Subject: [PATCH] ath9k: DFS - consider ext_channel pulses only in HT40
|
||
|
|
mode
|
||
|
|
|
||
|
|
The chip reports radar pulses on extension channel
|
||
|
|
even if operating in HT20 mode. This patch adds a
|
||
|
|
sanity check for HT40 mode before it feeds pulses
|
||
|
|
on extension channel to the pattern detector.
