This patch series addresses the intersection of scan and DFS operations with multi-radio wiphy case. The changes allow for more flexible handling of scan and DFS operations when both operations are on different radios within a same wiphy. --- Changes in v2: - Half-open interval ([start, end[) frequency range check added for API: cfg80211_get_radio_idx_by_chan(). - In API ieee80211_is_radio_idx_in_scan_req(), WARN_ON() and abort logic added for unexpected case. - Function __ieee80211_is_scan_ongoing() renamed to ieee80211_is_scan_ongoing(). - The logic to handle ongoing roc work and scan with multi-radio wiphy is simplified in the function- ieee80211_is_scan_ongoing(). - Patch re-ordering is done. - Link to v1: https://lore.kernel.org/r/20250514-mlo-dfs-acs-v1-0-74e42a5583c6@xxxxxxxxxxx --- Aditya Kumar Singh (1): wifi: mac80211: Allow DFS/CSA on a radio if scan is ongoing on another radio Raj Kumar Bhagat (1): wifi: mac80211: Allow scan on a radio while operating on DFS on another radio Vasanthakumar Thiagarajan (1): wifi: cfg80211: Add utility API to get radio index from channel include/net/cfg80211.h | 11 ++++++++++ net/mac80211/cfg.c | 54 ++++++++++++++++++++++++++++++++++++++++++++-- net/mac80211/chan.c | 30 +++++++++++++++++++++++--- net/mac80211/ieee80211_i.h | 6 +++++- net/mac80211/offchannel.c | 5 ++++- net/mac80211/scan.c | 20 +++++++++++------ net/mac80211/util.c | 27 +++++++++++++++++++++++ net/wireless/util.c | 24 +++++++++++++++++++++ 8 files changed, 163 insertions(+), 14 deletions(-) --- base-commit: ea15e046263b19e91ffd827645ae5dfa44ebd044 change-id: 20250514-mlo-dfs-acs-33d7d9eea437
