ETSI standard defines "Offchannel CAC" as: "Off-Channel CAC is performed by a number of non-continuous checks spread over a period in time. This period, which is required to determine the presence of radar signals, is defined as the Off-Channel CAC Time.. Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time 4 hours..". mac80211 implementation refers to a dedicated hw chain used for continuous radar monitoring. Rename offchannel_* references to background_* in order to avoid confusion with ETSI standard.
