What's the use case for this new parameter and the configuration having to explicitly enable this functionality? Is there a reason for not doing this in cases where the driver supports this capability? It looks like patches 1..8 were enabling this functionality automatically and it is only this final patch that makes it depend on a configuration parameter (which is default by default). > diff --git a/hostapd/hostapd.conf b/hostapd/hostapd.conf > @@ -143,6 +143,13 @@ ssid=test > +# Enable radar/CAC detection through a dedicated background chain available on > +# some hw.

Or maybe more importantly, when one should not enable this? Would use of that dedicated background chain result in some other capabilities getting reduced? This is also a bit unclear on what happens if the driver does not support this capability and radar_background=1 is explicitly set in the configuration. -- Jouni Malinen PGP id EFC895FA
