In the file drivers/net/wireless/ath/dfs_pattern_detector.c we can found the ETSI pattern definition. In this definition we can found 7 patterns (0 to 6). The ETSI standard EN 301893 Annex D only specifies 6 patterns. Only the pattern 1 to 6 defined in the ath dfs pattern match with the ETSI standard. Why the pattern 0 is defined? Is it possible to remove this pattern and keep compliant with the ETSI standard? Thanks for your help. Cedric.
