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.

Before this change when peer rate stats are enabled,
TX/RX_PPDU_DESC nbuf was getting free in ol_ath_sched_ppdu_stats()
which is not proper as whoever is consumer should free the buffer.

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.
