and add the current static table as
a single entry in an array of tables.

Currently aux & broadcast queues are added before calling add
station, which results with a SCD_QUEUE_CFG command sent with
a station id unknown yet to fw.
While this works for pre-a000 firmware, the a000 fw requires
the order to be reversed.
The reason the change is only for a000 devices and not for
previous devices is that we cannot reverse the order since
the tfd_queue_mask containing the aux queue will cause FW to
assert on adding a queue mask with a queue that is not enabled.
This is not a problem in a000 fw since the tfd_queue_mask was
removed from the add sta API.

As per latest regulatory update for India, channel 52, 56, 60, 64
is no longer restricted to DFS. Enabling DFS/no infra flags in driver
results in applying all DFS related restrictions (like doing CAC etc
before this channel moves to 'available state') for these channels
even though the country code is programmed as 'India' in he hardware,
fix this by relaxing the frequency range while applying RADAR flags
only if the country code is programmed to India. If the frequency range
needs to modified based on different country code, ath_is_radar_freq
can be extended/modified dynamically.

Introduce a debugfs option to manually override the noise floor,
ignoring the automatically tuned noise floor of the driver/hw.
In my tests with a AR9580 based module and a tx99 5 MHz interferer,
I could tune the noisefloor to -95 dBm or above to allow communication
again. The automatic noise floor calibration sometimes could adapt to
the situation as well, but not reliably and permanently.
I would consider this "feature" experimental and interesting for people
debugging the noise floor calibration or other effects of the hardware.
