Currently irrespective of dfs domain and radar detection activity pre-CAC results for a wiphy are retained till the wiphy is detroyed. This may not be preferred in non-ETSI dfs domain where pre-CAC is not explicitly mentioned in the respective DFS requirement spec. This patch set modifies the current behaviour of pre-CAC for non-ETSI domain by giving 2 seconds grace period for dfs master interface to start operating on the CAC completed channel.
This patch set also adds support to share dfs channel state across multiple radios of the same regulatory configuration.
