In Partial-Offload, when a repeater is associated with Root-AP in
DFS channel. The Repeater STA will get connected with Root-AP and then
Repeater-AP comes up in the DFS channel but it does not send beacons.
The reason is, when a STA vap is UP and in connected state, CAC is
skipped. So, for Repeater-AP we send VDEV_UP before Spoof radar
pulses event. FW rejects the VDEV_UP sent by host and therefore
Repeater-AP will be in UP state but it does not send any beacons.
The fix is, while checking the condition if STA vap is set to true, we
also check whether spoof radar event is completed. If the spoof radar
event is not completed, then we will not skip CAC and then VDEV UP
will be sent after the Spoof radar event.

An extension of preCAC feature is Rolling CAC. The distinct difference
between these features is that the FW runs the off channel CAC
timer for a "finite" time for preCAC and runs the timer for "infinite"
time on an off channel. Hence the infrastructure built for
preCAC feature is being modified to accommodate RCAC feature as well.
Following are the modifications done:
1. Add an enum to represent various off-channel CAC modes.
2. Remove the 'static' declaration of few APIS so as to re-use them.
3. Add 'dfs_rcac_ch_params' to DFS PDEV object to store the RCAC

Feature Description:
FCC/JP domains do not support PreCAC. However, we can always start
beaconning in a channel if we have completed CAC in that channel for more
than or equal to the CAC period of that channel.
If an Agile engine is available and the next channel is known, we can
start CAC in the next channel using agile, while continuing the Tx/Rx
in the current channel. And when we want to start beaconning in the
next channel after a radar detection (or after/for a user request) we can
do so without any new CAC. This allows us to jump to the new channel
without having to disrupt any ongoing data traffic. This type of
continuous CAC in the next channel while operating in the current channel
is known as Rolling CAC.
Following changes are implemented:
I)Per DFS PDEV:
1) 'dfs_agile_rcac_freq' to store agile RCAC frequency.
2) 'dfs_agile_rcac_ucfg' to enable/disable RCAC feature.
II)Per DFS PSOC:
1) 'dfs_rcac_timer' is the only RCAC timer for the device/Psoc. This will
be shared by pdev level dfs objects.
2) 'dfs_rcac_timer_running' to indicate if RCAC is running or not.
III) New APIs:
1. A dispatcher API 'ucfg_dfs_set_rcac_enable' to set rcac config.
2. A dispatcher API 'ucfg_dfs_get_rcac_enable' to get rcac_config.
3. A dispatcher API 'ucfg_dfs_set_rcac_freq' to set user configured
rcac freq.
4. A dispatcher API 'ucfg_dfs_get_rcac_freq' to get the user configured
rcac freq.
5. Rolling CAC timer init/deinit APIs.

Current NOL conversion for dynamic mode switch is in such a way
that the NOL data is copied to the pdev ID entry for the targeted
mode. That is, the NOL data is split/merged before mode switch and
copied to a temporary structure before mode switch command is
sent to FW.
At this point, the target pdev's frequency range are still the old
values because of which, certain entries of the NOL data are missed.
Also in case of FW failures, the NOL entry cannot be added back
because they have been merged/split already.
To avoid the above, rearchitecture deinit and reinit NOL for
mode switch in such a way that the NOL data, as-it-is, is copied
before mode switch and is only split/merged after the frequency range
of the pdevs are properly mapped and the FW response is a success.

Supported dynamic HW mode switches:
DBS (full band 5G and 2G) <-> DBS_SBS (low band 5G, high band 5G and 2G)
Description of the changes:
1. NOL conversion:
a. Introduce a temporary NOL list copy structure in DFS psoc obj.
b. When mode switch is triggered:
i. Stop the NOL timers and clear the data, to avoid processing NOL
expiry during mode switch.
ii. Allocate the psoc NOL copy for the target num_radios.
iii. Store the NOL data of each radio to the target pdev ID
(pdev ID after mode switch) in the psoc NOL copy,
using a unified mux/demux API.
c. After mode switch is completed:
i. Resume NOL by re-initializing the list from the temporary psoc
copy.
ii. Free the psoc copy after mode switch is complete.
iii. Note: changes are made to support pause and resume of NOL,
increasing NOL timeout by a few milliseconds.
2. PreCAC list conversion:
a. When mode switch is triggered:
i. Stop the existing preCAC timer and send ADFS abort command to FW.
b. When mode switch is completed:
i. Unify/separate the preCAC list if the target mode is DBS/DBS_SBS
respectively, using a single API.
ii. Start ADFS again.
3. Radar detection lock:
a. While detecting radar, acquire a lock to avoid handling user triggered
mode_switch during this process. Release the lock once radar
processing is completed and CSA start is triggered.
4. Radar detection/CAC completion defer during mode switch:
a. While detecting radar or CAC completion, check if mode switch is
in progress. If yes, defer the processing and wait for mode switch to
complete before handling the events.
b. Note: Precedence is Radar over CAC, i.e., if CAC processing is waiting
and radar is received, CAC completion is no longer handled.

Enable configurable dfs_pri_multiplier. The ETSI typ2 type3 radar
detection ratio is lower than expected(>80%) while channel loading is
high(>30%). The host improvement for this are:
1. Add configurable dfs_pri_multiplier, controlled by
DFS_PRI_MULTIPLIER. Default value 2, min 1, max 10.
2. Lower adrastea ETSI type 2/3/4 radar filter rssi_threshold,
controlled by DFS_OVERRIDE_RF_THRESHOLD, dfs log shows that
QCS405 target report RSSI range [18, 45] while radar power
is 3 dbm. By using default rssi_threshold 24 will reject
many radar pulses, which leads to low detection ratio.
3. Calculate deltapri for each searchpri based on dfs_pri_multiplier
in dfs_count_the_other_delay_elements(), check deltapri
between [1, dfs_pri_multiplier] * refpri and searchpri, if
the primargin is desired, mark it as matched pulse.
4. Pick lowpri as refpri for the radar filter with
rf_ignore_pri_window equals to 0 while DFS_PRI_MULTIPLIER is
enabled. Observed original findref logic has some problems
which selects refpri is bigger than lowpri, which leads to
the lowpri pulses pri_match are set to 0, and in this case,
radar was not detected. Example for the issue, assume
rf->rf_pulseid 34 (ETSI type 2) has 7 pulses with pri:
1489, 2978, 2978, 2978, 1489, 2978, 1489 us in this case,
highscore is 4 (2978), scoreindex is 5, refpri is 2978, which
leads to: index 0, 4, 6 pulses with pri_match 0 in
dfs_count_the_other_delay_elements(). The fix is to select
lowpri as refpri(1489 in this case).

Agile DFS support depends on the Firmware's aDFS support. This
information is propagated to the HOST in the WMI ready event as a flag.
This flag was not used by HOST before enabling agile DFS which resulted
in preCAC being enabled for the FW that does not support them.
Also, for certain chainmask configurations, aDFS should be enabled
only if the current pdev is operating in non 160 BW.
Introduce two new flags in the DFS object:
1. dfs_fw_adfs_support_160

In dfs_check_for_cac_start API, the following checks (in addition
to few more unchanged ones) are done:
1. If CAC timer is running, is the current channel a subset of the
CAC started channel (dfs_cac_started_chan).
2. If CAC timer is not running, is the current channel a subset of the
last CAC started channel and was the last CAC not aborted.
The variable dfs_cac_started_chan is filled when CAC timer is started. It
is then reset only if, after vdev response, if the new channel is non DFS
or when the next CAC timer is started (with new channel value).
With the above logic, the cases where CAC is not skipped for a DFS
channel (e.g. preCACed channel) is not taken care of.
Consider the following scenario:
1. The current channel is 100 and the preCAC is completed on all
channels.
2. When CAC is started on this channel (100), the dfs_cac_started_chan
becomes 100.
3. If radar is found on 100 and the new channel selected is one
of the preCACed DFS channels, CAC is skipped.
dfs_cac_started_chan still remains 100.
4. After NOL timeout, if the radio is switched back to 100, the last
CAC started channel is 100 and new channel is also 100, which results
in CAC being skipped.
Rewrite the dfs_check_for_cac_start logic by checking the following:
1. If CAC timer is running, check if the current channel is a
subset of dfs_cac_started_chan.
2. If CAC timer is not running, check if the current channel is a
subset of previous channel (input).
Clear the dfs_cac_started_chan when the CAC timer stops or expires.
Also, in the API "dfs_is_subset_channel", while checking if one channel
is a subset of another, the DFS subchannels are determined based on the
channel flags. This is handled for two cases:
1. If secondary channel alone is DFS.
2. If primary and secondary channels are DFS.
The case "If primary channel alone is DFS" is not handled.
In case of channel 116HT80_80 with secondary 80 being non DFS,
all subchannels are considered as DFS subchannels.
Add a new API "dfs_find_dfs_sub_channels" where all the above
mentioned cases of DFS channels are handled to find proper DFS
subchannels.

Agile Dynamic Frequency Selection refers to the mechanism in which DFS
scanning takes place on a separate dedicated synthesizer
(agile DFS sythesizer), while the access point receives data on a
separate channel. Once DFS scanning completes in the aDFS
synthesizer, AP can switch its primary channel to this preCAC done
channel, without Channel Availability Check of 60 seconds.
Hawkeye has native support for A-DFS unlike Cascade, which uses a
dedicated radar detector for background scanning. Each Iron radio has
two synthesizers, one of which can perform A-DFS.
Host driver configures an A-DFS channel along with maintaining
pre-CAC Done list of channels. PreCAC list caching of channels
is currently limited to ETSI domain.
Once off channel CAC completes in the agile channel, HOST receives O-CAC
complete indication. O-CAC status included as a part of event params
has information if the preCAC is successful or not. HOST also receives
indication through radar indication event handler, upon RADAR detect.
The detection is read as agile channel RADAR using the detector id value.
For SBS mode, there can be 2 pdev's which can comprise of DFS channels.
Although the preCAC list is separate for each pdev, preCAC timer is
limited to a single pdev.
The following commands are to set/get preCAC enable. Prerequisite to
enable preCAC includes regdomain to be in ETSI along with agile capability
enabled in the target.

If user configures DFS channel in 160MHz mode,
1. change mode to 80MHz and do PreCAC on primary and
secondary channels of 160MHz.
2. Use intermediate channel to operate.
3. Once PreCAC done on the both primary and secondary channels and is clear
then change mode back to 160MHz.
4. Change the channel from intermediate to configured DFS channel.
Use Broadcast and Unicast OMN frame to notify mode change.

Add API to update cmn vdev mlme structures,
with the addition of new members to the new mlme
vdev structure,new api's are required to update
those members which will be subsequently used the
new mlme target if layer to send commands to the firmware

The unit test command being sent to FW for bangradar did not have
enough arguments to perform subchannel marking as expected.
Pack in the existing uint32_t argument the following information
1). Segment ID (2 bits)
2). Chirp Information (1 bit)
3). Frequency Offset (8 bits [can be signed]).
that is being sent in the unit test command structure.

Replace all three radar simulation commands with a single variant which
will perform required functionality based on its number of arguments.
Existing variants of radar simulation commands:
1). Bangradar:
Description: Adds all subchannels of segment ID "0" in the
current channel to NOL.
Syntax: radartool -i wifi0 bangradar.
2). Second Segment Bangradar:
Description: Adds all subchannels of segment ID "1" of the
current channel to NOL.
Syntax: radartool -i wifi0 secondSegmentBangradar.
3). Enhanced Bangradar:
Description: Adds the radar infected subchannels computed based
on segment ID (X), chirp information (Y) and
frequency offset (Z) to NOL.
Syntax: radartool -i wifi0 bangradarenh X Y Z.
where,
X - Segment ID.
Y - Is chirp/non chirp.
Z - Frequency offset.
New radar simulation command:
Bangradar:
Types of usage:
1). No arguments:
Description: Adds all subchannels in the current channel to NOL.
Syntax: radartool -i wifi0 bangradar.
2). 1 Argument:
Description: Adds all subchannels of segment ID "X" of the
current channel to NOL.
Syntax: radartool -i wifi0 bangradar X
3). 3 Arguments:
Description: Adds the radar infected subchannels computed based
on segment ID (X), chirp information (Y) and
frequency offset (Z) to NOL.
Syntax: radartool -i wifi0 bangradar X Y Z
where,
X - Segment ID.
Y - Is chirp/non chirp.
Z - Frequency offset.
All other combinations of arguments will result in error (insufficient
arguments).
