Set the correct sta_id in the SCD_QUEUE_CONFIG command sent
to the FW when enabling/disabling queues. This is needed in
DQA-mode to allow the FW to associate between queue and STA.
In case the queue isn't connected to a specific station but
rather is a static "generic" queue - the sta_id should be
set to 0x10 (max supported STA is 0x0f).

Support DQA queue sharing when no free queue exists for
allocation to a STA that already exists. This means that
a single queue will serve more than a single TID (although
the RA will be the same for all TIDs served).
We try to choose the lowest AC possible, to ensure the
shared queues have the lowest possible combined AC
requirements. The queue to share is chosen only from the
same RA's DATA queues as follows (in descending priority):
1. An AC_BE queue
2. Same AC queue
3. Highest AC queue that is lower than new AC
4. Any existing AC (there always is at least 1 DATA queue)
If any aggregations existed for any of the TIDs of the
shared queue - they are stopped (the FW is notified), but
no delBA is sent.

Support marking queues as inactive upon a timeout expiring,
and allow inactive queues to be re-assigned to other RA/TIDs
if no other queue is free.
This is done by keeping a timestamp of the latest frame TXed
for every RA/TID, and then going over the queues currently in
use when a new queue is needed, inactivating all those that
are inactive.

In non-shared queues, DQA requires re-configuring existing
queues to become aggregated rather than allocating a new
one. It also requires "un-aggregating" an existing queue
when aggregations are turned off.
Support this requirement for non-shared queues.

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.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.
The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

Newer firmware versions put different data in the memory
which is read by the driver upon firmware crash. Just
change the variable names in the code and the name of the
data in the log that we print withouth any functional
change.
On older firmware, there will be a mismatch between the
names that are printed and the content itself, but that's
harmless.

To be able to test low-latency behaviour properly, split the
different low-latency sources so that setting any one of them,
for example from debugfs, is sufficient; this avoids getting
the debug setting overwritten by other sources.
