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 Signed-off-by: Aditya Kumar Singh --- drivers/net/wireless/ath/ath10k/mac.c | 2 +- drivers/net/wireless/ath/ath10k/wmi.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 | 4 +- .../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/mac80211.h | 3 +- net/mac80211/cfg.c | 110 +++++++++++------- 17 files changed, 86 insertions(+), 59 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/mac.c b/drivers/net/wireless/ath/ath10k/mac.c index 090bcf148d0c..07c5c51ff7b2 100644 --- a/drivers/net/wireless/ath/ath10k/mac.c +++ b/drivers/net/wireless/ath/ath10k/mac.c @@ -2047,7 +2047,7 @@ static void ath10k_mac_vif_ap_csa_count_down(struct ath10k_vif *arvif) ath10k_warn(ar, "failed to update prb tmpl during csa: %d\n", ret);

However, with MLO, there is a need to update the counter for the beacon in a particular link. Add support to use link_id in order to fetch the beacon from a particular link data during beacon update counter.
