Hi folks, In the wireless regulatory database (for linux kernel), the radar signal detection (for DFS in 5 GHz wireless band) method for India region is not mentioned. As per best of my understanding, there are three detection ways, namely, DFS-FCC (US way) , DFS-ETSI (European way) and DFS-JP (Japanese way). So, my doubt is how the linux kernel or wireless firmware will decide which detection mechanism to use for India region ? Apologies if i am missing anything.
