Subject: [PATCH] dfs: enter DFS state if no available channel is found
|
|
|
|
Previously hostapd would not stop transmitting when a DFS event was
|
|
detected and no available channel to switch to was available.
|
|
|
|
Disable and re-enable the interface to enter DFS state. This way, TX
|
|
does not happen until the kernel notifies hostapd about the NOP
|
|
expiring.
