CAC question: DFS -> non-dfs -> DFS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

While poking at the MTK driver and trying to fix some CAC bugs in it,
I noticed the following:

Select ch 100, which enables DFS CAC logic.  Wait for that to finish.
Then select CH 36 (disable DFS)
Then select ch 100 again, and the chandef->chan->dfs_state is set back to 0
which I think means we must do CAC again.

I was expecting in this case that the DFS state would be set to NL80211_DFS_AVAILABLE
instead, since CAC just passed a few minutes prior?

Thanks,
Ben
