According to the ETSI speculation, off-channel CAC has a
minimum timeout value of 6 mins (non-weather) and 1 hour (weather). The
maximum timeout value is 4 hours (non-weather) and 24 hours (weather).
Current implementation always took 60 seconds (1 min) as the default
preCAC timeout value. Add changes to implement proper timeout values
based on the channel (weather or non-weather). As part of this change,
add an API to determine if a channel is within this range based on
the edge channels of the given bandwidth.
The API (dfs_start_agile_precac_timer) is called inside
dfs_get_ieeechan_for_agilecac which is used to find the next channel
for agile CAC. Move dfs_start_agile_precac_timer outside
to functionally differentiate each APIs.

While picking a channel to start Agile CAC on, the current channel
width enum is checked if it is non zero and only then a channel is picked.
However, the channel width value of 0 indicates the width is 20MHz.
Check if the channel width value is not CH_WIDTH_INVALID and only then
start Agile CAC.

In the current Agile DFS design it is assumed that the agile detector's
bandwidth is always 80Mhz. However, the agile detector inherits the
bandwidth of the current operating channel with the following
mapping:
Current Chan BW --- > AGILE BW
20 20
40 40
80/80+80/160 80
Provide support for Agile DFS on 20/40/80MHz channels based on the
current channel's bandwidth. Maintain a Binary Search Forest,
with each Binary Search Tree (BSTree) rooted by an 80MHz channel
structure. These BSTrees are connected by the preCAC list.
The primary key (identifier) of each node in the BSTree is an IEEE
channel. Each level of the BSTree has a unique bandwidth.
Remove the three existing precac lists: precac_required_list,
precac_done_list, precac nol_list.
Maintain
1) regular CAC and preCAC
2) regular NOL and preCAC NOL
information in the same Binary Search Forest.
Operations available on the preCAC BSF:
1. Allocate nodes of each tree in the forest:
Use level order BST insertion to create and add individual nodes of
the tree.
2. Deallocate nodes of each tree in the forest:
Use an algorithm to add current node's right subtree to the last leaf
node and remove left nodes (from the root) iteratively [O(N)].
3. Print precac tree states:
Use morris preorder tree traversal to print the states of the nodes
in the entire forest.
User space command: radartool -i wifi[x] showprecaclists.
Example: For a HT80 channel list,
[Syntax of each node: <center_channel_ieee>(<CAC_status>,<NOL_status>)]
106(0,0)
|
|------- 102(0,0)
| |
| |------- 100(0,0)
| |
| |------- 104(0,0)
|
|------- 110(0,0)
| |
| |------- 108(0,0)
| |
| |------- 112(0,0)
4. Find a channel for preCAC for a given bandwidth:
Use the current status of the node to find the appropriate channel
from the Forest based on it's bandwidth. [O(N)]
5. Find if channel is preCAC done:
Search the tree (Binary tree search) which has the channel requested
and return the CAC status.
6. Mark/unmark the channel as CAC done:
Given a channel, find all 20MHz subchannels and mark/unmark as CAC
completed.
7. Mark/unmark the channel as NOL:
Given a channel, find all 20MHz subchannels and mark/unmark as NOL.

When the CAC timer is in progress and radar is detected, a NULL pointer
dereference is observed when the radar detected channels are removed
from etsi required lists and added to NOL.
This issue is seen as the next etsi precac entry in the etsi required
list is freed instead of the current etsi precac entry.
This issue is fixed by freeing the current etsi precac entry in the
etsi precac required list.

Currently if InterCAC support is enabled:
1. If the user configures a DFS channel in 80MHz mode, the
radio switches to an intermediate channel and the user
desired channel is added on the top of the lists of the
channels to be CACed using AgileDFS.
2. If the user configures a DFS channel in 160MHz mode, the
radio switches to an intermediate channel and the user
desired channel is split into two 80MHz channels and are
added on the top of the list.
3. After agile CAC is completed on the user configured channel,
the radio stays on the intermediate channel.
Change the current channel (and mode) back to user desired
channel, after agile CAC is completed on the desired channel.

When a channel is marked as radar detected and added to preCAC NOL
list, it is removed only from etsi precac done list, but not from etsi
precac required list. Since a channel that is part of NOL, cannot also be
a part of etsi precac required list, this needs to be corrected.
Therefore, once radar is detected on a channel, remove it from both etsi
precac required list and etsi precac done list.

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 is receiving 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 having to do a 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 radio has two
synthesizers, one of which can be used for A-DFS.
Host driver will configure an A-DFS channel along with maintaining
pre-CAC Done list of channels.
PreCAC list caching of channels is 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 apart of event
params has information if the preCAC is successful or not. If RADAR
is found on the agile channel, host receives indication through the
existing radar indication event. HOST identifies the detection as
agile channel radar using the detector id value.
For SBS mode, there can be 2 pdev's which can include DFS channels.
Although the preCAC list is maintained separate for each pdev,
preCAC can only be performed for a single pdev at a time.
This is implemented by making the host timer common
for both pdevs,i.e psoc level timer.
The following commands can be used to set/get preCAC enable,as long
regdomain is ETSI along with agile capability enabled in the target
advertised to host in WMI ready event.
