For automatic testing packet injection can be useful.
Support injection through debugfs.

When a data packet is received, we need to make sure that we stay
awake until it can be processed and wait a while before trying to
enter runtime_suspend os system_suspend again. To do so, add a new
reference type for RX data and take the reference when sending the
packet to mac80211. We only do this for data packets, all the other
RX packets sent by the firmware (e.g. notifications) are not a reason
to prevent suspend.

If a host command was queued while in runtime suspend, it would go out
before the D0I3_END_CMD was sent. Sometimes it works, but sometimes
it fails, and it is obviously the wrong thing to do.
To fix this, have the opmode take a reference before sending a SYNC
command and make the pcie trans wait for the runtime state to become
active before actually queueing the command.

Improve current RSS configuration:
* Use netdev_rss_key instead of keeping a local copy.
* Configure also UDP hashing to have UDP traffic spread across queues.
* Do not direct RSS traffic to our fallback queue.

The initialization and copying of the RSS secret key
should not use ARRAY_SIZE as we need to initialize a
dword array, and not a byte array.
Fix also the hook maximum write size to allow writing
a longer table - up to full indirection table size.

When in AP mode we need to filter in beacons from other APs to update HT
operation mode. As a power optimization the beacons are filtered out when
there are no associated stations. As a result, when there are no
associated stations, we will not update the HT operation mode until a
station connects.
Add a debugfs parameter that allows to disable this optimization.

9000 series supports multi-queue rx. The hardware needs
to be configured with the hash functions to perform and
indirection table that maps hash results to the relevant
CPUs\queues.
Support this configuration.
Add debugfs hook to configure the indirection table in
order to enable performance analysis. The configuration
is stateless, receives a partial or full pattern and sends
the command to the firmware.

The driver should support also negative temperatures.
So there is a need to separate between the return value and
temperature in order to be able to distinguish between
a negative temperature and error value.

d0i3 commands are not supported in the init image, so take
a reference to ensure we don't enter d0i3 during init image,
and additional checks to prevent d0i3 commands when no
fw image is loaded.
Add a few WARN_ON_ONCE to the d0i3 enter/exit commands
to ensure we send d0i3 commands only when the normal
ucode is loaded.

Add ability to set the continuous recording mode of the FW, while
the FW debug data is configured to be stored on the NIC.
This could be useful for storing large segments of FW usniffer
debug data on the host, while having small store space on the NIC.
The host receives the usniffer data through the regular RX path, and
the data can get extracted using trace-cmd.

This was an old workaround for solving latency issues with
certain Miracast adapters like ActionTec. However this isn't
