Consider the case where preCAC is running on channel 120 (20MHz)
bandwidth and 116 (20MHz) channel is already preCACed. One possible tree
structure, with the scenario mentioned above, is shown below:
122(1,0)
|
|------- 118(1,0)
| |
| |------- 116(1,0)
| |
| |------- 120(0,0)
|
|------- 126(0,0)
| |
| |------- 124(0,0)
| |
| |------- 128(0,0)
where 122 and 118 have 1 subchannel (116) as CAC done. While the preCAC
is running on 120(20Mhz), the preCAC is restarted with a new channel
of 40MHz bandwidth. If the new channel picked is 118(40Mhz) in which 116
is already CACed, once the preCAC is completed on 118 (40Mhz),
the entire band (with both 20MHz channels) will be marked as CAC done.
In the API "dfs_mark_tree_node_as_cac_done", the number of CACed
subchannel of the parent node is incremented without checking if the
child has been marked. In the above case, after preCAC is completed
on channel 118, each 20 MHz channels in channel 118 (116 and 120) are
marked individually in this API.
While marking the tree for preCAC completion on the subchannel 116,
the number of CACed subchannels is incremented to 2 for 122 and 118, but
124 is already marked. While marking the tree for preCAC completion on
the other subchannel (120), the CACed subchannels count is incremented
to 3 for 122 and since it cannot increment the subchannel count to more
than 2 for 118, it returns, leaving 128 unmarked. The preCAC tree
structure will now look like:
122(3,0)
|
|------- 118(2,0)
| |
| |------- 116(1,0)
| |
| |------- 120(0,0)
|
|------- 126(0,0)
| |
| |------- 124(0,0)
| |
| |------- 128(0,0)
which is wrong.
To fix the above problem, check if a tree node is already marked as
CAC done and only then increment their parent's CACed subchannels count.
This issue is not seen for other cases (e.g. marking NOL channels), since
preCAC can be performed on the same channel again (incase of different
bandwidths) whereas NOL marking is unique.

If radar is found on primary channel, aDFS channel change is triggered
immediately after marking the primary channels as NOL. This may result
in picking the channel that the AP may come up in, for agile DFS.
To avoid running aDFS on the pdev's current channel, restart
agile DFS engine after new channel is selected, in vdev response.
Also, consider the scenario where the device has two DFS pdev objects.
When the API "dfs_prepare_agile_chan" is called to start preCAC, it
uses a round-robin logic to pick a DFS object for preCAC and
the preCAC timer maybe started for a different dfs object than the
one calling it (argument of the function). But the channel width of
the preCAC channel is always fetched from the dfs object calling
the API, which may result in wrong channel width sent in adfs_start
command.
Use temp_dfs structure (indicating the DFS object picked for preCAC)
to fetch the channel width, instead of fetching it from the dfs
object passed as argument to the function.

While checking if the current channel overlaps with the
weather channel range, the first sub channel was checked if it is to
the left of weather channel start and the last sub channel was
checked if it is to the right of the weather channel end.
By the above logic, the API returns true only if the entire
weather channel range is within the current channel.
Fix the formula by checking if the first sub channel of the current
channel is to the left of the weather channel end and the last sub
channel is to the right of the weather channel start to find if any
of the current channel is a weather channel.

Sepate out the GET APIs for getting dfs_precac_enable and
dfs_agile_precac_enable so that getting these flags becomes independent
of each other.

While switching to 36 HT160 as part of multivdev restart, the channel
params to be sent to FW are only updated with primary segment dfs set flag.
Consider if the primary channel is 36 (non DFS), in which case, the
primary HT80 segment is non DFS, but secondary HT80 segment is DFS. This
will be indicated to FW by sending the flags with dfs_set as FALSE and
dfs_set_cfreq2 as TRUE. But since dfs_set_cfreq2 is not updated incase of
multivdev restart, FW does not detect radar in the secondary detector.
Add proper dfs_set_cfreq2 flag in multivdev_restart channel params.
