93d5d10085 wlcore: consolidate tx_seq handling on recovery
Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.

This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.

A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.

When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.

This functionality is STA only currently.

37c68ea699 wlcore: fix link count in single-link-PSM optimization
commit 144614f3eebd7d only allowed a single active link when

Use 3 links as an indication for a single active link. Use the

f1e3e05156 mac80211: remove IEEE80211_HW_SCAN_WHILE_IDLE
There are only a few drivers that use HW scan, and
all of those don't need a non-idle transition before
starting the scan -- some don't even care about idle
at all. Remove the flag and code associated with it.

The only driver that really actually needed this is
wl1251 and it can just do it itself in the hw_scan
callback -- implement that.

afb43e6d88 wlcore: remove if_ops from platform_data
We can't pass pointers from the platform data to the modules, because
with DT it cannot be done.  Those pointers are not set by the board
files anyway.  It's the bus modules that set them, so they can be
safely removed from the platform data without changing any board
files.

Create a new structure that the bus modules pass to wlcore.  This
structure contains the if_ops pointers and a pointer to the actual
platform data.

18b559d5db mac80211: split TX aggregation stop action
When TX aggregation is stopped, there are a few
different cases:
 - connection with the peer was dropped
 - session stop was requested locally
 - session stop was requested by the peer
 - connection was dropped while a session is stopping

The behaviour in these cases should be different, if
the connection is dropped then the driver should drop
all frames, otherwise the frames may continue to be
transmitted, aggregated in the case of a locally
requested session stop or unaggregated in the case of
the peer requesting session stop.

Split these different cases so that the driver can
act accordingly; however, treat local and remote stop
the same way and ask the driver to not send frames as
aggregated packets any more.

In the case of connection drop, the stop callback the
driver is otherwise supposed to call is no longer
required.

1c33db782d wlcore: use separate HW queue for each AC in each vif
Start using the new hw_queue mechanism in mac80211 and give each AC in
each vif its own hw_queue number. This allows us to stop an AC in a vif
independently from other vifs.

Change the Tx watermark handling functions to count packets per AC in
vif. From now on fast links should not be able to hurt the throughput
of slow links on the same AC but on different vifs.

Change internal queue mgmt functions to operate per vif, to support the
new Tx watermark granularity. Make the global versions of the queue
stop/start functions to use the global mac80211 API for queue mgmt. This
helps in situations where the driver currently doesn't know all the vifs
that reside in mac80211. Recovery is a good example for such a case.

0e81047996 wlcore: improved Tx scheduling algorithm
Prioritize EDCA by choosing the AC before anything else. Use the
fast/slow link bitmap in FW to improve the scheduling algorithm for
the multi-link scenario.

Set packet thresholds to determine if a given link is high or low
priority according to its speed. A slow link will be given high priority
if the amount of packets queued for it in the FW is lower than the
slow-threshold. Similarly, a fast link will be given high priority if
the number of its packets queued in FW is smaller than the high-threshold.

The improved algorithm:
1. Choose optimal AC according to FW utilization
2. Traversing the VIFs in a round-robin fashion, try to choose a high
   priority link. Links are traversed in a round-robin fashion inside a
   VIF.
3. If no high priority links are found, choose the first non-empty
   (low priority) link found in the round robin.

6b70e7eb70 wlcore: add new reg-domain configuration command
In 18xx the calibration process of the PHY Cortex domain
requires to perform an active calibration of the channel
before it can be used for transmission. To fulfill world
wide regulatory restrictions, fw should be always
synchronized/updated with current CRDA configuration.
Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
fw with current reg-domain, this command passes a bit map
of channels that are allowed to be used for transmission.

The driver shall update the fw during initialization and
after each change in the current reg-domain
configuration. The driver will save the channel number of
incoming beacons during the scan process, as they might
be a result of the passive scan on
"IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
fw accordingly once the scan is finished, the purpose of
this is to be ready in case of the authentication request
on one of these disabled (uncalibrated) channels.

The new command requires to wait for the fw completion
event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".

No scan commands (including the sched scan) can be
executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
wl->mutex ensures that.

The scan APIs of 12xx and 18xx are totally different.
Use some common functions as much as possible (e.g.
for setting scan channels), but split scan.c into
chip-specific scan.c files, each implementing its
own scan mechanism.

(in other words - move most of the current wlcore's
scan.c into wl12xx, and implement a similar mechanism
in 18xx, according to the new api)

New wlcore ops are introduced in order to call the
chip-specific scan functions.

The template indices used for each scan (regular/scheduled)
are also different between the chips, so set the correct
indices used for each scan type after identifying the chip.

598b262a06 wlcore: don't call ieee80211_sched_scan_stopped directly
When we stop sched scan during connection, we shouldn't
call ieee80211_sched_scan_stopped directly, but do it
in the normal flow, as part of the SCHED_SCAN_COMPLETED
event handling.

ef08d0281a wlcore: avoid using goto in normal code flow
Remove goto and label in the code where a simple if can be used.  If
nothing else, this is at least confusing git diff, which shows the
label name as the name of the function.
