I'm quite sure that CONFIG_ATH10K_DFS_CERTIFIED is enabled because the 3 debug file dfs_block_radar_events, dfs_simulate_radar, dfs_stats is
only created if CONFIG_ATH10K_DFS_CERTIFIED=y ? And I had these 3 files in my folder debug fs but "dfs_stats" show "DFS not enabled"

Yes I'm using backport v3.15 (latest) to build ath10k for my kernel 3.2.36 (provided by Marvell for my Marvell Armada 370 chipset).
I also download the folder ath from ath10k master branch (I got problem with seeing information of fw_stats from the version ath10k in backport).
Any suggestion? Please feel free to ask me more information if you need :D
