Subject: [PATCH] cfg80211: Fetch wiphy dfs domain if it is self managed
|
|
|
|
Currently during CAC start or other radar events, the DFS
|
|
domain is fetched from cfg based on global dfs setting.
|
|
|
|
But this could be different in case of self managed wiphy's
|
|
in case the self managed driver updates it database or supports
|
|
regions which has DFS domain set to UNSET in cfg80211 glocal
|
|
regdomain.
|
|
|
|
This avoids AP bringup failure for these self managed drivers
|
|
in certain countries.
