After NOL timeout, if ETSI PreCAC is supported, add the HT20 Channel

detach to avoid channels being added to ETSI PreCAC Required List when

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.

AP is configured to operate in Channel 100(HT80), and Zero Wait DFS
is enabled. Once PreCAC is complete on DFS Channels,inject radar in
Channel 100 and AP moves to another DFS channel 116 and beacons
immediately but station associated to AP still does a scan again.
When the station receives the Channel Switch Announcement from AP, it
dissociates from the AP and scans again.
Maximum Switch time Information Element can be used by the Station to
to know if the AP has done PreCAC on target channel. Maximum Switch Time
IE is part of AP's beacon and is the sum of CAC timeout on the target
channel and 1 beacon interval.
If PreCAC is done on target channel, the CAC timeout is zero and Maximum
Switch time IE is equal to 1 beacon interval. This element is sent to
Station along with Channel Switch Announcement. The Station receives the
maximum channel switch time element. If the value of maximum channel switch
time element is less then or equal to beacon interval, the station
associates with the AP seamlessly without dissociation. If the value of
the Maximum Channel Switch Time IE is greater than 1 beacon interval, then,
the Station has to dissociate from the AP since, ZeroCAC has not been done
by the AP.

Update NOL list based on the external radar information sent
from the action frame and store in DFS structure.
Add an utility - dispatcher function that can be called by UMAC
with NOL IE information.
In the DFS structure,
1). If subchannel marking is disabled, add all the current
channel's subchannels to NOL, do not update the NOL IE
structures inside dfs, and send a flag saying not to
propagate the NOL IE to uplink.
This is because, in case of cascading repeaters, one
of the repeaters (RE1) in the cascading system might have
subchannel marking disabled. In that case, sending the
same NOL IE to uplink results in RE1 and its BSS to disconnect.
2). If subchannel marking is enabled, add those subhannels to NOL,
and update flags saying NOL and RCSA IE should be sent.

Calculate the bitmap of subchannels that are affected by
radar and store in dfs structure along with flags
Algorithm:
1). Given the radar affected subchannels list, create a
NOL bitmap, where
1 - Radar hit on Subchannel.
0 - Subchannel not affected.
2). Along with the NOL bitmap, send the Minimum Bandwidth
for each subchannel and the Channel list's starting
channel's centre frequency.
Example:
Mode : 100HT80, if radar affected subchannels are 100, 104
and 108.
NOL bandwidth: 20.
NOL start frequency: 5500.
NOL Bitmap: 11100000.
3). During precac (precac timer running), if radar hits
at secondary segment, the umac code that sends rcsa
is still called, but add a new flag to not send rcsa, and
in rootAP, channel change is not triggered, only NOL
is updated.
Add APIs that can be called from mlme to fetch the NOL and IE
flags information from DFS structure during RCSA framing.
If subchannel marking is disabled, the new NOL bitmap has no meaning
and is hence, not sent.

issued. During preCAC, the second segment frequency stored in current
channel is invalid and it is stored in dfs itself.
Correct the condition for enhanced bangradar command. Update dfs_seg_id and

parameters when enhanced bangradar command is issued. This portion checks
for radar found segment id that would not have been updated yet. Use proper
