However, with Multi-Link Operation (MLO), there is a need to handle link specific data structures based on the actual operational link_id during channel switch operation. Hence, add support for the same. Non-MLO based operations will use link_id as 0 or deflink member as applicable. While at it, beacon count down now needs to be updated on proper link_id's beacon, do that as well. Aditya Kumar Singh (5): wifi: cfg80211: send link id in channel_switch ops wifi: mac80211: update beacon counters per link basis wifi: mac80211: handle set csa/after_csa beacon on per link basis wifi: mac80211: start and finalize channel switch on link basis wifi: mac80211: add support to call csa_finish on a link --- v7: * fixed proper link id validation in 2/5 and 5/5. (>=) * added comma in trace print in 1/5 v6: * splitted v5 2/3 into v6 3/5, 4/5 and 5/5 * rephrased commit mesage in 1/5 v5: * fixed compilation issue reported by kernel test robot. v4: * fixed compilation issue reported by kernel test robot. * rebased on latest ToT. * moved link_id arguement into csa_params struct in [1/3] v3: * splitted [v2 1/2] into [v3 1/3] and [v3 2/3] having simple cfg80211 changes in 1/3 for easy review. Rest in 2/3 [Johannes] * used wiphy_dereference() instead of sdata_dereference() [Johannes] v2: * reabsed on ToT * removed unwanted locking sequence during cancelling CSA work handler since now locking is moved to wiphy level, that part is uncessary now. --- drivers/net/wireless/ath/ath10k/mac.c | 4 +- drivers/net/wireless/ath/ath10k/wmi.c | 2 +- drivers/net/wireless/ath/ath11k/mac.c | 2 +- drivers/net/wireless/ath/ath11k/wmi.c | 2 +- drivers/net/wireless/ath/ath12k/wmi.c | 2 +- drivers/net/wireless/ath/ath9k/beacon.c | 2 +- .../net/wireless/ath/ath9k/htc_drv_beacon.c | 2 +- .../net/wireless/intel/iwlwifi/mvm/mac-ctxt.c | 6 +- .../wireless/intel/iwlwifi/mvm/time-event.c | 2 +- drivers/net/wireless/mediatek/mt76/mac80211.c | 2 +- .../net/wireless/mediatek/mt76/mt7615/mcu.c | 2 +- .../net/wireless/mediatek/mt76/mt7915/mcu.c | 2 +- .../net/wireless/mediatek/mt76/mt7996/mcu.c | 2 +- .../wireless/realtek/rtl8xxxu/rtl8xxxu_core.c | 2 +- drivers/net/wireless/ti/wlcore/event.c | 2 +- drivers/net/wireless/virtual/mac80211_hwsim.c | 2 +- include/net/cfg80211.h | 3 + include/net/mac80211.h | 7 +- net/mac80211/cfg.c | 108 +++++++++++------- net/mac80211/link.c | 2 + net/mac80211/tx.c | 14 ++- net/wireless/nl80211.c | 1 + net/wireless/trace.h | 7 +- 23 files changed, 112 insertions(+), 68 deletions(-) base-commit: 28b3df1fe6ba2cb439ba109f095aa841fef3a54f
