From 30ca8b0c4d6c9fb1d76e5894b1e8bf7c6a12224d Mon Sep 17 00:00:00 2001 From: Aditya Kumar Singh Date: Tue, 12 Sep 2023 10:48:55 +0530 Subject: wifi: cfg80211: export DFS CAC time and usable state helper functions cfg80211 has cfg80211_chandef_dfs_usable() function to know whether at least one channel in the chandef is in usable state or not. Also, cfg80211_chandef_dfs_cac_time() function is there which tells the CAC time required for the given chandef. Make these two functions visible to drivers by exporting their symbol to global list of kernel symbols. Lower level drivers can make use of these two functions to be aware if CAC is required on the given chandef and for how long. For example drivers which maintains the CAC state internally can make use of these.
